In some embodiments, the second end 112 of the first body 11 is provided with the second abutted surface 14. The second abutted surface 14 can be abutted by the second fastening structure 20 to limit the rotation of the second fastening structure 20 relative to the first fastening structure 10 to a certain extent.

Referring to fig. 2 and 3, in some embodiments, the second base 20 includes a second body 21 and a plug portion 22. The second body 21 includes opposite first and second ends 211 and 212. The socket 22 is disposed at the first end 211 of the second body 21. The inserting portion 22 extends into the cavity 113 of the first housing 10, and the inserting portion 22 is provided with a first abutting surface 23 far away from the second body 21.

The first abutting surface 23 is used for abutting against the first abutted surface 13, and the process of rotating the second seat 20 around the first seat 10 is the process of rotating the first abutting surface 23 relative to the first abutted surface 13 along the first direction X or the second direction Y. When the second seat 20 rotates to the folding position along the first direction X relative to the first seat 10, the first abutting surface 23 can abut against the first abutted surface 13, so that the shake of the second seat 20 relative to the first seat 10 is reduced to a certain extent.

In some embodiments, the insertion part 22 includes two insertion walls 221 spaced apart from each other and a connecting wall 222 located between the two insertion walls 221, each insertion wall 221 is provided with a shaft hole 2211, and the shaft hole 2211 is used for cooperating with the connecting member 30 to enable the connecting member 30 to rotate relative to the second housing 20.

In certain embodiments, the second body 21 further comprises an abutment 24 extending from the second body 21. The abutting portion 24 and the inserting portion 22 are respectively located on two opposite sides of the second body 21. The abutting portion 24 includes a second abutting surface 241, and the second abutting surface 241 is configured to interfere with the second abutted surface 14, so as to limit a rotation stroke of the second seat body 20 relative to the first seat body 10 along the second direction Y.

In some embodiments, the second end 212 of the second body 21 is provided with a connecting structure 213, and the connecting structure 213 is used for connecting with the second external connection device, so that the second external connection device can rotate relative to the first housing 10.

Referring to fig. 2 and 3, in some embodiments, the connecting member 30 includes a connecting portion 33, two limiting portions 34, and two rotating shaft portions 35. The connecting portion 33 is located at the first end 31 of the connecting member 30 and is used for connecting with the first fastening structure 10. The two limiting parts 34 are respectively located at two sides of the connecting part 33, one end of each limiting part 34 is connected with the connecting part 33, and the limiting parts 34 are used for being matched with the limiting parts 40. The two rotating shaft portions 35 correspond to the two stopper portions 34, and the other end of each stopper portion 34 is connected to the corresponding rotating shaft portion 35 in a bent manner. The two rotating shaft portions 35 are located at the second end 32 of the connecting member 30 and are used for being rotatably connected with the second seat 20.

The connecting member 30 is made of an elastic material, such as metal, rubber, plastic, etc., which have certain elasticity, and is not limited herein. The elastic connection element 30 can absorb the rigid deformation caused by the force applied to the first fastening structure 10 and/or the second fastening structure 20 when the second fastening structure 20 rotates relative to the first fastening structure 10, so as to prevent the rigidity of the first fastening structure 10 and/or the second fastening structure 20 from being damaged.

In some embodiments, the two rotating shaft portions 35 of the connecting member 30 are inserted through the two shaft holes 2211 of the second seat 20 and engaged with the connecting slots 1132 on the inner sidewalls 1131 of the two opposite sides of the cavity 113 in the first seat 10, so that the connecting member 30 can connect the first seat 10 and the second seat 20 and can rotate relative to the shaft holes 2211. The connecting portion 33 is fixedly connected to the first side 121 of the combining portion 12 of the first fastening structure 10, specifically, the connecting portion 33 is disposed on the protrusion of the combining portion 12, so that the connecting portion 33 can be fixed on the first fastening structure 10.

As shown in fig. 2, in the folding mechanism 100, the first end 31 of the connecting member 30 is fixedly connected to the first seat 10, and the second end 32 of the connecting member 30 penetrates through the first seat 10 and the second seat 20 and is rotatably connected to the second seat 20, so that the first seat 10 is connected to the second seat 20, and the second seat 20 can rotate along the first direction X or the second direction Y relative to the first seat 10 and the connecting member 30. When the second seat 20 rotates relative to the first seat 10 and the connecting member 30, the limiting portion 34 has a larger rotation arm, so that the second seat 20 can rotate more easily, and the second seat 20 can be rotated to a predetermined position more easily.

Referring to fig. 5 and 6, the folding mechanism 100 shown in fig. 5 is in a locked state, and the second seat 20 rotates to a predetermined position relative to the first seat 10 and is kept at the predetermined position. The preset position illustrated in fig. 3 is the fully deployed position of the folding mechanism 100. Fig. 6 is an enlarged view of fig. 5, and as shown in fig. 6, when the second seat 20 rotates to the fully extended position relative to the first seat 10, the second abutting surface 241 cooperates with the second abutted surface 14 to prevent the second seat 20 from continuing to rotate relative to the first seat 10 along the second direction Y.

Referring to fig. 7 and 8, the folding mechanism 100 shown in fig. 7 is in an unlocked state, and the second seat 20 can freely rotate relative to the first seat 10. Fig. 8 is an enlarged view of fig. 7, and as shown in fig. 8, when the folding mechanism 100 is in the unlocked state, the second abutting face 241 is disengaged from the second abutted face 14.

When the second seat 20 rotates to a predetermined position relative to the first seat 10, the limiting member 40 cooperates with the connecting member 30 to prevent the second seat 20 from continuing to rotate relative to the first seat 10, so that the second seat 20 is kept at the predetermined position, and the folding mechanism 100 is in a locked state. When the limiting member 40 is disengaged from the connecting member 30, the second seat 20 can rotate relative to the first seat 10 to leave the predetermined position, the folding mechanism 100 is in an unlocked state, and the second seat 20 can rotate freely relative to the first seat 10.

In some embodiments, the preset position comprises a fully deployed position, a fully folded position, or a partially folded position. Wherein the partially folded position may be a position between the fully unfolded position and the fully folded position. When the second fastening structure 20 is retained at any one of the predetermined positions, the folding mechanism 100 is in the locked state, and, correspondingly, when the second fastening structure 20 is not retained at any one of the predetermined positions, the folding mechanism 100 is in the unlocked state.

For example, if the predetermined position is the fully extended position, the limiting member 40 can be correspondingly disposed on the first seat 10 or the second seat 20, and when the second seat 20 rotates to the fully extended position relative to the first seat 10, the limiting member 40 can be matched with the connecting member 30, so that the second seat 20 can be maintained at the fully extended position, that is, the folding mechanism 100 is locked at the fully extended position.

For another example, if the predetermined position is a fully folded position, the limiting member 40 can be correspondingly disposed on the first seat 10 or the second seat 20, and when the second seat 20 rotates to the fully folded position relative to the first seat 10, the limiting member 40 can cooperate with the connecting member 30, so that the second seat 20 can be kept at the fully folded position, that is, the folding mechanism 100 is locked at the fully folded position.

For another example, if the predetermined position is a partial folding position, the limiting member 40 can be correspondingly disposed on the first fastening structure 10 or the second fastening structure 20, and when the second fastening structure 20 rotates to the partial folding position relative to the first fastening structure 10, the limiting member 40 can cooperate with the connecting member 30, so that the second fastening structure 20 can be maintained at the partial folding position, that is, the folding mechanism 100 locks the partial folding position.

In some embodiments, the predetermined number of positions may be multiple, for example, the predetermined number of positions may be 1, 2, 3, 4, 5, 6, etc., which are not listed here. The number of the limiting members 40 may be plural, for example, the number of the limiting members 40 may be 1, 2, 3, 4, 5, 6, etc., which are not listed here. When the number of the limiting members 40 is multiple, the connecting member 30 can be selectively engaged with any one of the limiting members 40, so that the second seat 20 can be maintained at different preset positions.

For example, the number of the stoppers 40 is 3, and the stoppers are a first stopper 40 corresponding to a fully extended position, a second stopper 40 corresponding to a fully folded position, and a third stopper 40 corresponding to a partially folded position. When the second seat body 20 rotates to the fully extended position relative to the first seat body 10 and the first limiting member 40 is engaged with the connecting member 30, the second seat body 20 can be maintained at the fully extended position; when the second seat 20 rotates to the fully folded position relative to the first seat 10 and the second limiting member 40 is engaged with the connecting member 30, the second seat 20 can be kept at the fully unfolded position; when the second fastening structure 20 rotates to a certain partially folded position relative to the first fastening structure 10 and the third limiting element 40 is engaged with the connecting element 30, the second fastening structure 20 can be maintained at the partially folded position.

Referring to fig. 2, in some embodiments, a limiting member 40 is disposed on any one of the insertion walls 221 of the second body 21, and the limiting member 40 faces to the other insertion wall 221. Or both the insertion walls 221 of the second body 21 are provided with the limiting members 40, and the limiting members 40 face the other insertion wall 221 opposite to the other insertion wall.

The limiting member 40 may extend from the insertion wall 221, may be detachably mounted on the insertion wall 221, or may be non-detachably mounted on the insertion wall 221, which is not limited herein.

In some embodiments, the position-limiting member 40 includes a slope 41, and when the second fastening structure 20 rotates relative to the first fastening structure 10 in the folding direction, the slope 41 is used to guide the connecting member 30 to slide to release the engagement between the connecting member 30 and the position-limiting member 40.

Specifically, the position-limiting member 40 may be a positioning clip point 40, where the positioning clip point 40 includes a slope 41, a side close to the insertion wall 221 is a high point of the slope 41, and a side far from the insertion wall 221 is a low point of the slope 41. Referring to fig. 3, the cross-section 36 of the connecting member 30 is circular. When the connecting member 30 is engaged with the positioning click 40, a tangent line of the outer surface of the connecting member 30 interferes with the positioning click 40.

Referring to fig. 3, when the second seat 20 is at the predetermined position, the limiting member 40 is engaged with the connecting member 30, and one side of the positioning fastening point 40 can be abutted against a tangent line of the outer surface of the limiting portion 34, so as to prevent the second seat 20 from rotating along the first direction X relative to the first seat 10. When the cooperation between the limiting member 40 and the connecting member 30 needs to be released to allow the second seat 20 to leave the predetermined position, a certain force is continuously applied to the second seat 20 to move the second seat 20 along the high point of the slope 41 toward the low point of the slope 41 until the limiting portion 34 is released from the interference with the positioning detent 40, and then the limiting portion 34 moves to the other side of the positioning detent 40 beyond the positioning detent 40, so that the second seat 20 rotates to leave the predetermined position relative to the first seat 10.

When the predetermined position is the fully unfolded position, in one embodiment, the position-limiting portion 34 abuts against the positioning detent 40, and the second abutting surface 241 abuts against the second abutted surface 14 to jointly limit the second seat 20 to rotate along the second direction Y relative to the first seat 10, so that the second seat 20 is maintained at the fully unfolded position. In another embodiment, the position-limiting member 40 includes two positioning fastening points 40 sequentially arranged along the rotation direction, and when the connecting member 30 rotates relative to the second fastening body 20 to a position between the two positioning fastening points 40, the second fastening body 20 can be maintained at the fully extended position.

If the second seat 20 is to leave the fully extended position, the positioning and locking point 40 is rotated along the first direction X with the second seat 20 by releasing the engagement between the position-limiting portion 34 and the positioning and locking point 40, so as to move from one side of the position-limiting portion 34 to the other side of the position-limiting portion 34.

When the predetermined position is any one of the fully unfolded position, the fully folded position, or the partially folded position, in one embodiment, the position-limiting member 40 includes a plurality of positioning fastening points 40 sequentially arranged along the rotation direction, and the connecting member 30 can rotate relative to the second seat 20 to a position between any two positioning fastening points 40 to keep the second seat 20 at the predetermined position.

For example, the limiting member 40 includes a first positioning fastening point 40, a second positioning fastening point 40, a third positioning fastening point 40, and a fourth positioning fastening point 40 sequentially arranged along the first direction X, and when the limiting portion 34 is located between the first positioning fastening point 40 and the second positioning fastening point 40, the second seat 20 is in the fully folded position; when the position-limiting part 34 is between the second positioning fastening point 40 and the third positioning fastening point 40, the second seat 20 is at a certain partially folded position; when the position-limiting portion 34 is located between the third positioning-fastening point 40 and the fourth positioning-fastening point 40, the second fastening body 20 is in the fully-extended position.

Further, the location stuck point 40 may be any one of a cone, a pyramid, a combination of a cone and a cylinder, and a combination of a pyramid and a prism, which is not limited herein. Taking the example that the cooperation between the connecting member 30 and the positioning fastening point 40 and the cooperation between the second abutting surface 241 and the second abutted surface 14 limit the second seat 20 to the fully unfolded position:

in one embodiment, the positioning clip point 40 is a cone extending from the second fastening structure 20, and the cross section of the cone is gradually reduced along the direction away from the second fastening structure 20; when the connecting piece 30 is matched with the large-section end of the positioning clamping point 40, the second seat body 20 is kept at the fully unfolded position; the coupler 30 can be moved from the large section to the small section until the coupler 30 is clear of the apex of the cone to disengage the coupler 30 from the detente point 40.

In another embodiment, the positioning locking point 40 is a pyramid extending from the second seat 20, and the cross section of the pyramid gradually decreases in a direction away from the second seat 20; when the connecting piece 30 is matched with the large-section end of the positioning clamping point 40, the second seat body 20 is kept at the fully unfolded position; the connecting member 30 can be moved from the large section to the small section until the connecting member 30 is moved away from the apex of the pyramid to disengage the connecting member 30 from the locator clip 40.

In yet another embodiment, the positioning clip 40 is a combination of a cylinder and a cone extending from the second fastening structure 20, and the cylinder and the cone are sequentially arranged along a direction away from the second fastening structure 20, and the section of the cone is gradually reduced along a direction away from the second fastening structure 20; when the connecting member 30 is engaged with the cylindrical end of the positioning clip 40, the second fastening structure 20 is maintained at the fully extended position; the coupler 30 can be moved from the large section to the small section until the coupler 30 is clear of the apex of the cone to disengage the coupler 30 from the detente point 40.

In yet another embodiment, the positioning locking point 40 is a combination of a prism and a pyramid extending from the second seat 20, and the prism and the pyramid are sequentially arranged along a direction away from the second seat 20, and the cross section of the pyramid gradually decreases along the direction away from the second seat 20; when connecting member 30 is mated with the prism end of positioning click point 40, second seat 20 is maintained in the fully extended position; the connector 30 can be moved from the large section to the small section until the connector 30 is clear of the apex of the pyramid to disengage the connector 30 from the locator clip 40.

Referring to fig. 2 and 3, in some embodiments, the position limiting member 40 is a positioning slot (not shown). When the limiting portion 34 rotates relative to the second seat 20 until the limiting portion 34 partially enters the positioning slot, the second seat 20 can be kept at a position corresponding to the positioning slot.

For example, the position-limiting member 40 includes a positioning slot disposed along the rotation direction, and the positioning slot corresponds to the fully-unfolded position, and when the connecting member 30 rotates relative to the second seat 20 to the positioning slot, the second seat 20 can be maintained at the fully-unfolded position.

For another example, the limiting member 40 includes a plurality of positioning slots sequentially arranged along the rotation direction, and the positioning slots sequentially correspond to the fully folded position, a certain portion of the folded position, and the fully unfolded position along the first direction X. The connecting member 30 can rotate relative to the second fastening structure 20 to any one of the positioning slots, so that the second fastening structure 20 is kept at a predetermined position corresponding to the positioning slot.
