In some embodiments, as shown in fig. 6 to 9, the rotary connection assembly 3 includes a base 31, and a first shaft 32 and a second shaft 33 that are connected to the base 31 at intervals, wherein an axial direction of the first shaft 32 is perpendicular to the first direction, and an axial direction of the second shaft 33 is parallel to the first direction. The first rotating shaft 32 is connected to the main body 2 so that the main body 2 can be turned over relative to the bottom bracket 1, so that the main body 2 is switched between a first state (as shown in fig. 1) in which the main body 2 is stacked on the bottom bracket 1, and a second state (as shown in fig. 2) in which a third included angle is formed between the main body 2 and the bottom bracket 1; the second rotating shaft 33 includes a first end 33a and a second end 33b along the axis direction, the first end 33a is connected with the base 31, and the second end 33b is rotatably connected with the plug 41, so that the main body 2 is rotatable relative to the bottom bracket 1 when in the second state; the second end 33b is provided with a cam structure 34, and the cam structure 34 is used for driving the clamping piece 42 to move relative to the inserting piece 41 when the host body 2 rotates relative to the bottom bracket 1 to drive the second rotating shaft 33 to rotate, so as to be inserted into the clamping groove 12 or separated from the clamping groove 12, so that the inserting piece 41 is fixedly inserted into the inserting groove 11 or separated from the inserting groove 11, so that the locking structure 4 is connected with the bottom bracket 1 or separated from the bottom bracket 1, and the host body 2 is connected with the bottom bracket 1 or separated from the bottom bracket 1.

That is, the first rotation shaft 32 of the connection assembly 3 is rotated to enable the host body 2 to turn over relative to the bottom bracket 1, so that the host body 2 can switch between a first state (as shown in fig. 1) in which the host body 2 is stacked on the bottom bracket 1, and a second state (as shown in fig. 2) in which a third angle is formed between the host body 2 and the bottom bracket 1, so that the host body 2 can be stacked on the bottom bracket 1 in normal use, and the host body 2 can be made vertical relative to the bottom bracket 1 by turning over the host body 2 when a user needs to view a video, thereby facilitating the user to view the video better, and at the same time, by providing the second rotation shaft 33, when the host body 2 is turned over relative to the bottom bracket 1 to have the third angle with the bottom bracket 1, the main body 2 can be rotated to rotate the main body 2 around the second rotation axis to adjust the angle of the main body 2, so as to increase the application range of the intelligent main body, in addition, when the main body 2 rotates around the second rotation axis 33, the second rotation axis 33 rotates to rotate the cam structure 34 disposed at the second end 33b of the second rotation axis 33, and when the cam structure 34 rotates, the catch member 42 of the catch structure 4 can be driven to move relative to the plug member 41, so that the catch member 42 is inserted into the catch slot 12, so that the main body 2 is locked to the bottom bracket 1, or the catch member 42 is disengaged from the catch slot 12, so that the main body 2 is unlocked from the bottom bracket 1, so that the main body 2 can be detached from the bottom bracket 1, and the wearable main body 100 can meet various usage scenarios (for example, shooting Talk and charge the host body 2, etc.) to enhance the use experience of the wearable host 100. The cam structure 34 arranged through the second rotating shaft 33 is connected with the lock catch structure 4 in a matched manner so as to lock or unlock the lock catch structure 4 and the bottom bracket 1, so that the cam structure 34 is integrated on the second rotating shaft 33, compared with the mode of additionally arranging a pressing key to lock and unlock, the integration level of the wearable host 100 is higher, and the realization of the miniaturized design of the wearable host 100 is facilitated.

Further, because the user needs to turn the host body 2 to be in the second state and rotate by a predetermined angle relative to the bottom bracket 1 before detaching the host body 2 from the bottom bracket 1, through the design, compared with the mode of detachably connecting the host body 2 and the bottom bracket 1 by adopting the modes of magnetic attraction, fastening and the like, the possibility of separating the host body 2 from the bottom bracket 1 under the subjective intention of a non-user is lower, especially for children users and teenagers users, the situation that the host body 2 is detached from the bottom bracket 1 due to the misoperation can be avoided, and meanwhile, the situation that the host body 2 is accidentally separated from the bottom bracket 1 to fall injury can be avoided.

In some embodiments, as shown in fig. 6 to 9, the plug 41 abuts against a peripheral side of the cam structure 34, so as to move along a second direction relative to the plug 41 under the driving action of the cam structure 34, so that the fastener 42 is plugged into the slot 12 or separated from the slot 12. Through the periphery butt of fastener 42 and cam structure 34, need not to be with fastener 42 and cam structure 34 fixed connection like this, the connected mode is simpler, can realize driving fastener 42 relative plug 41 motion through setting up the shape of cam structure 34's outer peripheral face.

Illustratively, the cam structure 34 has opposite first and second abutment sides 341 and 342, and a maximum distance L1 from the first abutment side 341 to the axis O of the second rotating shaft 33 is greater than a maximum distance L2 from the second abutment side 342 to the axis O of the second rotating shaft 33; when the second rotating shaft 33 rotates to the first abutting side 341 abuts against the fastening member 42, the fastening member 42 moves along the second direction relative to the plug member 41 to be inserted into the fastening slot 12; when the second rotating shaft 33 rotates to the second abutting side 342 abuts against the fastening member 42, the fastening member 42 moves along the second direction relative to the plug member 41 until it is separated from the fastening slot 12. Thus, when the first abutment side 341 abuts against the latch member 42, the latch member 42 is further away from the axis O of the second rotating shaft 33, and at this time, the cam structure 34 drives the latch member 42 to move in a direction away from the axis O of the second rotating shaft 33, so that the latch member 42 can slide into the latch slot 12 relative to the plug member 41, so that the plug member 41 is fixed in the plug slot 11. When the second abutting side 342 abuts against the fastening member 42, the fastening member 42 is closer to the axis O of the second rotating shaft 33, and at this time, the cam structure 34 drives the fastening member 42 to move along the direction close to the axis O of the second rotating shaft 33, so that the fastening member 42 can move relative to the plug member 41 to disengage from the fastening slot 12, so that the plug member 41 can be pulled out from the plug slot 11, thereby detaching the host body 2 from the bottom bracket 1. Alternatively, the cam structure 34 may be an eccentric structure, so as to achieve that a maximum distance L1 from the first abutment side 341 to the axis O of the second rotating shaft 33 is greater than a maximum distance L2 from the second abutment side 342 to the axis O of the second rotating shaft 33.

It should be noted that, the maximum distance L1 from the first abutment side 341 to the axis O of the second rotating shaft 33 may be a distance between the edge of the first abutment side 341 and the axis O of the second rotating shaft 33, or may be a distance between an end point of the first abutment side 341 farthest from the axis O of the second rotating shaft 33 and the axis O of the second rotating shaft 33, for example, when the cam structure 34 is a square-like structure, the outer contour of the cam structure 34 is a straight line, the maximum distance L1 from the first abutment side 341 to the axis O of the second rotating shaft 33 is a distance between the edge of the first abutment side 341 and the axis O of the second rotating shaft 33, when the cam structure 34 is a cylindrical-like structure, the outer contour of the cam structure 34 is an arc, and at this time, the maximum distance L1 from the first abutment side 341 to the axis O of the second rotating shaft 33 is a distance between an end point of the first abutment side 341141 farthest from the axis O of the second rotating shaft 33 and the axis O of the second rotating shaft 33.

Similarly, the maximum distance L2 from the second abutment side 342 to the axis O of the second rotating shaft 33 may be the distance between the edge of the second abutment side 342 and the axis O of the second rotating shaft 33, or may be the distance between the end point of the second abutment side 342 farthest from the axis O and the axis O of the second rotating shaft 33, which is not illustrated herein.

In order to improve the connection stability between the locking structure 4 and the bottom bracket 1, so as to ensure that the locking structure 4 can be stably connected to the bottom bracket 1 in a locked state, in some embodiments, as shown in fig. 5 and fig. 9 to fig. 12, the locking structure 4 may include two locking pieces 42, the two locking pieces 42 are respectively located at two sides of the second rotating shaft 33, two opposite slot wall surfaces of the inserting slot 11 are respectively provided with a slot 12, the two slots 12 and the two locking pieces 42 are respectively arranged in a one-to-one correspondence, and the two slots 12 and the two locking pieces 42 are respectively inserted; the second end 33b is provided with two cam structures 34 arranged along the axial direction of the second rotating shaft 33, the two cam structures 34 are respectively abutted with the two clamping pieces 42, projections of the two cam structures 34 are at least partially staggered along the axial direction of the second rotating shaft 33, two first abutting sides 341 of the two cam structures 34 are respectively located at two opposite sides of the axial line of the second rotating shaft 33, and two second abutting sides 342 of the two cam structures 34 are respectively located at two opposite sides of the axial line of the second rotating shaft 33. That is, the two first abutment sides 341 of the two cam structures 34 are disposed opposite to each other, and the second abutment sides 342 of the two cam structures 34 are disposed opposite to each other, so that the two engaging members 42 are disposed opposite to each other, and the two cam structures 34 can simultaneously drive the two engaging members 42 to slide into the slot 12 or simultaneously disengage from the slot 12.
