Description

Buffer device

Technical Field

The present disclosure relates to a shock absorber, and more particularly to a shock absorber.

Background

When the sliding door is opened too fast, the sliding door is easy to violently impact on a door frame or a wall. A great sound can occur when the sliding door violently hits the doorsill or the wall, and the sliding door is easy to damage. The buffer is arranged to effectively buffer the impact force of the sliding door and stop the sliding door.

But the existing buffer can only realize the impact buffering of the sliding door and can not realize the independent pressing and rebounding of the sliding door.

Disclosure of Invention

The application provides a buffer, can realize initiatively pressing bounce-back.

The buffer includes:

a housing;

a damper including a cylinder disposed within the housing and a damping rod extending from the cylinder;

a buffer comprising a strike key disposed outside the housing, a first magnet disposed within the strike key, and a link extending from the strike key into the housing;

the two ends of the connecting sleeve are respectively sleeved on the connecting rod and the damping rod;

the second magnet is arranged in the shell, positioned on one side of the connecting rod, connected with the shell in a sliding manner and capable of sliding towards the direction close to the connecting rod;

the first elastic piece is arranged on one side of the second magnet, which is far away from the connecting rod, and is used for applying elastic force to the second magnet in the direction close to the connecting rod;

the sliding part comprises a connecting part and a baffle, the connecting part is sleeved on the damping rod, can slide along the damping rod and is positioned between the connecting sleeve and the cylinder body, and the baffle can extend from the connecting part to a position between the connecting rod and the second magnet;

a second elastic member for applying an elastic force to the slider to be away from the cylinder;

the first magnet and the second magnet are provided with the same magnetic poles at the sides close to each other, and the impact key moves towards the direction close to the cylinder body, so that the connecting sleeve can move the baffle away from the position between the connecting rod and the second magnet under the driving of the connecting rod.

Before the impact key is not impacted, the impact key is located at the initial position farthest from the cylinder body, the damping rod extends out of the cylinder body to the limit position, the baffle blocks the second magnet on the side, away from the connecting rod, of the baffle, and the connecting sleeve is separated from the connecting part of the sliding part. When the impact key is impacted, the impact key moves towards the direction of the damper, the impact force borne by the impact key is transmitted to the damping rod through the connecting rod and the connecting sleeve so as to press the damping rod into the cylinder body, and the damper generates resistance which hinders the damping rod to contract in the process that the damping rod contracts into the cylinder body so as to consume the kinetic energy of the component to be buffered. When the kinetic energy of the part to be buffered is consumed, the impact key stops moving, the connecting sleeve moves to a position close to the connecting part of the sliding part, and the baffle still blocks the second magnet on the side, facing away from the connecting rod, of the baffle. At this time, the buffer completes the buffering of the member to be buffered.

When the part to be buffered needs to be separated from the buffer, for example, when the part to be buffered is a sliding door which needs to be closed, only a force is required to be applied to the part to be buffered to press the impact key so that the impact key continues to be close to the cylinder body, the connecting sleeve is driven by the impact key to be close to the cylinder body and abut against the connecting part of the sliding part, and the connecting sleeve continues to be close to the cylinder body after abutting against the sliding part and drives the sliding part to move towards the direction close to the cylinder body. In this process, the second elastic member is compressed while the shutter of the slide member is gradually removed from between the link and the second magnet. When the shutter is completely removed from between the link and the second magnet, the second magnet approaches the link by the elastic force of the first elastic member, so that the first magnet and the second magnet approach each other. And because the sides of the first magnet and the second magnet, which are close to each other, have the same magnetic pole, a repulsion force is arranged between the first magnet and the second magnet, the first magnet moves in the direction away from the cylinder body under the pushing of the repulsion force, meanwhile, the second elastic piece applies a recovery elastic force deviating from the cylinder body to the sliding piece, the repulsion force and the recovery elastic force are transmitted to the impact key to jointly drive the impact key to move in the direction deviating from the cylinder body and recover to the initial position, in the process, the impact key also drives the part to be buffered to rebound rapidly, so that the part to be buffered is separated from the buffer rapidly, and the active pressing rebound of the part to be buffered is realized.

Additional features and advantages of the application will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of the application. Other advantages of the present application may be realized and attained by the instrumentalities and combinations particularly pointed out in the specification and the drawings.

Detailed Description

As shown in fig. 1 and 2, fig. 1 and 2 show the structure of the buffer in the present embodiment. The buffer comprises a shell 1, a damper 3, a buffer 2, a connecting sleeve 4, a second magnet 5, a first elastic element 6, a sliding element 7 and a second elastic element 8.

The housing 1 is of a thin shell structure. The housing 1 includes a case 11 and a back plate 12. The housing 11 includes a first container 111 and a second container 112. The first container 111 is connected to the second container 112. The bottom of the first container 111 is flush with the bottom of the second container 112, and the top plate of the first container 111 is higher than the top plate of the second container 112. The first container 111 and the second container 112 may be in the shape of a bar, and one end of the first container 111 is connected to one end of the second container 112. The back plate 12 is a flat plate, bottom openings are formed at the bottoms of the first box 111 and the second box 112, and the back plate 12 covers the bottom openings of the first box 111 and the second box 112. The back plate 12 and the housing 11 may be connected by screws, for example, three screws 13. The damper 3, the connection sleeve 4, the second magnet 5, the first elastic member 6, and the slider 7 are disposed in the first case 111. As shown in fig. 4, a through hole 100 is formed in a sidewall of the first container 111 adjacent to the second container 112.

As shown in fig. 2, the damper 3 includes a cylinder 31 and a damping rod 32. The cylinder 31 has a cylindrical structure. The damping rod 32 protrudes from one end of the cylinder 31. The damper rod 32 is slidable relative to the cylinder 31 in the axial direction of the cylinder 31. The damper 3 is a one-way damper 3, and the resistance of the damper 3 when contracted is larger than the resistance of the damper 3 when stretched. The cylinder 31 is fixed to the upper portion of the first container 111. The cylinder 31 may be disposed at an end of the first container 111 facing away from the second container 112. The damping rod 32 extends from the cylinder 31 in a direction to approach the second case 112.

As shown in fig. 1 and 2, the buffer member 2 includes a striking pin 21, a bottom cover 24, a first magnet 23, and a link 22. The striking pin 21 is disposed above the second container 112. The outer contour of the striking pin 21 may be configured as a hexahedral structure. As shown in fig. 4, the striking pin 21 is provided with a cavity in which the first magnet 23 is fixed. The first magnet 23 may be a permanent magnet, such as a neodymium iron boron magnet. The bottom of the striker bar 21 has an opening over which a bottom cover 24 can be fitted. The bottom cover 24 and the impact key 21 can be connected by screws. The link 22 is a straight rod, and one end of the link 22 is connected to the striking pin 21. The link 22 and the striker 21 may be of integrally formed construction. The other end of the link 22 passes through the through hole 100 of the first container 111 and extends into the first container 111. The connecting rod 22 and the damping rod 32 are coaxially arranged. One end of the link 22 and one end of the damping rod 32 are close to each other.

The connecting sleeve 4 is of a cylindrical structure. The connection sleeve 4 is disposed in the first case 111. Two ends of the connecting sleeve 4 are respectively sleeved at one end of the connecting rod 22 and one end of the damping rod 32 close to each other. The connecting sleeve 4 is respectively in threaded connection with the connecting rod 22 and the damping rod 32. The outer diameter of the connecting sleeve 4 is larger than the outer diameter of the connecting rod 22 and the outer diameter of the damping rod 32.

A slide 118 is also provided in the first container 111. The slide 118 is disposed at a side of the first container 111 adjacent to the second container 112. The slide 118 extends from the bottom of the first container 111 to the link 22. The second magnet 5 is disposed within the slide 118. The second magnet 5 can slide along the slide 118 to approach and separate from the link 22. The second magnet 5 may be a permanent magnet, such as a neodymium iron boron magnet. The sides of the first magnet 23 and the second magnet 5 that are close to each other have the same magnetic pole. For example, the side of the first magnet 23 adjacent to the second magnet 5 is N-step, and the side of the second magnet 5 adjacent to the first magnet 23 is N-step. The first elastic member 6 is a coil spring. The first elastic member 6 is disposed between the second magnet 5 and the back plate 12, and both ends of the first elastic member 6 abut against the second magnet 5 and the back plate 12, respectively. The first elastic member 6 is in a compressed state, and the first elastic member 6 applies an elastic force to the second magnet 5 in a direction approaching the link 22.

As shown in fig. 3, the slider 7 is disposed in the first container 111. The slider 7 includes a connecting portion 71 and a shutter 72. The connecting portion 71 is connected to one end of the baffle 72. The connecting portion 71 is provided with a through hole 74, the through hole 74 is parallel to the baffle 72, and the diameter of the through hole 74 is smaller than the outer diameter of the connecting sleeve 4. The damper rod 32 is inserted into the through hole 74 with the connecting portion 71 between the cylinder and the joint sleeve 4, and the baffle 72 extends from the lower end of the connecting portion 71 toward the striking pin 21. The length of the shutter 72 is less than the maximum stroke of the strike bar 21. The baffle 72 and the damper rod 32 have a gap therebetween, and the width of the gap is greater than the thickness of the connecting sleeve 4. The side of the baffle 72 near the damping rod 32 may be provided with a bar groove 73, and the bar groove 73 is a straight bar groove and is parallel to the damping rod 32. The cross section of the groove 73 may be circular arc. The slot 73 serves to give way to the nipple 4 so that the nipple 4 cannot come into contact with the baffle 72. The baffle 72 can extend between the second magnet 5 and the link 22, and the second magnet 5 cannot approach the link 22 when abutting against the baffle 72.

The second elastic member 8 may be a coil spring. The second resilient element 8 is in a compressed state. The second elastic member 8 may be sleeved on the damping rod 32. One end of the second elastic member 8 abuts on the connecting portion 71 of the slider 7, and the other end of the second elastic member 8 abuts on the cylinder 31. The second elastic member 8 is for applying an elastic force to the slider 7 in a direction close to the striking pin 21.

The striking pin 21 is for receiving the striking of a member to be cushioned (not shown in the figure). The component to be buffered can be a sliding door of a shower room, and when the sliding door of the shower room is opened to the maximum and needs to be stopped, the sliding door collides with the collision key 21 of the buffer to obtain buffering stop.

As shown in fig. 4, before the striking pin 21 is struck, the striking pin 21 is located at the initial position farthest from the cylinder 31, the damper rod 32 protrudes from the cylinder 31 to the limit position, the baffle 72 blocks the second magnet 5 at the side of the baffle 72 facing away from the connecting rod 22, and the connecting sleeve 4 is separated from the connecting portion 71 of the slider 7. As shown in fig. 5, when the striking rod 21 is struck, the striking rod 21 moves towards the damper 3, the impact force borne by the striking rod 21 is transmitted to the damping rod 32 through the connecting rod 22 and the connecting sleeve 4 to press the damping rod 32 into the cylinder 31, and the damper 3 generates a resistance force which hinders the damping rod 32 from contracting during contraction of the damping rod 32 into the cylinder 31 to consume the kinetic energy of the component to be buffered. As shown in fig. 6, when the kinetic energy of the member to be buffered is used up, the striking pin 21 stops moving, the connecting sleeve 4 moves to a position close to the connecting portion 71 of the sliding member 7, and the baffle 72 still blocks the second magnet 5 on the side of the baffle 72 facing away from the connecting rod 22. At this time, the buffer completes the buffering of the member to be buffered.

When the member to be buffered needs to be separated from the buffer, for example, the member to be buffered is a sliding door which needs to be closed, as shown in fig. 7, only a force needs to be applied to the member to be buffered to press the striking rod 21 so that the striking rod 21 continues to approach the cylinder 31, the connecting sleeve 4 approaches the cylinder 31 under the driving of the striking rod 21 and abuts against the connecting portion 71 of the sliding member 7, and the connecting sleeve 4 continues to approach the cylinder 31 after abutting against the sliding member 7 and can drive the sliding member 7 to move in the direction approaching the cylinder 31. In this process, the second elastic member 8 is compressed while the shutter 72 of the slider 7 is gradually removed from between the link 22 and the second magnet 5. When the shutter 72 is completely removed from between the link 22 and the second magnet 5, the second magnet 5 approaches the link 22 by the elastic force of the first elastic member 6, so that the first magnet 23 and the second magnet 5 approach each other. And because the sides of the first magnet 23 and the second magnet 5, which are close to each other, have the same magnetic pole, a repulsive force is provided between the first magnet 23 and the second magnet 5, the first magnet 23 moves in the direction away from the cylinder 31 under the pushing of the repulsive force, and meanwhile, the second elastic member 8 applies a recovery elastic force away from the cylinder 31 to the sliding member 7, the repulsive force and the recovery elastic force are transmitted to the impact rod 21 to jointly drive the impact rod 21 to move in the direction away from the cylinder 31 and recover to the initial position shown in fig. 1, in the process, the impact rod 21 also drives the component to be buffered to rapidly rebound, so that the component to be buffered is rapidly separated from the buffer, and thus the pressing rebound of the component to be buffered is realized.

In an exemplary embodiment, as shown in fig. 2, the second magnet 5 is further provided with a recess 51, the recess 51 being provided at an end of the second magnet 5 near the link 22. The recess 51 may be provided in the middle of the end of the second magnet 5 near the link 22. The recess 51 has an opening that faces the link 22. The width of the recess 51 is greater than the width of the link 22 so that the recess 51 can receive a portion of the link 22.

After the shutter 72 is removed from between the second magnet 5 and the link 22, the second magnet 5 moves closer to the link 22 until the recess 51 of the second magnet 5 receives a portion of the link 22. Thus, the second magnet 5 can be opposed to the first magnet 23, the repulsive force between the second magnet 5 and the first magnet 23 is stronger, and the repulsive force to be applied to the board member to be buffered is larger.

In an exemplary embodiment, the second magnet 5 is of a substantially wedge-shaped configuration, with the tip of the second magnet 5 facing away from the first spring 6. The side of the second magnet 5 facing away from the cylinder 31 of the damper 3 is perpendicular to the plane of the connecting rod 22. The closer to the first elastic member 6, the greater the width between the side of the second magnet 5 facing the cylinder 31 of the damper 3 and the side of the second magnet 5 facing away from the cylinder 31 of the damper 3.

As shown in fig. 7, during the pressing rebound, the sliding member 7 presses the second magnet 5 toward the side of the cylinder 31 under the action of the elastic force exerted by the second elastic member 8, and since the second magnet 5 has a wedge-shaped structure, the pressing force exerted by the baffle 72 of the sliding member 7 on the second magnet 5 has a component force in the direction toward the first elastic member 6, which is greater than the elastic force exerted by the first elastic member 6 on the second magnet 5, so that the second magnet 5 moves away from the link 22 while the first elastic member 6 is compressed, and the second magnet 5 finally returns to the side of the baffle 72 away from the link 22 to be reset.

In an exemplary embodiment, as shown in fig. 2, the damper further includes two hook members 10 and two third elastic members 9. Both hook members 10 are slidably connected to the second container 112.

As shown in fig. 8, hook 10 comprises a fork 101, a connecting post 107 and two sliding bars 107. Connecting column 107 and slide bar 107 are both connected to fork 101. The fork 101 comprises two jaws 102 and a base 104. Both jaws 102 are disposed on the same side of the base 104 and are spaced apart from each other. Two fingers 102 project from the base 104 away from the base 104. A receiving groove 103 is formed between the two jaws 102. The receiving groove 103 may have a rectangular cross section. The sides of the tops of the two claws 102 facing away from each other may be provided with a chamfer.

The base 104 further has two through holes 105, and the two through holes 105 are respectively located at two ends of the base 104. The two through holes 105 are perpendicular to the extending direction of the two jaws 102. The two sliding rods 107 respectively penetrate through the two through holes 107. Slide bar 107 may be cylindrical. The sliding rod 107 and the through hole 107 can be in interference fit. A connecting stub 107 projects from the base 104 of the fork 101 in a direction away from the pawl 102. A connecting post 107 is provided on the side of the base 104 facing away from the pawl 102.

As shown in fig. 1 and 2, two first guide grooves 113 are formed in the top plate of the second container 112. The first guide groove 113 penetrates the top plate of the second container 112. The two first guide grooves 113 are straight grooves. Both the first guide grooves 113 are parallel to the link 22. Second guide grooves 114 are formed on both opposite side plates of the second container 112. The second guide groove 114 penetrates the side plate. The second guide groove 114 is a bar groove. The second guide groove 114 includes a straight groove 115, a first hook groove 116, and a second hook groove 117. The straight slot 115 is a straight bar parallel to the link 22. The first hook groove 116 and the second hook groove 117 are both arc-shaped. The first hook 116 is connected to the end of the straight slot 115 away from the first box 111, and the second hook 117 is connected to the end of the straight slot 115 close to the first box 111. The first hook groove 116 and the second hook groove 117 extend from both ends of the straight groove 115 to a direction away from the top plate of the second container 112, respectively.

As shown in fig. 10, the guide seat 14 is provided in the second container 112. The guide seat 14 is fixed to the top plate of the second container 112. The guide seat 14 is in the shape of a straight bar. The guide shoe 14 extends in a direction parallel to the link 22. Two gaps are formed between the guide seat 14 and the two side plates of the second box 112, and the two first guide grooves 113 are respectively communicated with the two gaps. The opposite sides of the guide seat 14 are provided with third guide grooves 141. The shape of third guide groove 141 is the same as that of second guide groove 114, and two third guide grooves 141 are aligned with each other with respective second guide grooves 114 adjacent to each other.

As shown in fig. 12, the two hook members 10 are respectively disposed at opposite sides of the guide seat 14. As shown in fig. 5, two ends of the sliding rod 107 of the hook 10 respectively extend into the second guide slot 114 and the third guide slot 141 adjacent to the hook 10, the sliding rod 107 is in clearance fit with the second guide slot 114 and the third guide slot 141, and the two sliding rods 107 of the hook 10 can slide along the second guide slot 114 and the third guide slot 141. Thus, a sliding connection is formed between both hook members 10 and the second container 112.

The forks 101 of the two hook members 10 protrude from the top plate of the second case 112 through the first guide grooves 113, respectively. Two protrusions 241 are further provided on the bottom cover 24, the two protrusions 241 being provided on a side of the bottom cover 24 facing away from the first magnet 23. The two protrusions 241 extend into the receiving grooves 103 of the two forks 101, respectively. When the buffer member 2 moves, the two hook members 10 can be respectively driven to slide by the two protrusions 241.

The third elastic member 9 may be a coil spring. The two third elastic members 9 respectively apply elastic forces to the two hook members 10 in the direction approaching the cylinder 31.

In this embodiment, as shown in fig. 2, the third elastic member 9 includes a first clamping portion 91 and a second clamping portion 92, the first clamping portion 91 and the second clamping portion 92 are disposed at two ends respectively close to the third elastic member 9, and the diameters of the first clamping portion 91 and the second clamping portion 92 are smaller than the diameter of the end of the third elastic member 9.

As shown in fig. 4 and 12, a first locking groove 108 is provided on an end of the connection post 107 of the hook 10 facing away from the shift fork 101. One side of the first box 111 departing from the second box 112 is provided with a hook base 119, and the top end of the hook base 119 is provided with two second slots 1191. The two third elastic members 9 are respectively arranged corresponding to the two hook members 10, and the two third elastic members 9 are also respectively arranged corresponding to the two second locking grooves 1191. As shown in fig. 14, the first locking portion 91 of each third elastic member 9 is locked into the first locking groove 108 of the hook member 10 corresponding to the third elastic member 9, and the second locking portion 92 of each third elastic member 9 is locked into the second locking groove 1191 corresponding to the third elastic member 9. The third elastic element 9 is in a stretched state.

As shown in fig. 4, the damper 3 further includes a fourth elastic member 33 and a piston 34. The piston 34 is disposed in the cylinder 31 and connected to the damping rod 32. The fourth elastic member 33 serves to apply an elastic force directed to one side of the damping rod 32 to the piston 34. The fourth elastic member 33 may be a coil spring. The fourth elastic member 33 is in a compressed state. Both ends of the fourth elastic member 33 abut against the piston 34 and the bottom of the cylinder 31, respectively. The elastic force of the fourth elastic member 33 applied to the piston 34 causes the damping rod 32 to have a tendency to protrude out of the cylinder 31.

When the striking pin 21 is in the initial position, the hook member 10 is located at one end of the second guide groove 114 and the third guide groove 141 facing away from the cylinder 31, one sliding rod 107 of the hook member 10 is hung in the first hook groove 116 of the second guide groove 114, and the elastic force applied by the third elastic member 9 to the connecting column 107 of the hook member 10 causes the hook member 10 to be stably hung in the first hook groove 116. When the component to be buffered collides with the striking pin 21, the striking pin 21 moves in a direction approaching the cylinder 31, the protrusion 241 enters the receiving groove 103 of the shift fork 101 and shifts the shift fork 101 so that the hook 10 is disengaged from the first hook groove 116. After being disengaged from the first hook groove 116, the hook 10 pulls the protrusion 241 toward the cylinder 31 by the elastic force of the third elastic member 9, and moves toward the cylinder 31, while the fourth elastic member 33 in the damper 3 is compressed and charged. The elastic force of the third elastic member 9 to the hook member 10 is gradually reduced as the third elastic member 9 is shortened, and the elastic force of the fourth elastic member 33 to the piston 34 is gradually increased as the fourth elastic member 33 is compressed. When the impact key 21 moves until the connecting sleeve 4 abuts against the connecting part 71 of the sliding part 7, the kinetic energy of the part to be buffered is consumed, the elastic force exerted by the third elastic part 9 and the fourth elastic part 33 is transmitted to the impact key 21 to be counteracted with each other, the stress of the impact key 21 is balanced, and the impact key 21 stops moving.

When the component to be buffered needs to be separated from the buffer, for example, when the component to be buffered is a sliding door which needs to be closed, only a force needs to be applied to the component to be buffered to press the striking rod 21 so that the striking rod 21 continues to approach the cylinder 31, the connecting sleeve 4 approaches the cylinder 31 under the driving of the striking rod 21 and abuts against the connecting part 71 of the sliding member 7, the connecting sleeve 4 continues to approach the cylinder 31 after abutting against the sliding member 7 and can drive the sliding member 7 to move in the direction approaching the cylinder 31, and meanwhile, the striking rod 21 also drives the hook 10 to move in the direction approaching the cylinder 31 through the protrusion 241. In this process, the second elastic member 8, the fourth elastic member 33 are compressed, the third elastic member 9 is extended, and the shutter 72 of the slider 7 is gradually removed from between the link 22 and the second magnet 5. When the shutter 72 is completely removed from between the link 22 and the second magnet 5, the second magnet 5 approaches the first magnet 23 by the elastic force of the first elastic member 6. Since the sides of the first magnet 23 and the second magnet 5 close to each other have the same magnetic pole, the second magnet 5 applies a repulsive force to the first magnet 23 in a direction away from the cylinder 31, meanwhile, the second elastic member 8 applies a restoring elastic force to the slider 7 in the same direction as the repulsive force, the fourth elastic member 33 applies a restoring elastic force to the piston 34 in the same direction as the repulsive force, the third elastic member 9 applies an elastic force to the hook 10 in a direction opposite to the repulsive force, that is, the elastic force is close to the cylinder, and the resultant force of the repulsive force and the two restoring elastic forces is greater than the elastic force applied by the third elastic member 9. Therefore, the repulsive force and the two restoring elastic forces can overcome the elastic force applied by the third elastic member 9 to drive the striking pin 21 to move away from the cylinder 31, so that the striking pin 21 is restored to the original position, and the hook member 10 is driven by the protrusion 241 to be hung on the first hook groove 116 again. The bumping rod 21 also drives the component to be buffered to rebound rapidly in the process, so that the component to be buffered is separated from the buffer rapidly.

In an exemplary embodiment, as shown in fig. 2, the back plate 12 is further provided with a guide rod 121 positioned in the first container 111. The guide rod 121 is a straight rod, and the guide rod 121 may be cylindrical. The guide bar 121 is perpendicular to the link 22. A guide rod 121 is disposed within the slide 118. The guide rod 121 may be disposed on the central axis of the slide 118. As shown in fig. 4, the second magnet 5 is provided with a through hole 52, an axis of the through hole 52 is perpendicular to the link 22, and the guide rod 121 penetrates the through hole 52. The first elastic member 6 is fitted around the guide rod 121.

The guide rod 121 can further restrain the second magnet 5 to slide only in the direction perpendicular to the connecting rod 22, and the guide rod 121 can also restrain the first elastic member 6 to stretch only along the guide rod 121, so as to prevent the first elastic member 6 from falling out from between the back plate 12 and the second magnet 5.
