Description

Technical Field

[0001] The present application relates to the technical field of damping devices, and in particular to a damping buffer mechanism and a push-pull device. Background Art

[0002] In production or life, a buffer structure with a spring is usually added to at least one of the two objects sliding relative to each other to reduce the relative collision between the two objects. However, the current buffer structure does not have a self-locking limit function. Therefore, when the two objects are buffered and enter the reset process, the two objects may collide or separate due to the excessive rebound force of the spring. Summary of the invention

[0003] In view of the above, it is necessary to propose a damping buffer mechanism to solve the problem that the current buffer mechanism does not have the self-locking limit function, which is helpful to avoid collision or separation between two objects during the resetting process.

[0004] The embodiment of the present application provides a damping and buffering mechanism, which comprises a fixed component and a sliding component; the fixed component comprises a fixed member, a pushing member and a resisting member; the pushing member is connected to the fixed member; the resisting member is connected to the fixed member and is arranged on the same side of the fixed member with a spacing as the pushing member; the sliding component comprises a base, an elastic member, a limiting member and a torsion spring; the base is arranged opposite to the fixed member; the elastic member is arranged on the side of the base facing the fixed member; the limiting member comprises a main body and a stopper, the main body is rotatably connected to the base and abuts against the resisting member, the stopper is connected to one end of the main body for stopping the pushing member, and the distance between the stopper and the rotation center of the main body is smaller than the distance between the pushing member and the resisting member; The torsion spring is arranged on the base, and the two ends of the torsion spring respectively abut the base and the main body, and under the action of the torsion spring, the stop body abuts against the base; wherein, when the base moves relative to the fixing member along a first direction under the action of an external force, the pushing member can abut and compress the elastic member, and the abutting member pushes the main body to rotate relative to the base, so that the stop body rotates to the side of the pushing member away from the abutting member, and when the external force applied to the base is withdrawn, the elastic force released by the elastic member pushes the base to move in the opposite direction of the first direction so that the stop body abuts against the pushing member to achieve self-locking, and when the base moves relative to the fixing member in the opposite direction of the first direction under the action of an external force, the stop body is deformed and disengaged from the pushing member to achieve unlocking.

[0005] When the damping and buffering mechanism is used to fix two objects, the fixing member and the base can be fixedly connected to the two objects respectively, and the base can be pulled to make the base slide relative to the fixing member. In this process, the pushing member compresses the elastic member. When the elastic member is compressed, the elastic member plays a buffering role. In addition, when the elastic member is compressed, the abutting member pushes the main body of the limit member, so that the limit member rotates relative to the base until the stopper of the limit member moves to the side of the pushing member away from the abutting member. Then, the force applied to the base is canceled, and the elastic force of the compressed elastic member is released to push the pushing member to move until the pushing member contacts the limit member. At this time, the pushing member, the abutting member, the limit member, the elastic member and the torsion spring are in a force balance state, so that the base and the fixing member form a self-locking state. When force is applied to the base again to break the balance state, the base returns to its initial position. Therefore, the above-mentioned damping and buffering mechanism realizes buffering during the relative movement of the fixed component and the sliding component through the elastic part. When the sliding component is reset, it needs to be unlocked before it can return to the initial position. During this process, the elastic force of the elastic part is gradually released. Therefore, the two objects using the damping and buffering mechanism avoid the phenomenon of misalignment, separation or collision of the two objects due to excessive elastic force of the elastic part.

[0062] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0063] In the description of the present application, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, in the description of the present application, it should be noted that the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0064] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication, it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0065] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0066] See also Figure 1 The present application also discloses a push-pull device 1000, which includes a damping and buffering mechanism 100, a positioning member 200 and a movable member 300. The damping and buffering mechanism 100 provided in the embodiment of the present application includes a fixed component 10 and a sliding component 20. A movable groove 201 is provided on the positioning member 200, and the movable member 300 is accommodated in the movable groove 201. A connecting portion 301 is convexly provided on the movable member 300, and the connecting portion 301 is slidably connected to the top wall 202 of the movable groove 201. The fixed component 10 is installed on the top wall 202 of the movable groove 201, and the sliding component 20 is installed on the side of the movable member 300 facing the top wall 202 and is located on one side of the connecting portion 301.

[0067] During the use of the damping and buffering mechanism 100, the damping and buffering mechanism 100 exists in two states, namely, a buffering state and a self-locking state. When the fixed component 10 and the sliding component 20 are in the buffering state, the fixed component 10 and the sliding component 20 are used to buffer the movable part 300, thereby preventing the positioning component 200 and the movable part 300 from colliding with each other. When the movable part 300 is reset, the fixed component 10 and the sliding component 20 will enter the self-locking state, and the fixed component 10 and the sliding component 20 will limit the movable part 300. At this time, the movable part 300 has not yet returned to the initial position. When it is necessary to restore the movable part 300 to the initial position, it is only necessary to apply an external force to the sliding component 20 to release the self-locking state of the damping and buffering mechanism 100.

[0068] For ease of understanding, Figure 1 The positive direction indicated by the arrow of the X-axis shown in is the first direction.

[0069] For example, the push-pull device 1000 can be a sliding door, that is, the positioning member 200 is a door frame, the movable member 300 is a door body, and the movable member 300 can slide relative to the positioning member 200 along the X-axis direction. When the movable member 300 slides to the right, it represents opening the sliding door, and when the movable member 300 slides to the left, it represents closing the sliding door. When the movable member 300 is pulled to the left, the damping buffer mechanism 100 enters a buffering state to buffer the movable member 300 to prevent the movable member 300 from colliding with the positioning member 200; when the damping buffer mechanism 100 enters a self-locking state, at this time, the movable member 300 stops moving and keeps the sliding door closed. When the sliding door needs to be opened, an external force is applied to the movable member 300 to unlock the damping buffer mechanism 100, and the movable member 300 moves to the right under the action of the damping buffer mechanism 100 to automatically open the sliding door. In other embodiments, the push-pull device 1000 can also be a push-pull drawer or a housing of an equipment. See also Figure 2 The fixing assembly 10 includes a fixing member 11, a pushing member 12 and a resisting member 13. The fixing member 11 is a plate-like structure, and the fixing member 11 may be rectangular. The pushing member 12 is connected to the fixing member 11. In the present embodiment, the pushing member 12 and the fixing member 11 are an integral structure, and the pushing member 12 and the fixing member 11 are made of a metal plate by a stamping process. For example, the pushing member 12 and the fixing member 11 are stamped on a metal plate, and at this time, one end of the pushing member 12 is integrally connected to the fixing member 11, and the other end of the pushing member 12 is used to resist the sliding assembly 20.

[0070] Since the pusher 12 and the fixing member 11 are made in one piece, the processing of the pusher 12 and the fixing member 11 is convenient, and the operator can process the pusher 12 while processing the fixing member 11, thereby saving the processing and manufacturing time. In addition, the fixing member 11 and the pusher 12 are simple to stamp and easy to operate. In other embodiments, the pusher 12 can be fixed to the fixing member 11 by welding.

[0071] See also Figure 2 The push member 12 includes a connecting body 121 and a pushing portion 122. The connecting body 121 is a plate-like structure, and the connecting body 121 may be rectangular. One end of the connecting body 121 is integrally connected to the fixing member 11. The pushing portion 122 is also a plate-like structure. One end of the pushing portion 122 is integrally connected to the other end of the connecting body 121. The width of the pushing portion 122 is smaller than the width of the connecting body 121. The pushing portion 122 is used to push the sliding assembly 20. In this embodiment, since the width of the connecting body 121 is greater than the width of the pushing portion 122, the connecting body 121 can enhance the strength of the push member 12, and prevent the push member 12 from being deformed or broken during the process of pushing the sliding assembly 20.

[0072] See also Figure 2The resisting member 13 is disposed on the fixing member 11 and is disposed on the same side as the pushing member 12 . The resisting member 13 and the pushing member 12 are disposed at two ends of the fixing member 11 with a spacing therebetween. The resisting member 13 is used to resist and push the sliding assembly 20 .

[0073] See also Figure 2 The sliding assembly 20 includes a base 21, an elastic member 22, a stopper 23 and a torsion spring 24. The base 21 is arranged opposite to the fixing member 11, and the base 21 can slide relative to the fixing member 11. The elastic member 22 is connected to the base 21, for example, the elastic member 22 can be a spring, one end of the elastic member 22 is connected to the base 21, and the other end of the elastic member 22 is used to abut against the pusher 12.

[0074] See also Figure 2 and Figure 3 The base 21 includes a mounting member 211 and a receiving member 212. The mounting member 211 is arranged opposite to the fixing member 11 and can slide relative to the fixing member 11, and the limiting member 23 is rotatably connected to the mounting member 211. In this embodiment, the mounting member 211 includes a mounting body 2111, two supporting bodies 2112 and a rotating pin 2113. The mounting body 2111 is a long plate-like structure and extends along the X-axis direction. Each supporting body 2112 is a triangular structure. The two supporting bodies 2112 are arranged on the mounting body 2111 at intervals and are perpendicular to the mounting body 2111. For example, the supporting body 2112 can be integrally formed with the mounting body 2111. The supporting body 2112 and the mounting body 2111 are processed by a stamping process, and the supporting body 2112 is used to support the limiting member 23. Since the supporting body 2112 and the mounting body 2111 are made by a stamping process, the supporting body 2112 and the mounting body 2111 are quickly processed. The two ends of the rotating pin 2113 are respectively rotatably connected to the two supporting bodies 2112, and the extending direction of the rotating pin 2113 is perpendicular to the extending direction of the mounting body 2111. The rotating torsion spring 24 is sleeved on the rotating pin 2113, and the torsion spring 24 is located between the two supporting bodies 2112, and the two ends of the torsion spring 24 abut against the mounting body 2111 and the limiting member 23 respectively.

[0075] See also Figure 2 and Figure 3 When assembling the limit member 23, first make the limit member 23 abut against the two support bodies 2112, and then use the rotating pin 2113 to penetrate the two support bodies 2112 and the limit member 23. At this time, the limit member 23 is connected to the mounting member 211 under the limiting action of the rotating pin 2113, and at the same time, the limit member 23 is rotatably connected with the rotating pin 2113, so that the limit member 23 can rotate relative to the mounting member 211 with the rotating pin 2113 as the rotation center.

[0076] The receiving member 212 is in the form of an elongated strip and extends in the X-axis direction. The receiving member 212 is used to receive the elastic member 22. The receiving member 212 includes a bottom plate 2121, a first side plate 2122 and two second side plates 2123. The bottom plate 2121 is mounted on the side of the mounting body 2111 facing the fixing member 11. The first side plate 2122 is connected to the bottom plate 2121 and is perpendicular to the bottom plate 2121. The two second side plates 2123 are arranged on the bottom plate 2121 at intervals. Each second side plate 2123 extends in the X-axis direction. The two second side plates 2123 are perpendicular to the bottom plate 2121. The two second side plates 2123 are respectively connected to the two ends of the first side plate 2122. The bottom plate 2121, the first side plate 2122 and the two second side plates 2123 are jointly arranged to form a receiving groove 2124. The elastic member 22 is received in the receiving groove 2124. Since the elastic member 22 is received in the receiving groove 2124 , the receiving groove 2124 at this time plays a protective role for the elastic member 22 .

[0077] See also Figure 2 and Figure 3 When the mounting member 211 slides relative to the fixing member 11 along the positive direction of the X-axis, for example, the mounting member 211 moves to the left, the push portion 122 on the pushing member 12 will extend into the receiving groove 2124 and abut against the elastic member 22. When the push portion 122 slides relative to the receiving member 212, the two second side plates 2123 at this time can guide the push portion 122, thereby guiding the push portion 122 to slide. As the mounting member 211 continues to slide, the push portion 122 will continuously compress the elastic member 22, and the damping and buffering mechanism 100 at this time will buffer the relative movement of the two external objects.

[0078] See also Figure 3 The receiving member 212 further includes a baffle 2125 , which is movably received in the receiving groove 2124 , and one end of the baffle 2125 is connected to one end of the elastic member 22 away from the first side plate 2122 , and the baffle 2125 can slide along the receiving groove 2124 .

[0079] See also Figures 2 to 4 When the base 21 slides to the left relative to the fixing member 11, the push portion 122 on the push member 12 will extend into the receiving groove 2124 and abut against the side of the baffle 2125 away from the first side plate 2122. As the base 21 and the fixing member 11 slide relative to each other, the push portion 122 will continue to press against the baffle 2125 to compress the elastic member 22, so that the damping buffer mechanism 100 can achieve a buffering effect. Compared with the method in which the push portion 122 directly presses against the elastic member 22, the contact area between the push portion 122 and the baffle 2125 is larger than the contact area between the push portion 122 and the elastic member 22, thereby avoiding the push portion 122 and the elastic member 22 from slipping, so that the push portion 122 can stably compress the elastic member 22.

[0080] See also Figures 2 to 4 The limiting member 23 includes a main body 231, a stopper 232 and a rotating body 233. The main body 231 includes a rotating portion 2311 and two connecting portions 2312. The rotating portion 2311 is rotatably connected to the mounting body 2111. The rotating portion 2311 abuts against the abutting member 13 on the side facing the fixing member 11, and is used to rotate relative to the mounting body 2111 under the push of the abutting member 13. The two ends of the torsion spring 24 abut against the rotating portion 2311 and the mounting body 2111 respectively. When the damping and buffering mechanism 100 is not in use, the main body 231 always maintains a state of abutting against the abutting member 13 under the action of the torsion spring 24.

[0081] See also Figure 5 and Figure 6 , the distance d between the stopper 232 and the rotation center of the main body 231 is smaller than the distance D between the pusher 12 and the abutment 13. When the mounting member 211 moves to the left, the main body 231 is parallel to the fixing member 11 under the abutment of the abutment 13. At this time, the pusher 12 and the abutment 13 are respectively located on both sides of the rotation center of the main body 231. Since the main body 231 is in a parallel state, the stopper 232 can be used to block the pusher 12.

[0082] In this embodiment, the two connecting portions 2312 and the rotating portion 2311 are an integrated structure, and the two connecting portions 2312 are both arranged at one end of the rotating portion 2311 close to the pushing member 12, and the two connecting portions 2312 are arranged in parallel and spaced apart to form an avoidance groove 2313 around the rotating portion 2311, and the distance between the two connecting portions 2312 is greater than the width of the receiving member 212.

[0083] See also Figures 2 to 4 In this embodiment, there are two stoppers 232, which are respectively connected to the two connecting portions 2312, and the stoppers 232 are located at one end of the connecting portion 2312 away from the rotating portion 2311. The stoppers 232 are used to resist the side of the pusher 12 away from the resisting portion 13. In this embodiment, please refer to Figure 2 When the fixed component 10 and the sliding component 20 are just assembled together, the damping buffer mechanism 100 is in an unused state, the main body 231 is in an inclined state and the receiving member 212 is located in the avoidance groove 2313, and the two stop bodies 232 are located on both sides of the receiving member 212. Figure 4When the mounting member 211 moves to the left, while the elastic member 22 is squeezed, the rotating portion 2311 rotates counterclockwise relative to the mounting body 2111, the receiving member 212 passes through the avoidance groove 2313, and the main body 231 changes from an inclined state to a state parallel to the fixing member 11. The avoidance groove 2313 is used to avoid the receiving member 212 to avoid interference. Because of the existence of the avoidance groove 2313, the main body 231 can rotate smoothly. In this embodiment, the two stop bodies 232 are respectively in contact with the two sides of the push member 12, so that when the limiting member 23 limits the push member 12, the force on the push member 12 can be uniform.

[0084] See also Figure 3 There are two rotating bodies 233, and the two rotating bodies 233 and the rotating part 2311 are an integrated structure. The two rotating bodies 233 are arranged in parallel and spaced apart. The two rotating bodies 233 are bent toward the mounting member 211 so that the two rotating bodies 233 can respectively abut against the two supporting bodies 2112. The rotating pin 2113 penetrates the two supporting bodies 2112 and the two rotating bodies 233, and the rotating body 233 can rotate relative to the rotating pin 2113, so that the rotating pin 2113 can rotatably connect the rotating part 2311 to the mounting body 2111. Since the main body 231 can be rotatably mounted on the mounting body 2111 only by a rotating pin 2113, the connection structure between the main body 231 and the mounting body 2111 is simple and easy to operate.

[0085] See also Figure 2 , the fixed component 10 and the sliding component 20 are two independent parts, so that the damping and buffering mechanism 100 is a split structure. When the fixed component 10 and the sliding component 20 need to be assembled together, the fixed component 10 and the sliding component 20 can be installed on two objects respectively, and then the two objects are assembled to achieve the purpose of assembling the fixed component 10 and the sliding component 20 together. When encountering a situation where the assembly space is limited, due to space limitations, for the damping and buffering mechanism 100 of the integrated structure, it is inconvenient for the operator to operate in a small space to connect the damping and buffering mechanism 100 with the two objects. Since the damping and buffering mechanism 100 of this embodiment is a split structure, during the assembly process, the operator can easily install the fixed component 10 and the sliding component 20 on the two objects respectively, and finally assemble the two objects to achieve the assembly of the damping and buffering mechanism 100. Therefore, the assembly operation of the damping and buffering mechanism 100 of this embodiment is simple and quick, which provides convenience for the operator.

[0086] See also Figure 1 and Figure 2When the fixed component 10 and the sliding component 20 are assembled together, the damping and buffering mechanism 100 is in an unlocked state (i.e., an unused state). At this time, the main body 231 is in an inclined state, and one end of the main body 231 connected to the stopper 232 abuts against the base 21, while the other end of the main body 231 away from the stopper 232 is away from the base 21. The state of the damping and buffering mechanism 100 is as follows: Figure 2 Taking a sliding door as an example, the sliding door is in an open state at this time.

[0087] When the movable member 300 slides to the left to close the sliding door, the damping buffer mechanism 100 enters the use state. The damping buffer mechanism 100 first enters the buffer state and applies a force to the base 21 to make the base 21 slide relative to the fixed member 11 along the positive direction of the X axis. Figure 2 For example, the base 21 is pulled to slide to the left. At this time, the abutting member 13 moves to the right relative to the base 21. The pushing member 12 on the fixing member 11 compresses the elastic member 22 through the baffle 2125. As the base 21 and the fixing member 11 continue to slide relative to each other, the pushing member 12 continues to compress the elastic member 22. Figure 4 When the pusher 12 starts to compress the elastic member 22, the damping buffer mechanism 100 enters the buffering state. Since the elastic member 22 is continuously compressed, the damping buffer mechanism 100 can buffer two objects sliding relative to each other. While the elastic member 22 is compressed, the abutting member 13 abuts the main body 231 to make the main body 231 rotate counterclockwise relative to the base 21. At this time, the main body 231 drives the stopper 232 to rotate counterclockwise to make the main body 231 rotate to a state parallel to the fixing member 11. At this time, the stopper 232 is located on the side of the pusher 12 away from the abutting member 13. The state of the damping buffer mechanism 100 is as follows: Figure 4 shown.

[0088] See also Figure 5 When the elastic member 22 rebounds and resets, the elastic member 22 at this time will generate a thrust on the first side plate 2122, and the first side plate 2122 will drive the mounting member 211 to move, so that the entire base 21 moves relative to the fixing member 11 along the negative direction of the X-axis, that is, the base 21 slides to the right. During the resetting process of the elastic member 22, the stopper 232 abuts against the side of the pushing member 12 away from the supporting member 13. At this time, the base 21 and the fixing member 11 no longer move relative to each other, and the pushing member 12, the supporting member 13, the limiting member 23, the elastic member 22 and the torsion spring 24 are in a state of force balance, and the base 21 and the fixing member 11 are self-locking. At the same time, the two objects respectively connected to the base 21 and the fixing member 11 are also in a self-locking state. It should be noted that the two objects have not returned to their initial positions. The state of the damping buffer mechanism 100 is as shown in FIG. Figure 5 In this embodiment, the self-locking state of the damping buffer mechanism 100 corresponds to the state where the sliding door is closed.

[0089] See also Figure 7 When the two objects need to be restored to their initial positions, it is only necessary to apply force to the base 21 to break the equilibrium state of the pusher 12, the abutment 13, the stopper 23, the elastic member 22 and the torsion spring 24. First, the base 21 is pushed to the right to deform the stopper 232 (such as Figure 7 As shown in FIG. 2 , as the base 21 is pushed rightward, the stopper 232 moves from the left side of the pusher 12 to the right side of the pusher 12, and the stopper 232 also returns to a state without deformation, and at the same time, the limiter 23 changes from a parallel state to an inclined state, that is, the damping and buffering mechanism 100 changes from a parallel state to an inclined state. Figure 5 The status becomes Figure 2 The damping and buffering mechanism 100 is unlocked when the two objects are in the state in which the base 21 and the fixing member 11 are respectively connected. The two objects are restored to their initial positions. It should be noted that the structure of the stopper 232 shown in the figure does not constitute a limitation. For example, the stopper 232 may be in the form of a sheet, and the stopper 232 may be made of a material with good elasticity so that the stopper 232 will not break during use. In addition, it can be seen from the above process that when the two objects are reset, they need to be unlocked and self-locked to return to the initial position, that is, the elastic force of the elastic member 22 has undergone a process of being gradually released. Since the elastic force of the elastic member 22 is released in stages, the phenomenon of the two objects being damaged due to excessive elastic force of the elastic member 22 can be avoided. In this embodiment, the state in which the sliding door is automatically opened corresponds to the unlocking of the damping and buffering mechanism 100.

[0090] The limiting member 23 further includes a guide body 234, which is connected to the side of the stopper 232 away from the main body 231. The guide body 234 is bent from the stopper 232 to the direction away from the main body 231. Specifically, the bending direction of the guide body 234 is to bend to the side away from the abutting member 13, so that the guide body 234 is in an arc-shaped structure. When the abutting member 13 pushes the main body 231 to rotate relative to the base 21, the main body 231 will change from an inclined state to a parallel state. During the rotation of the main body 231, when the connecting body 121 on the pushing member 12 touches the guide body 234, since the guide body 234 is in an arc-shaped structure, the guide body 234 at this time will guide the connecting body 121 to slide smoothly between the stopper 232 and the abutting member 13, thereby avoiding the phenomenon that the stopper 232 and the pushing member 12 are stuck.

[0091] See also Figures 2 to 4During the use of the damping and buffering mechanism 100, since the main body 231 and the abutting member 13 often slide relative to each other, in order to reduce the wear between the main body 231 and the abutting member 13, the abutting member 13 includes two bearing bodies 131 and a roller 132. The two bearing bodies 131 are spaced apart on the side of the fixing member 11 facing the base 21, and the roller 132 is rotatably connected between the two bearing bodies 131. The specific connection method of the roller 132 is as follows: the roller 132 is located between the two bearing bodies 131, and a positioning pin 133 is provided between the roller 132 and the two bearing bodies 131, and the roller 132 can rotate relative to the positioning pin 133. The roller 132 is used to abut the main body 231. When the base 21 slides relative to the fixing member 11, the roller 132 will push the main body 231 to rotate, so that the stopper 232 on the main body 231 can limit the pusher 12 and self-lock it. Since the roller 132 can rotate relative to the carrier 131, when the roller 132 pushes the main body 231, the roller 132 will roll along the surface of the main body 231. Since the friction force of rolling friction is small, the friction force between the abutting member 13 and the limiting member 23 is small, so that the abutting member 13 and the limiting member 23 are not easy to wear, thereby extending the service life of the damping buffer mechanism 100. In other embodiments, the carrier 131 can directly abut the limiting member 23.

[0092] The working process of the push-pull device 1000 provided in the embodiment of the present application is roughly as follows:

[0093] When the push-pull device 1000 is closed, the movable member 300 slides to the left along the positioning member 200, and the movable member 300 slides with the base 21 relative to the fixed member 11, so that the push member 12 on the fixed member 11 compresses the elastic member 22. At this time, the damping and buffering mechanism 100 buffers the movable member 300, so that the movable member 300 does not collide with the side wall 203 on the left side of the positioning member 200, thereby protecting the movable member 300 and the positioning member 200 from damage. When the elastic member 22 rebounds and resets, under the action of the elastic member 22, the stopper 232 abuts against the pusher 12, and under the limiting action of the stopper 232, the movable member 300 and the positioning member 200 enter self-locking, that is, the sliding door is closed.

[0094] When force is applied to the movable member 300 to break the self-locking of the damping and buffering mechanism 100 , the movable member 300 slides to the right along the positioning member 200 and returns to the initial position, that is, the sliding door is opened.

[0095] During the operation of the push-pull device 1000, the corresponding action process generated by the damping and buffering mechanism 100 is as follows: first, the base 21 is subjected to an external force and slides relative to the fixing member 11. At this time, the supporting member 13 on the fixing member 11 pushes the limiting member 23 to rotate relative to the base 21, so that the limiting member 23 changes from an inclined state to a state parallel to the fixing member 11. At the same time, the pushing portion 122 on the pushing member 12 continuously compresses the elastic member 22. When the elastic member 22 is compressed, the damping and buffering mechanism 100 can buffer two objects that have relative motion.

[0096] When the elastic member 22 rebounds and resets, the elastic member 22 generates a thrust on the first side plate 2122. At this time, the first side plate 2122 pushes the mounting member 211 to slide. When the pushing member 12 abuts against the stop body 232 on the limiting member 23, the base 21 stops moving under the limiting action of the stop body 232. At this time, self-locking is formed between the base 21 and the fixing member 11. When force is applied to the base 21 again to break the balance between the fixing component 10 and the sliding component 20, the fixing component 10 and the sliding component 20 will return to their initial positions.
