[0040] The folding mechanism of the first aspect embodiment of the utility model is described below with reference to the drawings in the specification, and it should be noted that, for the convenience of understanding and description, in the embodiments of the utility model, the downward direction is indicated as the first direction, and the leftward direction is indicated as the second direction, and the first direction intersects the second direction.
[0041] The utility model embodiment provides a folding mechanism 100 convenient to fold, refer to Figures 1 to 4As shown, the folding mechanism 100 comprises a fixing member 110, a first elastic member 120, a locking member 130 and a lock body 140. The fixing member 110 has a mounting position 111, the first elastic member 120 and the locking member 130 are connected to the mounting position 111, and the first elastic member 120 is arranged between the locking member 130 and the fixing member 110 in the up-down direction. The locking member 130 has a first end 131 and a second end 132 arranged oppositely in the up-down direction, and the first end 131 and the second end 132 are end portions of the locking member 130. In addition, the locking member 130 has a first side 133 and a second side 134 arranged oppositely in the left-right direction. The first side 133 and the second side 134 have a transition surface 135 therebetween, the transition surface 135 has a first distance H1 between one end thereof facing the first side 133 and the mounting position 111, and has a second distance H2 between the other end thereof facing the second side 134 and the mounting position 111, the first distance H1 is smaller than the second distance H2, so that the transition surface 135 is an inclined surface. The locking member 130 can move in the direction from the first end 131 to the second end 132 to compress the first elastic member 120. The lock body 140 has a receiving groove 141 which is open to the outer wall of the lock body 140 in the direction from the first end 131 to the second end 132, so that the locking member 130 can enter the receiving groove 141.
[0042] For the convenience of description and understanding, the direction from the first end 131 to the second end 132 is defined as the upward direction, and the direction from the second end 132 to the first end 131 is defined as the downward direction. In this embodiment, the lock body 140 rotates relative to the fixing member 110. During the rotation, the specific position of the lock body 140 relative to the fixing member 110 changes, but the lock body 140 always first contacts the short side (i.e. the first side 133) of the transition surface 135 of the locking member 130, and then contacts the long side (i.e. the second side 134) of the transition surface 135 of the locking member 130. Therefore, the direction from the first side 133 to the second side 134 and the direction from the second side 134 to the first side 133 represent the movement direction of the lock body 140. In other embodiments, the lock body 140 can slide relative to the fixing member 110. It can be understood that, in the case of sliding, the direction from the first side 133 to the second side 134 is the rightward direction, and the direction from the second side 134 to the first side 133 is the leftward direction.
[0043] Specifically, referring to Figure 2 and Figure 3As shown, the lock body 140 can move along the first side 133 towards the second side 134, so that the end of the lock body 140 abuts against the transition surface 135. When the lock body 140 and the transition surface 135 are in contact, as the lock body 140 continuously moves, the locking piece 130 will automatically lift upwards to compress the first elastic piece 120. At this time, the first elastic piece 120, under the compression, will exert an elastic force on the locking piece 130, so that the locking piece 130 has a tendency to move downwards. Referring to Figure 4 As shown, when the lock body 140 moves along the first side 133 towards the second side 134 to the position corresponding to the locking piece 130 and the accommodating groove 141, the locking piece 130 will enter the accommodating groove 141 under the action of the first elastic piece 120. At this time, the lock body 140 is in the first state, i.e., the locked state. Due to the limitation of the locking piece 130, the lock body 140 cannot continue to move, and the locking piece 130 cannot move in the up-down direction or the left-right direction due to the limitation of the sidewall of the first elastic piece 120 and the accommodating groove 141, thereby achieving the folding locking of the folding mechanism 100. When it is necessary to unlock the folding mechanism 100, the locking piece 130 needs to be lifted upwards to compress the first elastic piece 120, so that the locking piece 130 and the accommodating groove 141 are separated. At this time, the lock body 140 is in the second state, i.e., the unlocked state. The lock body 140 can exit along the second side 134 towards the first side 133, so that the folding mechanism 100 is unlocked and unfolded.
[0044] The folding mechanism 100 of the embodiment of the utility model can set the transition surface 135 on the first end 131 of the locking piece 130, the transition surface 135 is a slope, so that when the lock body 140 abuts against the transition surface 135, the locking piece 130 will automatically move to compress the first elastic piece 120, without the need for artificially lifting the locking piece 130. Then, the first elastic piece 120 is arranged between the mounting position 111 and the locking piece 130, so that the first elastic piece 120, under the compression, has a tendency to drive the locking piece 130 to move. Thus, when the lock body 140 moves to the position corresponding to the accommodating groove 141 and the locking piece 130, the locking piece 130 will be accommodated in the accommodating groove 141 under the driving of the first elastic piece 120, thereby achieving the locking of the folding mechanism 100. Moreover, when the folding mechanism 100 is locked, the locking piece 130 is located in the accommodating groove 141, and the lock body 140 and the locking piece 130 limit each other, so that the lock body 140 and the fixing piece 110 cannot move, thereby reducing the shaking generated after folding. When the locking piece 130 is driven to move to separate from the accommodating groove 141, the lock body 140 can be unlocked.
[0045] In some embodiments, referring to Figures 1 to 4As shown, the inner part of the fixing member 110 defines a first chamber 112, the mounting position 111 and the first elastic member 120 are arranged in the first chamber 112, the first chamber 112 is communicated with the fixing member 110 in the downward direction and is formed with a first opening 1121, and the part of the locking member 130 enters and exits the first chamber 112 through the first opening 1121. Specifically, the mounting position 111 is arranged on the bottom wall of the first chamber 112 in the upward direction, and the mounting position 111 and the first opening 1121 are arranged opposite to each other in the upward and downward directions. The part of the locking member 130 is arranged outside the first chamber 112 through the first opening 1121. When the lock body 140 moves to abut against the transition surface 135, the part of the locking member 130 will retract into the first chamber 112 through the first opening 1121 under the lifting of the lock body 140 to compress the first elastic member 120. By arranging the first chamber 112, the first elastic member 120 and the part of the locking member 130 can be accommodated in the inner part of the fixing member 110, so as to reduce the overall volume of the folding mechanism 100. In addition, the first chamber 112 can provide protection for the first elastic member 120 and the locking member 130, and reduce the damage of the first elastic member 120 and the locking member 130 in the movement process. Secondly, the overall direction of the first chamber 112 is also arranged in the upward and downward directions. When the first elastic member 120 is compressed and the locking member 130 is moved, the first chamber 112 can provide a guiding effect for the first elastic member 120 and the locking member 130, so as to avoid the change of the movement direction of the first elastic member 120 and the locking member 130 in the movement process.
[0046] Further, in some embodiments, referring to Figures 1 to 4As shown, the locking member 130 further comprises a locking portion 136 and a connecting portion 137 connected with each other, and the first end 131 and the transition surface 135 are arranged on the locking portion 136. The mounting site 111 is formed with a movable hole 1122 communicating with the first chamber 112 on the outer wall of the fixing member 110, and the movable hole 1122 and the first opening 1121 are arranged opposite to each other in the up-down direction. The connecting portion 137 is arranged in the movable hole 1122. When the locking member 130 is resisted by the lock body 140 to compress the first elastic member 120, the connecting portion 137 can pass in and out of the first chamber 112 through the movable hole 1122. The position of the locking member 130 can be limited through the movable hole 1122 and the connecting portion 137, further enhancing the activity stability of the locking member 130, and reducing the situation that the locking member 130 deviates due to uneven force when the first elastic member 120 is compressed and abuts against the lock body 140. Moreover, the first elastic member 120 is arranged around the connecting portion 137, which can reduce the space volume occupied by the first elastic member 120 and the locking member 130, thereby reducing the volume of the folding mechanism 100, and at the same time, can increase the contact area of the first elastic member 120 and the locking member 130, reduce the elastic force locally received by the locking member 130, thereby enhancing the connection stability of the first elastic member 120 and the locking member 130, and improving the activity stability of the first elastic member 120.
[0047] In some embodiments, referring to Figures 1 to 4 As shown, the fixing member 110 further comprises a resisting member 150, which is arranged spaced apart from the fixing member 110 in the downward direction. The folding mechanism 100 further comprises a second elastic member 160, which is connected to the resisting member 150 in the direction from the second side 134 to the first side 133. When the lock body 140 moves in the direction from the first side 133 to the second side 134, the second elastic member 160 abuts against the lock body 140.
[0048] Specifically, when the lock body 140 moves and abuts against the transition surface 135 to lift the locking piece 130, the lock body 140 will contact the second elastic member 160, and as the lock body 140 continuously moves, the second elastic member 160 will be compressed in the direction from the first side 133 to the second side 134. When the locking piece 130 is accommodated in the accommodating groove 141 to hinder the movement of the lock body 140, the second elastic member 160 will be compressed between the abutting piece 150 and the lock body 140, at this time, the second elastic member 160 will exert a elastic force on the lock body 140, so that the lock body 140 has a tendency to move in the direction from the second side 134 to the first side 133, so that the first end 131 of the locking piece 130 abuts against the inner wall of the accommodating groove 141, improving the connection strength of the locking piece 130 and the lock body 140, and further reducing the shaking of the folding mechanism 100 after being locked. When the folding mechanism 100 needs to be unlocked, after the locking piece 130 is driven to separate from the accommodating groove 141, the lock body 140 will automatically move in the direction from the second side 134 to the first side 133 under the action of the second elastic member 160, so as to realize the automatic unlocking of the folding mechanism 100, without the need for manually moving the lock body 140 to unlock, simplifying the unlocking operation of the folding mechanism 100.
[0049] In addition, when the folding mechanism 100 is folded and locked, an external force needs to be applied to drive the lock body 140 to rotate, when the external force acting on the lock body 140 is large, causing the lock body 140 to quickly rotate, the second elastic member 160 can make the lock body 140 have a buffering force when contacting the second elastic member 160, which will inhibit the rotation of the lock body 140, so as to buffer the rapid rotation of the lock body 140, avoiding the lock body 140 directly colliding with the abutting piece 150, causing damage to the lock body 140 and the abutting piece 150, thereby improving the safety of the movement of the lock body 140.
[0050] In some embodiments, referring to Figures 1 to 4As shown, the inside of the abutting member 150 defines a second chamber 151, the second chamber 151 is formed with an opening in the abutting member 150 along the direction from the second side 134 to the first side 133, and the second elastic member 160 is arranged in the second chamber 151. Specifically, arranging the second elastic member 160 in the second chamber 151 can reduce the space occupied by the second elastic member 160, so as to reduce the overall volume of the folding mechanism 100, and the second chamber 151 can provide protection for the second elastic member 160 and reduce the damage to the second elastic member 160 during movement. Secondly, the overall direction of the second chamber 151 is also arranged along the left-right direction, and when the second elastic member 160 is compressed or rebounds to drive the lock body 140 to move, the second chamber 151 can provide a guiding effect for the second elastic member 160, so as to avoid the change of the activity direction of the second elastic member 160 during the activity. In this embodiment, when the lock body 140 moves along the direction from the first side 133 to the second side 134, the lock body 140 compresses the second elastic member 160 through the second opening 1511, that is, part of the second elastic member 160 is arranged outside the second chamber 151 through the second opening 1511, so that the lock body 140 can contact the second elastic member 160 when moving, so as to compress part of the second elastic member 160 back into the second chamber 151 through the second opening 1511.
[0051] In other embodiments, the second elastic member 160 is completely arranged in the second chamber 151, and the end of the lock body 140 is provided with a protruding portion, when the lock body 140 moves along the direction from the first side 133 to the second side 134, the protruding portion of the lock body 140 enters the second chamber 151 through the second opening 1511, so as to compress the second elastic member 160.
[0052] In some embodiments, referring to Figures 1 to 4 As shown, the folding mechanism 100 further comprises a sleeve 170, the sleeve 170 is connected to the second elastic member 160 along the direction from the second side 134 to the first side 133, and the second elastic member 160 is arranged between the sleeve 170 and the abutting member 150. When the lock body 140 moves along the direction from the first side 133 to the second side 134, the lock body 140 will abut against the sleeve 170 and compress the second elastic member 160 through the sleeve 170. By arranging the sleeve 170, the second elastic member 160 can be protected and the impact of the lock body 140 on the second elastic member 160 can be reduced, so as to prolong the service life of the second elastic member 160. And, referring to Figure 2As shown, at least a part of the sleeve 170 is accommodated in the second cavity 151, and the sleeve 170 and the abutting member 150 enclose the second elastic member 160, so that the second elastic member 160 is in an independent space. The interior of the sleeve 170 is hollow, and the independent space is formed by the interior of the sleeve 170 and the second cavity 151. Even if the connection between the second elastic member 160 and the abutting member 150 loosens during the movement, the second elastic member 160 is still in the independent space and cannot fall out or turn over relative to the abutting member 150 and the sleeve 170 to change the compression direction, so that the second elastic member 160 can still normally compress and extend to drive the lock body 140 to move away from the locking member 130 along the second side 134 toward the first side 133.
[0053] Further, in some embodiments, referring to Figures 2 to 5 As shown, the folding mechanism 100 includes two end covers 180. The two end covers 180 are connected to the second elastic member 160 and are arranged at the two ends of the second elastic member 160 along the first side 133 toward the second side 134. When the second elastic member 160 is connected to the abutting member 150 and the sleeve 170, the two end covers 180 are respectively clamped between the second elastic member 160 and the sleeve 170 and between the second elastic member 160 and the abutting member 150 to abut the inner wall of the sleeve 170 and the inner wall of the abutting member 150, respectively, thereby protecting the second elastic member 160 and reducing the friction between the second elastic member 160 and the sleeve 170 and the friction between the second elastic member 160 and the abutting member 150 during the movement, further increasing the service life of the second elastic member 160. Further, in this embodiment, referring to Figure 5 As shown, the center of the end cover 180 is provided with a through hole, and the interior of the through hole is provided with an internal thread. The two ends of the second elastic member 160 are respectively connected and fixed to the abutting member 150 and the sleeve 170 through threaded connection, thereby improving the connection strength of the second elastic member 160 and the sleeve 170 and the connection strength of the second elastic member 160 and the abutting member 150, and avoiding the loosening of the connection between the second elastic member 160 and the sleeve 170 or the abutting member 150 after being pressed multiple times.

The moving part 190 can move upward relative to the fixed part 110. When it is necessary to unlock the folding mechanism 100, the movement of the moving part 190 can drive the locking part 130 to move upward to compress the first elastic part 120, so that the locking part 130 and the accommodating groove 141 are separated, and the lock body 140 is in the second state, thereby realizing the unlocking of the folding mechanism 100. Through the moving part 190, the movement of the locking part 130 can be controlled, and the unlocking steps of the folding mechanism 100 are simplified, thereby improving the unlocking efficiency of the folding mechanism 100.

The first screen body 210 is connected to the fixed part 110 of the folding mechanism 100, and the second screen body 220 is connected to the lock body 140 of the folding mechanism 100. When it is necessary to fold the folding screen body 200, the second screen body 220 can be driven to move relative to the first screen body 210, so that the locking part 130 is accommodated in the accommodating groove 141, so that the folding mechanism 100 is in the locked state.
[0057] In the embodiment, the folding screen device 10 is folded by rotating the second screen body 220 relative to the first screen body 210, so that the locking member 130 is accommodated in the accommodating groove 141 of the locking body 140, thereby realizing the locking of the folding mechanism 100, simplifying the folding and locking operation of the folding screen device 10 by the folding mechanism 100, realizing the quick locking of the folding screen device 10, and reducing the shaking of the folding screen device 10 after folding and locking. When the folding mechanism 100 needs to be unlocked, the locking member 130 is pulled to move the locking member 130 towards the second end 132 from the first end 131 (i.e. upwards), so as to separate the locking member 130 and the accommodating groove 141. At this time, the locking body 140 can move towards the first side 133 from the second side 134, so that the second screen body 220 can rotate relative to the first screen body 210 to unfold the folding screen device 10. In other embodiments, the second screen body 220 can slide relative to the first screen body 210, so that the locking member 130 can also be accommodated in the accommodating groove 141 to realize the folding and locking of the folding screen device 10.
