In the description of the present application, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0066] In the description of the present application, it is necessary to point out that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "linking" should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through intermediate medium, can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0067] The embodiment of the present application provides a plug-in pin locking mechanism, referring to Figure 1 、 Figure 10 and Figure 11 , the plug-in pin locking mechanism comprises a plug-in pin 1, a sliding block 2, a pushing assembly 3 and a reset member 4; the sliding block 2 is movably installed in the first end of the plug-in pin 1; the pushing assembly 3 is arranged in the plug-in pin 1, used for pushing the sliding block 2 to move away from the axis direction of the plug-in pin 1 and making the sliding block 2 at least partially protrude out of the plug-in pin 1; one end of the reset member 4 is arranged in the plug-in pin 1, and the other end of the reset member 4 abuts against the sliding block 2, used for driving the sliding block 2 to move close to the axis direction of the plug-in pin 1 and reset.

[0068] As an example, the plug pin locking mechanism is used to lock or unlock the first workpiece and the second workpiece, which specifically comprises a plug pin 1, a sliding block 2, a pushing assembly 3 and a reset member 4. During installation, the sliding block 2 is movably installed in the first end of the plug pin 1 along a second direction, and then the plug pin 1 is installed in the first workpiece along a first direction, and the first end of the plug pin 1 is arranged in the second workpiece, wherein the first direction and the second direction are two perpendicular or nearly perpendicular directions. For example, when the first direction is the up-down direction and the second direction is the left-right direction, the pushing assembly 3 is arranged in the plug pin 1 and is movably installed in the plug pin 1 along the first direction. Through an external force (for example, human force or a driving assembly 5), the pushing assembly 3 can be driven to move downward along the first direction, and the sliding block 2 can be pushed to move away from the axis of the plug pin 1, so that the sliding block 2 at least partially protrudes out of the plug pin 1, so that the sliding block 2 is clamped with the second workpiece, thereby locking the first workpiece and the second workpiece. One end of the reset member 4 is arranged in the plug pin 1, and the other end of the reset member 4 abuts against the sliding block 2. When the external force disappears, the pushing assembly 3 no longer pushes the sliding block 2 to move, and the reset member 4 can drive the sliding block 2 to move towards the axis of the plug pin 1, so that the sliding block 2 is reset and is not clamped with the second workpiece, thereby unlocking the first workpiece and the second workpiece. In this way, the pushing assembly 3 and the reset member 4 are arranged in cooperation. When the pushing assembly 3 is driven to move downward along the first direction by the external force, the pushing assembly 3 drives the sliding block 2 to move along the second direction to the outside of the plug pin 1 and clamp with the second workpiece, thereby locking the first workpiece and the second workpiece. When the external force disappears, the reset member 4 drives the sliding block 2 to reset along the second direction to the inside of the plug pin 1 and not to clamp with the second workpiece, thereby unlocking the first workpiece and the second workpiece, which ensures the effectiveness and safety of the locking of the plug pin locking mechanism and meets the use requirement. The reset member 4 is an elastic member, and the elasticity of the elastic member can drive the sliding block 2 to move along the second direction towards the axis of the plug pin 1, so that the sliding block 2 is reset. For example, the reset member 4 can be but is not limited to a reset spring.

[0069] In an embodiment, referring to Figure 1 , the pushing assembly 3 is connected with the plug pin 1 and is used to drive the plug pin 1 to move along the axial direction of the plug pin 1.

[0070] As an example, the plug pin locking mechanism is applied between the first workpiece and the second workpiece, controls the position of the plug pin 1, and can realize locking or unlocking of the first workpiece and the second workpiece. Specifically, an assembly hole is arranged in the first workpiece along a first direction, the pushing assembly 3 is arranged in the plug pin 1, specifically at least part of the pushing assembly 3 is movably arranged in the plug pin 1 along the first direction, and the plug pin 1 is movably arranged in the assembly hole of the first workpiece along the first direction. Through the above arrangement, the pushing assembly 3 can be driven to reciprocate along the first direction by an external force. When the pushing assembly 3 is driven to move downward along the first direction by the external force, the pushing assembly 3 first abuts against the sliding block 2 to generate a pushing force on the sliding block 2 in a direction away from the axis of the plug pin 1. The sliding block 2 is jointly constrained by the assembly hole of the first workpiece and the friction of the plug pin 1, so the sliding block 2 cannot be pushed by the pushing assembly 3. At this time, the pushing assembly 3 can drive the plug pin 1 to move along the axial direction of the plug pin 1, so that the first end of the plug pin 1 is arranged in or not arranged in the second workpiece. When the pushing assembly 3 continues to drive the plug pin 1 to move downward, the sliding block 2 as a whole protrudes out of the assembly hole of the first workpiece and is arranged in the second workpiece, so that it is not constrained by the assembly hole of the first workpiece. At this time, the pushing assembly 3 provides a pushing force on the sliding block 2 in a direction away from the axis of the plug pin 1, which is greater than the sum of the force of the return element 4 acting on the sliding block 2 and the friction between the sliding block 2 and the plug pin 1, so as to drive the sliding block 2 to move in a direction away from the axis of the plug pin 1. At least part of the sliding block 2 protrudes out of the plug pin 1 and is clamped with the second workpiece, so that the first workpiece and the second workpiece are locked. When the external force disappears, the return element 4 provides a pushing force on the sliding block 2 in a direction close to the axis of the plug pin 1, which is greater than the friction between the sliding block 2 and the plug pin 1, so as to drive the sliding block 2 to move in a direction close to the axis of the plug pin 1 and reset. At this time, the pushing assembly 3 can drive the plug pin 1 and the sliding block 2 as a whole to move along the axial direction of the plug pin 1 under the action of the external force, so as to unlock the first workpiece and the second workpiece.

[0071] In the plug pin locking mechanism in the example, the plug pin 1 arranged in the first workpiece is controlled to move along the first direction by the pushing assembly 3, so that the plug pin 1 is arranged in or not arranged in the second workpiece, and locking or unlocking of the first workpiece and the second workpiece in the second direction is realized. Then, the sliding block 2 is controlled to move along the second direction by the pushing assembly 3 cooperating with the return element 4, so that the sliding block 2 is clamped with or not clamped with the second workpiece, and locking or unlocking of the first workpiece and the second workpiece in the first direction is realized. In this way, locking or unlocking of the first workpiece and the second workpiece in two directions can be quickly realized, and the safety of the equipment is improved.

[0072] In an embodiment, referring to Figure 1 , the pushing assembly 3 includes a pushing block 31 and a pushing rod 32. The pushing block 31 is movably arranged in the plug pin 1. The first end of the pushing rod 32 is arranged in the plug pin 1 and connected with the pushing block 31.

[0073] As an example, the pushing assembly 3 comprises a pushing block 31 and a pushing rod 32; the pushing block 31 is movably installed in the plug-in pin 1 along the first direction; the first end of the pushing rod 32 is arranged in the plug-in pin 1 and connected with the pushing block 31; in this way, the pushing rod 32 is driven to reciprocate along the first direction by external force, so as to drive the pushing block 31 to reciprocate along the first direction in the plug-in pin 1, so as to realize the extrusion or non-extrusion of the sliding block 2.

[0074] In an embodiment, referring to Figure 1 and Figure 4 , the pushing block 31 comprises a pushing block body 311, a tapered portion 312 extending from the first end of the pushing block body 311, and a connecting portion 313 extending from the second end of the pushing block body 311; the pushing block body 311 is movably installed in the plug-in pin 1, the connecting portion 313 is used for being connected with the first end of the pushing rod 32, and the tapered portion 312 is matched with the sliding block 2.

[0075] As an example, the pushing block 31 comprises a pushing block body 311, a tapered portion 312 and a connecting portion 313; the tapered portion 312 extends from the first end of the pushing block body 311, and the connecting portion 313 extends from the second end of the pushing block body 311; in installation, the pushing block body 311 is movably installed in the plug-in pin 1 along the first direction, the connecting portion 313 is used for being connected with the first end of the pushing rod 32, and the tapered portion 312 is matched with the sliding block 2; in this way, the pushing block 31 is driven to move along the first direction by the pushing rod 32, so as to facilitate the pushing of the sliding block 2 along the second direction, and realize the clamping with the second workpiece.

[0076] In an embodiment, referring to Figure 1 , the pushing assembly 3 further comprises a first spring 33 and a second spring 34; the first spring 33 and the second spring 34 are sleeved on the pushing rod 32; the first end of the first spring 33 is connected with the second end of the plug-in pin 1; the first end of the second spring 34 is connected with the pushing block 31, and the second end of the second spring 34 is connected with the plug-in pin 1.

[0077] As an example, the pushing assembly 3 further comprises a first spring 33 and a second spring 34; in installation, the first spring 33 is sleeved on the pushing rod 32 along the first direction, the first end of the first spring 33 is connected with the second end of the plug-in pin 1, and the second end of the first spring 33 is connected with the first workpiece, so as to tighten the plug-in pin 1 by the first spring 33; the second spring 34 is arranged to be sleeved on the pushing rod 32 along the first direction, the first end of the second spring 34 is connected with the pushing block 31, and the second end of the second spring 34 is connected with the plug-in pin 1, so as to tighten the pushing block 31 by the second spring 34.

[0078] For example, when the first direction is the vertical direction and the second direction is the horizontal direction, the plug-in pin locking mechanism is used to realize the locking or unlocking operation of the first workpiece and the second workpiece as follows:

[0079] (1) When the operator manually or by driving assembly 5 provides power to drive the push rod 32 to move downward in the first direction, because the elastic force of the second spring 34 is smaller than the elastic force of the first spring 33, in this state, when the push assembly 3 is driven to move downward in the first direction by external force, the push rod 32 drives the push block 31 to first abut against the sliding block 2, generating a pushing force to the sliding block 2 to move away from the axis of the latch 1, the sliding block 2 is jointly constrained by the assembly hole of the first workpiece and the friction force of the latch 1, so the sliding block 2 will not be pushed by the push block 31; at this time, the first spring 33 is released first and then drives the latch 1 to move downward in the first direction, in the process of moving downward, when the first end of the latch 1 protrudes from the assembly hole of the first workpiece to a preset operating position, it stops, the preset operating position is the position where the sliding block 2 in the latch 1 protrudes from the assembly hole of the first workpiece and penetrates into the second workpiece.

[0080] (2) When the operator manually or by driving assembly 5 provides power to continue to drive the push rod 32 to move downward in the first direction, the second spring 34 begins to release and then drives the push block 31 to move downward in the first direction, the push block 31 provides a pushing force to the sliding block 2 to move away from the axis of the latch 1, which is greater than the sum of the force of the reset member 4 to the sliding block 2 and the friction force between the sliding block 2 and the latch 1, thereby driving the sliding block 2 to move away from the axis of the latch 1, so that the sliding block 2 at least partially protrudes out of the latch 1, at this time, the reset member 4 is in a compressed state, and the first workpiece and the second workpiece are in a locked state. That is, the latch 1 will form a self-locking under the pulling force in the first direction, specifically, the downward pushing force of the push rod 32 keeps the first spring 33 and the second spring 34 in a reset state, and at the same time, the push block 31 keeps a lateral pushing force to the sliding block 2, so that the sliding block 2 keeps protruding from the assembly hole of the first workpiece and forms a clamping state with the first workpiece to lock the second workpiece.

[0081] (3) When the external force disappears, the reset member 4 is in a released state, the reset member 4 provides a pushing force to the sliding block 2 to move close to the axis of the latch 1, which is greater than the sum of the force of the push block 31 to the sliding block 2 and the friction force between the sliding block 2 and the latch 1, to drive the sliding block 2 to move close to the axis of the latch 1 and reset, thereby driving the push block 31 and the push rod 32 to move upward in the first direction. In this process, because the elastic force of the second spring 34 is smaller than the elastic force of the first spring 33, the sliding block 2 is retracted into the inside of the latch 1 under the elastic force of the reset member 4, the sliding block 2 provides a force to the push block 31, so that the push block 31 and the push rod 32 move upward in the first direction, so that the second spring 34 is completely compressed, and the push block 31 does not contact the sliding block 2, the sliding block 2 is completely retracted into the inside of the latch 1, so that the sliding block 2 can move in the first direction, but cannot move in the second direction.

[0082] (4) When the operator manually or by driving assembly 5 provides power, push rod 32 moves upward in the first direction, driving pin 1 to move upward, so that first spring 33 is fully compressed, and pin 1 is fully withdrawn into the assembly hole of the first workpiece, so that the first workpiece and the second workpiece are in the unlocked state.

[0083] In an embodiment, referring to Figure 1 and Figure 4 , the sliding block 2 is a magnetic attraction piece; the outer side of the push block 31 is provided with a groove; the push assembly 3 further comprises a permanent magnet 35 matched with the magnetic attraction piece, and the permanent magnet 35 is arranged in the groove.

[0084] As an example, the push assembly 3 further comprises a permanent magnet 35, which is installed on the outer side of the tapered portion 312 of the push block 31, and the sliding block 2 is a magnetic attraction piece, and the permanent magnet 35 is matched with the sliding block 2 to assist the sliding block 2 to move to the inside of the pin 1.

[0085] In an embodiment, referring to Figure 1 and Figure 2 , the pin 1 comprises a pin body 11, a first movable channel 12 arranged on the pin body 11 in the axial direction of the pin body 11, and a second movable channel 13 arranged on the pin body 11 in the radial direction of the pin body 11; the push assembly 3 is movably installed in the first movable channel 12; the sliding block 2 is movably installed in the second movable channel 13; one end of the reset member 4 is installed in the pin body 11, and the other end of the reset member 4 abuts against the sliding block 2.

[0086] As an example, the latch 1 comprises a latch body 11, a first movable channel 12 and a second movable channel 13, the first movable channel 12 is arranged on the latch body 11 along the axial direction of the latch body 11, and the second movable channel 13 is arranged on the latch body 11 along the radial direction of the latch body 11. The push assembly 3 is movably arranged in the first movable channel 12, so that the push assembly 3 moves in the first movable channel 12 along the axial direction of the latch body 11, i.e. the first direction. The slider 2 is movably arranged in the second movable channel 13, so that the slider 2 moves in the second movable channel 13 along the radial direction of the latch body 11, i.e. the second direction. One end of the reset member 4 is arranged on the latch body 11, specifically, can be arranged on the inner wall of the first movable channel 12, or can be arranged on the inner wall of the second movable channel 13, and the other end of the reset member 4 abuts against the slider 2. In the example, a first mounting groove is arranged on the inner wall of the second movable channel 13, one end of the reset member 4 is arranged in the mounting groove, and the other end of the reset member 4 abuts against the slider 2. With the above design, the push assembly 3 reciprocates in the first movable channel 12, which can press or not press the slider 2, and when the slider 2 is pressed, the slider 2 moves outward in the second movable channel 13; the reset member 4 can make the slider 2 move inward in the second movable channel 13, so as to reset.

[0097] In an embodiment, referring to Figure 1 , the plug-in and plug-out lock mechanism further comprises a driving assembly 5; the driving assembly 5 is connected with the pushing assembly 3, and is used to drive the pushing assembly 3 to move.

[0098] As an example, the plug pin locking mechanism further comprises a driving assembly 5; when installed, the driving assembly 5 can be arranged on the first workpiece or other workpieces, and is connected with the pushing assembly 3 for driving the pushing assembly 3 to move. The specific operation process is as follows:

[0099] (1) When the driving assembly 5 provides downward power to drive the push rod 32 to move downward in the first direction, the push rod 32 drives the push block 31 to first abut against the sliding block 2, and generates a pushing force on the sliding block 2 to move away from the axis of the plug pin 1; the sliding block 2 is jointly constrained by the assembly hole of the first workpiece and the friction force of the plug pin 1 (i.e. the friction force of the inner wall of the second movable channel 13), so the sliding block 2 cannot be pushed by the push block 31; at this time, the first spring 33 is first released to drive the plug pin 1 to move downward in the first direction, and the plug pin 1 stops moving downward when the first end of the plug pin 1 extends out of the assembly hole of the first workpiece to a preset operating position.

[0100] (2) When the driving assembly 5 continues to provide downward power to make the push rod 32 continue to move downward in the first direction, the second spring 34 begins to release to drive the push block 31 to move downward in the first direction, and the push block 31 provides a pushing force on the sliding block 2 to move away from the axis of the plug pin 1, which is greater than the sum of the force of the reset member 4 on the sliding block 2 and the friction force between the plug pin 1 and the sliding block 2, so as to drive the sliding block 2 to move away from the axis of the plug pin 1 and at least partially protrude out of the plug pin 1; at this time, the reset member 4 is in a compressed state, and the first workpiece and the second workpiece are in a locked state.

[0101] (3) When the driving assembly 5 does not provide power, i.e. the external force disappears, the reset member 4 is in a released state, and the reset member 4 provides a pushing force on the sliding block 2 to move close to the axis of the plug pin 1, which is greater than the sum of the force of the push block 31 on the sliding block 2 and the friction force between the sliding block 2 and the plug pin 1, so as to drive the sliding block 2 to move close to the axis of the plug pin 1 and reset to the inside of the plug pin 1, drive the push block 31 and the push rod 32 to move upward in the first direction, so that the second spring 34 is completely compressed, the push block 31 does not contact the sliding block 2, so that the sliding block 2 can move in the first direction, but cannot move in the second direction.

[0102] (4) When the driving assembly 5 continues to provide upward power to make the push rod 32 continue to move upward in the first direction, drive the plug pin 1 to move upward, the first spring 33 is completely compressed and the plug pin 1 is completely withdrawn into the assembly hole of the first workpiece, so that the first workpiece and the second workpiece are in an unlocked state.

[0103] In an embodiment, referring to Figure 1 and Figure 5 , the driving assembly 5 comprises a motor 51 and a driving member 52; the first end of the driving member 52 is connected with the motor 51, and the second end of the driving member 52 is connected with the pushing assembly 3.

[0104] As an example, the driving assembly 5 comprises a motor 51 and a driving member 52; when installed, the motor 51 is arranged on the first workpiece, the first end of the driving member 52 is connected with the motor 51, and the second end of the driving member 52 is connected with the pushing assembly 3, specifically connected with the second end of the push rod 32 of the pushing assembly 3; in this way, by controlling the motor 51 to rotate forward or reversely, the pushing assembly 3 can be driven to move reciprocatingly along the first direction by the driving member 52, so as to drive the latch 1 to move reciprocatingly along the first direction, so that the first end of the latch 1 is arranged in or not arranged in the second workpiece; at the same time, the pushing assembly 3 is movably arranged in the latch 1 along the first direction, the sliding block 2 moves outwardly along the second direction, and the sliding block 2 is clamped with the second workpiece, so as to lock the first workpiece and the second workpiece; the reset member 4 is arranged between the latch 1 and the sliding block 2, and the sliding block 2 can be driven to move inwardly along the second direction by the reset member 4, so that the sliding block 2 is not clamped with the second workpiece, so as to unlock the first workpiece and the second workpiece.

[0105] In this example, the motor 51 is preferably a direct current brushless motor, and the driving member 52 can be a synchronous belt assembly, comprising a synchronous belt and two synchronous wheels, the inner wall of the synchronous wheel is provided with an internal thread, and the outer side is provided with a synchronous belt tooth, one synchronous wheel is installed on the output shaft of the motor 51, and the other synchronous wheel is installed on the first end of the push rod 32, and the synchronous belt is sleeved on the two synchronous wheels; the push rod 32 comprises a first connecting section, a second connecting section and a third connecting section arranged in sequence along the first direction, the diameter of the first connecting section is greater than the diameter of the second connecting section, and the diameter of the second connecting section is greater than the diameter of the third connecting section; the first connecting section is arranged in the assembly hole of the first workpiece and the first mounting hole 121 of the first movable channel 12 of the latch 1, and the first connecting section is provided with external threads arranged along the first direction, which is matched with the driving member 52; the second connecting section is arranged in the first movable channel 12 of the latch 1, and the third connecting section is installed on the push block 31, the first spring 33 is sleeved on the first connecting section, and the second spring 34 is sleeved on the second connecting section.

[0106] In an embodiment, the plug-in and pull-out latch locking mechanism further comprises a housing 9, and the housing 9 is provided with an assembly space; the latch 1 is installed in the assembly space; at least part of the pushing assembly 3 is installed in the assembly space.

[0107] As an example, the plug pin locking mechanism further comprises a housing 9, which serves as a reference and supports installation. The housing 9 can be installed in the first workpiece and provided with an assembly hole in the first direction. In this example, the housing 9 is provided with an assembly space, the plug pin 1 is installed in the assembly space, the sliding block 2 is movably installed in the first end of the plug pin 1, and one end of the reset member 4 is arranged in the plug pin 1. The other end of the reset member 4 abuts against the sliding block 2, so that the sliding block 2 and the reset member 4 are also installed in the assembly space. At least part of the pushing assembly 3 is installed in the assembly space. Specifically, part of the pushing assembly 3 is assembled in the assembly space and arranged in the plug pin 1, and the other part of the pushing assembly 3 is assembled outside the assembly space, so that the user can directly operate and provide an external force. Alternatively, the other part of the pushing assembly 3 is connected with the driving assembly 5 to provide an external force through the driving assembly 5.

[0108] In this example, the pushing assembly 3 is arranged in the plug pin 1, the sliding block 2 and the reset member 4 are assembled in the plug pin 1, the plug pin 1 is movably installed in the housing 9 in the first direction, and finally the housing 9 is assembled in the assembly hole of the first workpiece. When the pushing assembly 3 is driven by the external force to move downward in the first direction, the pushing assembly 3 first abuts against the sliding block 2 to generate a pushing force on the sliding block 2 to move away from the axis of the plug pin 1. The sliding block 2 is jointly constrained by the housing 9 and the friction between the sliding block 2 and the plug pin 1, so it cannot move in the radial direction of the plug pin 1, but can drive the plug pin 1 to move in the axial direction of the plug pin 1, so that the first end of the plug pin 1 is arranged in or not arranged in the second workpiece. When the pushing assembly 3 continues to move downward to push the plug pin 1, the sliding block 2 protrudes from the assembly hole of the housing 9 and the first workpiece to be arranged in the second workpiece, so it is not constrained by the assembly hole of the first workpiece. At this time, the pushing assembly 3 provides a pushing force on the sliding block 2 to move away from the axis of the plug pin 1, which is greater than the sum of the force of the reset member 4 on the sliding block 2 and the friction between the sliding block 2 and the plug pin 1, so as to drive the sliding block 2 to move away from the axis of the plug pin 1 and at least partially protrude from the plug pin 1 to be clamped with the second workpiece, thereby locking the first workpiece and the second workpiece. When the external force disappears, the reset member 4 provides a pushing force on the sliding block 2 to move close to the axis of the plug pin 1, which is greater than the friction between the sliding block 2 and the plug pin 1, so as to drive the sliding block 2 to move close to the axis of the plug pin 1 and reset, so that the sliding block 2 is located in the plug pin 1 and is not clamped with the second workpiece. At this time, the pushing assembly 3 can drive the plug pin 1 and the sliding block 2 to move in the axial direction of the plug pin 1 under the action of the external force, so as to unlock the first workpiece and the second workpiece.

[0109] The embodiment of the present application provides a seat assembly, referring to Figure 8 and Figure 9 , comprising a seat frame 6 and a plug pin locking mechanism. The plug pin locking mechanism is arranged in the seat frame 6 and used for locking or unlocking the seat frame 6.

[0110] As an example, the seat assembly comprises a seat frame 6 and a latch mechanism; the seat frame 6 is a first workpiece; a second workpiece is a structural member for mounting the seat assembly, the seat frame 6 is mounted on the second workpiece through a moving wheel; the latch mechanism is applied between the seat frame 6 and the second workpiece, and by controlling the position of the latch mechanism, the seat frame 6 can be locked or unlocked with the second workpiece. The latch mechanism comprises a latch 1, a slider 2, a pushing assembly 3 and a reset member 4. When installing, the slider 2 is movably installed in the first end of the latch 1 along the second direction, and then the latch 1 is installed in the seat frame 6 along the first direction, and the first end of the latch 1 is arranged in the second workpiece; or, the latch 1, the slider 2, the pushing assembly 3 and the reset member 4 are integrally assembled in the assembly space of the housing 9, and then the housing 9 is integrally assembled in the assembly hole of the first workpiece.

[0111] For example, when the first direction is the up-down direction and the second direction is the left-right direction, the pushing assembly 3 is arranged in the latch 1, specifically movably installed in the latch 1 along the first direction, and by external force, the pushing assembly 3 can be moved downward along the first direction, and the slider 2 can be pushed to move away from the axis of the latch 1, so that the slider 2 at least partially protrudes out of the latch 1, so that the slider 2 is clamped with the second workpiece (here, the second workpiece can be the floor 8 on which the seat frame 6 is mounted), thereby locking the seat frame 6 with the second workpiece; one end of the reset member 4 is arranged in the latch 1, and the other end of the reset member 4 abuts against the slider 2, and when the external force disappears, the pushing assembly 3 no longer pushes the slider 2 to move, and the reset member 4 can drive the slider 2 to move towards the axis of the latch 1, so that the slider 2 is reset and does not clamp with the second workpiece, thereby unlocking the seat frame 6 with the second workpiece. In this way, the pushing assembly 3 and the reset member 4 are arranged in cooperation, when the pushing assembly 3 is driven to move downward along the first direction by external force, the pushing assembly 3 drives the slider 2 to move along the second direction to the outside of the latch 1 and clamp with the second workpiece, thereby locking the seat frame 6 with the second workpiece; when the external force disappears, the reset member 4 resets the slider 2 along the second direction to the inside of the latch 1 and does not clamp with the second workpiece, thereby unlocking the seat frame 6 with the second workpiece; the effectiveness and safety of the latch mechanism are ensured, and the use requirements are met.

[0112] The plug-in pin locking mechanism is applied between the seat frame 6 and the second workpiece, controls the position of the plug-in pin 1, and can realize locking or unlocking of the seat frame 6 and the second workpiece. Specifically, an assembly hole is arranged in the seat frame 6 along a first direction, the push assembly 3 is arranged in the plug-in pin 1, specifically at least part of the push assembly 3 is movably arranged in the plug-in pin 1 along the first direction, and then the plug-in pin 1 is movably arranged in the assembly hole of the seat frame 6 along the first direction. In this way, the push assembly 3 can be driven to reciprocate along the first direction by an external force. When the push assembly 3 is driven to move downward along the first direction by the external force, the push assembly 3 first abuts against the sliding block 2, and a pushing force of the sliding block 2 moving away from the axis of the plug-in pin 1 is generated. The sliding block 2 is jointly constrained by the assembly hole of the seat frame 6 and the friction of the plug-in pin 1, so the sliding block 2 cannot be pushed by the push assembly 3. At this time, the push assembly 3 can drive the plug-in pin 1 to move along the axial direction of the plug-in pin 1, so that the first end of the plug-in pin 1 is arranged in or not arranged in the second workpiece. When the push assembly 3 continues to drive the plug-in pin 1 to move downward, the sliding block 2 protrudes out of the assembly hole of the seat frame 6 and is arranged in the second workpiece, so that the sliding block 2 is not constrained by the assembly hole of the seat frame 6. At this time, the push assembly 3 provides the sliding block 2 with a pushing force of moving away from the axis of the plug-in pin 1, which is greater than the sum of the force of the return element 4 acting on the sliding block 2 and the friction between the sliding block 2 and the plug-in pin 1, so as to drive the sliding block 2 to move away from the axis of the plug-in pin 1, and at least part of the sliding block 2 protrudes out of the plug-in pin 1 and is clamped with the second workpiece, so that the seat frame 6 and the second workpiece are locked. When the external force disappears, the return element 4 provides the sliding block 2 with a pushing force of moving close to the axis of the plug-in pin 1, which is greater than the friction between the sliding block 2 and the plug-in pin 1, so as to drive the sliding block 2 to move close to the axis of the plug-in pin 1 and reset, so that the sliding block 2 is located in the plug-in pin 1 and is not clamped with the second workpiece. At this time, the push assembly 3 can drive the plug-in pin 1 and the sliding block 2 to move along the axial direction of the plug-in pin 1 as a whole under the action of the external force, so as to unlock the seat frame 6 and the second workpiece.

[0113] In the plug-in pin locking mechanism in the example, the plug-in pin 1 arranged in the seat frame 6 is controlled to move along the first direction by the push assembly 3, so that the plug-in pin 1 is arranged in or not arranged in the second workpiece, and locking or unlocking of the seat frame 6 and the second workpiece in the second direction is realized. Then the sliding block 2 is controlled to move along the second direction by the push assembly 3 cooperating with the return element 4, so that the sliding block 2 is clamped or not clamped with the second workpiece, and locking or unlocking of the seat frame 6 and the second workpiece in the first direction is realized. In this way, the seat frame 6 and the second workpiece can be quickly locked or unlocked in two directions, and the safety of the equipment is improved.

When the coil 73 is reversely energized, the reversible magnet 72 is reversely magnetized, and the N level and S level of the magnetic field are reversed, at this time the magnetic induction lines of the electric permanent magnetic locking mechanism 7 are inside and the outside has no magnetic induction lines, so that the electric permanent magnetic locking mechanism 7 has no external attractive force, the electric permanent magnetic locking mechanism 7 and the second workpiece are separated, and are unlocked.
