Description
TECHNICAL FIELD
[0001] The utility model relates to furniture hardware technical field, especially a kind of rebound device, it is applied to the press rebound of opening and closing and folding between the first component and the second component of furniture;Particularly applied to the press rebound of opening and closing and folding between cabinet door and cabinet body, and between drawer and cabinet body. BACKGROUND
[0002] In prior art, in order to make home more concise, beautiful, and maximize the use of space, furniture door or drawer tends to use press rebound design without handle, for example, Chinese patent application No. CN202223010206.1 discloses a rebounder, the ejection force in the ejection process and the force used in the folding process are equal, which is inconvenient to use;And, in the folding process, misoperation may also occur to cause the intended folding, but rebound occurs.
[0003] For example, Chinese patent application No. CN202110567145.X discloses a door closer with door opening and closing bidirectional buffer reset, Chinese patent application No. CN202210163435.2 discloses a micro-motion type cabinet door opener, Chinese patent application No. CN202210870756.6 discloses a door opening press rebounder, and Chinese patent application No. CN202211164143.7 discloses a cabinet door press type rebound door opening device. These types of rebounders solve the rebound problem of cabinet door, and use lever principle to indirectly restore the rebounder to the folded state during the closing process of cabinet door. However, its structure is too complex, difficult to manufacture, and high in production cost. Moreover, these designs mainly target the rebound opening and closing folding between cabinet door and cabinet body, and have poor applicability for the rebound opening and closing folding between drawer and cabinet body, which cannot meet people's needs. In addition, cabinet door or drawer is relatively laborious in the closing folding process, and the use experience is poor. UTILITY MODEL CONTENT
[0004] To solve the technical problems of complex structure of rebounder in prior art and great labor in closing folding process of cabinet door or drawer, the utility model provides a rebound device, comprising:
[0005] The ejection piece includes a folded state and an ejection state. When the first component moves towards the second component to make the second component act on the ejection piece, the ejection piece can switch from the folded state to the ejection state, and the ejection piece can react on the first component and drive the first component to move away from the second component.
[0006] The pressing piece includes a first matching device, and the ejection piece includes a second matching device.
[0007] The pressing member further comprises a first connecting portion for rotatably connecting the pressing member to the first member, and a second connecting portion capable of abutting against the second member, the first cooperating device being linearly spaced apart from the first connecting portion by a distance smaller than the second connecting portion;
[0008] a first elastic member for applying an elastic force to the pressing member to rotate the pressing member about the first connecting portion and to generate a pushing force against the second member when the second connecting portion abuts against the second member; the first cooperating device comprises a third connecting portion capable of being elastically extended or displaced, and / or the second cooperating device comprises a third connecting portion capable of being elastically extended or displaced;
[0009] When the ejecting member is switched from the retracted state to the ejecting state to drive the first member to move away from the second member, the first elastic member drives the pressing member to rotate, so that at least a part of the first cooperating device and / or at least a part of the second cooperating device can drive the third connecting portion to be elastically extended or displaced, and then the first cooperating device can move to between the second member and the second cooperating device beyond the second cooperating device;
[0010] Then, when an external force drives the first member to move towards the second member, at least a part of the first cooperating device and / or at least a part of the second cooperating device can be in contact with the third connecting portion to drive the pressing member to switch the ejecting member from the ejecting state to the retracted state.
[0011] Then, when the second member drives the pressing member to continue to move, the first cooperating device can move beyond the second cooperating device, so that the second cooperating device is located between the second member and the first cooperating device.
[0012] Based on the above technical scheme, the rebound device is applied to the opening and closing of a cabinet door or a drawer of furniture, for example, the first component is a cabinet body, and the second component is a cabinet door; or the first component is a drawer, and the second component is a cabinet body, taking the drawer and the cabinet body as examples, when the drawer is closed, the ejector is in a retracted state, after an external force presses or pushes the drawer panel, the ejector is switched from the retracted state to an ejected state, the ejector can act on the back plate or other parts of the cabinet body and then react on the drawer and drive the drawer to move away from the back plate of the cabinet body, at this time, the first elastic member drives the pressing piece to rotate, and the second connecting part moves relative to the drawer to the position of the back plate of the cabinet body; through the setting of the movable telescopic or displacement of the third connecting part, the first matching device can move to the back plate of the cabinet body and the second matching device, and the problem is solved at low cost with a simple structure.
[0013] Then, when the drawer is closed, the external force pushes the drawer to move close to the back plate of the cabinet body, and the back plate or other parts of the cabinet body can abut against the second connecting part to drive the pressing piece to rotate and enable at least a part of the first matching device and / or at least a part of the second matching device to be in contact with the third connecting part, so that the pressing piece drives the ejector to switch from the ejected state to the retracted state, and since the straight-line distance from the first matching device to the first connecting part is less than the straight-line distance from the second connecting part to the first connecting part, according to the principle of a lever, the external force used when the pressing piece drives the ejector to switch from the ejected state to the retracted state is less than the elastic force of the ejector from the retracted state to the ejected state, so that the drawer is more labor-saving and more flexible during the closing process, and the user experience is improved.
[0014] Then, when the second component drives the pressing piece to continue to move, the first matching device can pass through the second matching device, so that the first matching device and the second matching device are separated, that is, at least a part of the first matching device and / or at least a part of the second matching device can no longer be in contact with the third connecting part, so that the second matching device is located between the second component and the first matching device. The problem is solved at low cost with a simple structure.
[0015] In addition, through the contact connection of at least a part of the first matching device and / or at least a part of the second matching device with the third connecting part, when the cabinet door or the drawer drives the ejector to switch from the ejected state to the retracted state during the closing process, the cabinet door or the drawer can not directly contact the ejector, thereby reducing the risk of damage to the ejector and increasing the service life of the ejector. The rebound device has the advantages of simple structure, easy production, and low manufacturing cost.
[0016] In some embodiments, the first matching device includes a clearance space formed on the pressing piece, and / or the second matching device includes a clearance space formed on the ejector;
[0017] When the first member is driven by an external force to move towards the second member, at least a part of the first matching device and / or the second matching device can abut against the third connecting part to drive the ejector to switch from the ejecting state to the retracting state; then when the second member drives the pressing member to continue moving, the third connecting part can enter the avoiding space to make the first matching device able to pass the second matching device, so that the second matching device is located between the second member and the first matching device.
[0018] For example, the second matching device comprises a third connecting part which can move in an extendable or displaceable manner, and the first matching device comprises an avoiding space formed on the pressing member; when the first member is driven by an external force to move towards the second member, at least a part of the first matching device can abut against the third connecting part to drive the ejector to switch from the ejecting state to the retracting state; then when the second member drives the pressing member to continue moving, the third connecting part can enter the avoiding space to make the first matching device able to pass the second matching device, so that the second matching device is located between the second member and the first matching device. When the first member moves towards the second member, the pressing member rotates with the movement of the first member, and a part of the pressing rod can push the third connecting part to make the ejector switch from the ejecting state to the retracting state; and after the ejector switches to the retracting state, the third connecting part can pass through the avoiding space to make the pressing member successfully pass the third connecting part, so that the second matching device is located between the second member and the first matching device; then, when the first member is pressed to make the ejector switch from the retracting state to the ejecting state, the second matching position is located between the first matching position and the second member, so that the movement of the ejector is not affected by the pressing rod when the ejector is ejected, and the movement of the first member is smoother. The rotation of the pressing member relative to the first member and / or the ejector is used to make the first matching device and the second matching device be able to be dislocated and separated when the pressing member rotates to a specific position, which is a clever design to solve the problem with a simple structure and low cost. In addition, when the first matching device comprises a third connecting part which can move in an extendable or displaceable manner, and the second matching device comprises an avoiding space formed on the pressing member, the matching principle is the same as the above-mentioned scheme, which is not described here.
[0019] It should be noted that the avoiding space is only one way for the first matching device and the second matching device to be dislocated and separated, and the present patent is not limited to this way, for example, other components can also be used to abut against the first matching device and / or the second matching device to make the first matching device be dislocated and separated from the second matching device at a specific position.
[0020] In some embodiments, at least one side of the avoiding space is an arc surface or an inclined surface, so that the separation of the first and second matching devices is more smooth.
[0021] In some embodiments, the third connecting part is connected with a third elastic member; the third connecting part is formed with a first surface, which is an inclined surface or an arc surface.
[0022] When the second matching device is located between the second member and the first matching device and the first member moves away from the second member, at least a part of the first matching device can act on the first surface of the second matching device and make the third elastic member of the second matching device deform, so that the first matching device can pass through the third connecting part of the second matching device and be located between the second member and the second matching device. After the first matching device passes through the first surface, the third elastic member can drive the third connecting part of the second matching device to restore to the original state; and / or,
[0023] When the second matching device is located between the second member and the first matching device and the first member moves away from the second member, at least a part of the second matching device can act on the first surface of the first matching device and make the third elastic member of the first matching device deform, so that the second matching device can pass through the third connecting part of the first matching device and be located between the second member and the first matching device. After the second matching device passes through the first surface, the third elastic member can drive the third connecting part of the second matching device to restore to the original state. The inclined surface or arc surface can convert the horizontal thrust into vertical pressure. The pressure member 1 can facilitate the reset of the ejecting member 3, and the structure is ingenious and simple, which solves the problem at low cost.
[0024] In some embodiments, the first elastic member includes a torsion spring, at least a part of the pressure member passes through the torsion spring and is rotationally connected with the first member, the torsion spring can exert a spring force on the pressure member to generate a thrust on the second member when the pressure member contacts with the second member; and / or the torsion spring can exert a spring force on the pressure member, so that at least a part of the first matching device and / or at least a part of the second matching device can drive the third connecting part to be activated to stretch or displace, and then the first matching device can move to the second member and the second matching device.
[0025] In some embodiments, at least one limiting part is further included to limit the rotation range of the pressing piece relative to the first member. In at least one of the embodiments, the first cooperation device can be moved beyond the second cooperation device to a first time between the second member and the second cooperation device, and the pressing piece stops rotating so that the first cooperation device and / or the second cooperation device can be in a state of cooperation contact connection or close to cooperation contact connection with the third connecting part; when the second member moves from a position far away from the pressing piece to the pressing piece and collides with the pressing piece, because the first cooperation device and / or the second cooperation device can be in a state of cooperation contact connection or close to cooperation contact connection with the third connecting part, the damage of the first cooperation device and / or the second cooperation device and the third connecting part can be minimized, the service life is increased, and the user experience is better.
[0026] In some embodiments, the second connecting part is formed with a rolling part to move on the second member in a rolling manner. The friction between the rolling part and the second member is reduced, the furniture member is more silent during opening and closing, the damage of the second member when colliding with the second connecting part is reduced, and the service life is increased.
[0027] In some embodiments, a reciprocating movement mechanism is further included to smoothly switch the ejecting piece between the retracted state and the ejected state.
[0028] In some embodiments, the reciprocating movement mechanism includes a first abutting part, a first guide slot, and a fourth elastic piece, the first guide slot includes a first retracted section and a first ejected section, the ejecting piece includes a first clamping part, and the first clamping part is arranged in the first guide slot.
[0029] When at least a part of the first cooperation device and / or at least a part of the second cooperation device is in cooperation contact connection with the third connecting part, and the ejecting piece is switched from the ejected state to the retracted state, the first clamping part falls into the first retracted section, the first cooperation device passes through the second cooperation device, the ejecting piece compresses the fourth elastic piece, the first clamping part abuts against the first abutting part, and the ejecting piece enters the retracted state.
[0030] Then, when the first member directly acts on the ejecting piece in a direction close to the second member, the first clamping part can enter the first ejected section and disengage from the first abutting part, so that the ejecting piece can act on the second member under the driving of the fourth elastic piece and can counteract to drive the first member to move away from the second member.
[0031] In some embodiments, the reciprocating movement mechanism comprises a second clamping portion and a fourth elastic member, the ejecting member comprises a second abutting portion and a second guide slot, the second guide slot comprises a second retracted section and a second ejecting section, the second clamping portion is arranged in the second guide slot;
[0032] When the second abutting portion abuts on the second clamping portion and switches the ejecting member from the ejecting state to the retracted state, the second clamping portion falls into the second retracted section, the first matching device passes the second matching device, the ejecting member compresses the fourth elastic member, and the second clamping portion abuts on the second abutting portion to make the ejecting member enter the retracted state.
[0033] Then, when the first member directly acts on the ejecting member in the direction approaching the second member, the second clamping portion can enter the second ejecting section and disengage from the second abutting portion, so that the ejecting member can act on the second member under the driving of the fourth elastic member and can react to drive the first member to move away from the second member.
[0034] In some embodiments, the ejecting member is connected with an adjusting portion, when the ejecting member is in the retracted state and the second member continues to approach the first member, the adjusting portion is used to adjust the relative position between the ejecting member and the second member. To facilitate the rebound.
[0035] In some embodiments, a buffer assembly is included, when the first matching device moves away from the second member in the direction of the second matching device and passes the second matching device, the buffer assembly is used to make the first member slowly move in the direction approaching the second member. After the ejecting member returns to the retracted state, the first member can continue to retract and reset relative to the second member in a buffered manner, which facilitates the use of furniture members by users, while being more silent and having a better experience. On the basis of the rebounding device, the rebounding and buffering function furniture members are completed with a simple structure, and the problem is solved at a low cost.
[0036] In some embodiments, a second elastic member is included, when the first matching device contacts and matches with the first matching device and drives the ejecting member to switch from the ejecting state to the retracted state, the second elastic member can drive the second member to move in the direction approaching the first member; at this time, the force of the second elastic member driving the second member to move in the direction approaching the first member is greater than the reaction force of the first elastic member and the resistance of the buffer assembly.
[0037] In some embodiments, the pressing member comprises a first swing arm and a second swing arm connected together, the second connecting portion is located on the second swing arm, and the first matching device is located on the second swing arm.
[0038] In some embodiments, the rebound device further comprises a mounting plate for being fixed on the first member or the second member, a part of the pressing member is pivotally connected to the mounting plate; and / or, the ejecting member is located on the mounting plate; and / or, the first elastic member is located on the mounting plate; and / or, at least a part of the buffer assembly is located on the mounting plate. In this way, the rebound device is more convenient to be installed on the members, and the structure is more stable and firm.
[0039] In some embodiments, at least two adjusting grooves are formed on the mounting plate, and the adjusting grooves are used to adjust the distance between the rebound device and the first member or the second member. BRIEF DESCRIPTION OF DRAWINGS

When the first component 100 or the second component 200 is fixed, when the external force acts on one of the first component 100 and the second component 200, the external force can act on the other of the first component 100 or the second component 200, for example, when the second component 200 is fixed, the force acting on the second component 200 can act on the first component 100, so that the first component 100 and the second component 200 are relatively separated.
[0083] For example, the first component 100 of the embodiment can be a drawer, and the second component 200 can be the back plate or other parts of the cabinet body; for example, the first connecting part 15 rotatably installs the pressing piece 1 on the drawer, the ejecting piece 3 is also installed on the drawer, the second connecting part 16 of the pressing piece 1 is connected or abuts or approaches abuts to the back plate of the cabinet body, when the ejecting piece 3 is in the folding state, the external force drives the drawer to move towards the direction close to the back plate of the cabinet body, after the ejecting piece 3 abuts to the back plate of the cabinet body, the ejecting piece 3 is switched from the folding state to the ejecting state, the ejecting piece 3 generates a pushing force on the back plate of the cabinet body, since the back plate of the cabinet body is fixed, the pushing force acts on the drawer and makes the drawer and the back plate of the cabinet body relatively separated, so that the drawer is in the relatively open state.
[0084] For example, the first component 100 of the embodiment can be a drawer, and the second component 200 can be the back plate or other parts of the cabinet body; for example, the first connecting part 15 rotatably installs the pressing piece 1 on the drawer, the ejecting piece 3 is also installed on the drawer, the second connecting part 16 of the pressing piece 1 is connected or abuts or approaches abuts to the back plate of the cabinet body, when the ejecting piece 3 is in the folding state, the external force drives the drawer to move towards the direction close to the back plate of the cabinet body, after the ejecting piece 3 abuts to the back plate of the cabinet body, the ejecting piece 3 is switched from the folding state to the ejecting state, the ejecting piece 3 generates a pushing force on the back plate of the cabinet body, since the back plate of the cabinet body is fixed, the pushing force acts on the drawer and makes the drawer and the back plate of the cabinet body relatively separated, so that the drawer is in the relatively open state.
[0085] When the ejector 3 is in the retracted state, the first case is the normal use state: the first member 100 and the second member 200 are close to each other (the door or drawer is closed), the second member 200 and the ejector 3 can be in direct contact or close contact, for example, there is a gap between the second member 200 and the end of the ejector 3; the second case is the abnormal use state, that is, the first member 100 and the second member 200 can be in a state of moving away (the door or drawer is opened); no matter which case, as long as the external force drives the first member 100 to move towards the second member 200, and can drive the ejector 3 to abut against the second member 200, so that the ejector 3 is gradually switched from the retracted state to the ejected state after abutting against the second member 200, the ejector 3 can push the second member 200 to move (or in other words, the first member 100 is pushed to move in reaction), so that the first member 100 and the second member 200 are relatively separated, so that the furniture is in an open state.
[0086] The first connecting part 15 can be a rotating shaft or a ball or other rotating body structure, and a part of the pressing piece 1 is rotatably arranged on the first member 100 through the first connecting part 15. Wherein, the pressing piece 1 can be directly rotatable with the first member 100 through the first connecting part 15, or the pressing piece 1 can be rotatably connected with the box body or the shell or the mounting plate 20 first, and then the box body or the shell or the mounting plate 20 is fixed on the first member 100, so that the pressing piece 1 is indirectly rotatable with the first member 100.
[0087] The second connecting part 16 can be one end of the pressing piece 1, or a part of the pressing piece 1, or a component mounted on the pressing piece 1.
[0088] The shape or structure of the third connecting part 311 is not limited in the embodiment of the utility model, and the activity extension or displacement direction of the third connecting part 311 is not limited in the embodiment of the utility model, for example, the third connecting part 311 can be a block or a column, for example, the third connecting part 311 can be extended or displaced in the up-down direction or the left-right direction or the front-back direction relative to the pressing piece 1, and / or the third connecting part 311 can be extended or displaced in the up-down direction or the left-right direction or the front-back direction relative to the ejector 3.
[0089] The linear distance from the first matching device 13 to the first connecting part 15 can refer to the linear distance from the part of the first matching device 13 in contact with the second matching device 31 when the first matching device 13 and the second matching device 31 are in contact and connected to drive the pop-up piece 3 to switch from the pop-up state to the retracted state to the first connecting part 15, and the distance is less than the linear distance from the second connecting part 16 to the first connecting part 15. When the external force pushes the first member 100 to approach the second member 200, the second member 200 drives the pressing piece 1 to rotate around the first connecting part 15 through the second connecting part 16. Since the linear distance from the second connecting part 16 to the first connecting part 15 is greater than the distance from the first matching device 13 to the first connecting part 15, according to the principle of leverage, the pushing force of the external force acting on the first member 100 to switch the pop-up piece 3 from the pop-up state to the retracted state is less than the force of the pop-up piece 3 acting on the first member 100 when the pop-up piece 3 switches from the retracted state to the pop-up state, so that the process of pushing the first member 100 to approach the second member 200 is more labor-saving and more flexible, and the user experience is improved.
[0090] In some embodiments, the second connecting part 16 is in contact with the back plate of the cabinet body. When the external force drives the first member 100 to move towards the second member 200 such as the back plate of the cabinet body, it can drive the pop-up piece 3 to move and abut against the back plate of the cabinet body, so that the pop-up piece 3 gradually switches from the retracted state to the pop-up state after abutting against the back plate of the cabinet body; at this moment when the pop-up piece 3 abuts against the back plate of the cabinet body, the second matching device 31 is located between the first matching device 13 and the back plate of the cabinet body.
[0091] With the ejector 3 gradually switching from the retracted state to the ejecting state and can be set enough elastic force to push the drawer to continue moving away from the backboard of the cabinet to the direction of the drawer completely open or close to completely open. In this process, it can be set when the drawer moves to the backboard of the cabinet and the ejector 3 is separated by a distance, the pressure piece 1 rotates to the first matching device 13 and the second matching device 31 under the action of the first elastic piece 2. The first matching device 13 can move to the backboard of the cabinet and the second matching device 31 between through the flexible and movable or displacement setting of the third connecting part 311 on the first matching device 13 and / or the second matching device 31. In this process, the second connecting part 16 can be always close to the backboard of the cabinet under the action of the first elastic piece 2. In the case of abnormal use, the user may not stop applying external force after the ejector 3 and the backboard of the cabinet abut during the process of the ejector 3 switching from the retracted state to the ejecting state after the ejector 3 and the backboard of the cabinet abut. Instead, the user applies external force to the drawer during the process of the ejector 3 switching from the retracted state to the ejecting state after the ejector 3 and the backboard of the cabinet abut. As a result, when the drawer stops, the second matching device 31 is still located between the first matching device 13 and the backboard of the cabinet. In this case, the user can manually pull open the drawer to make the first matching device 13 move to the backboard of the cabinet and the second matching device 31 between, or the user can press the closed drawer to make the backboard of the cabinet directly abut the ejector 3 to make the ejector 3 switch from the ejecting state to the retracted state. This design has high fault tolerance and will not cause additional damage to the device in the case of abnormal use.
[0092] In the normal use, when the drawer is pushed by the external force from the open state to the closed state, that is, the drawer is driven by the external force to move towards the backboard of the cabinet, the pressing piece 1 is rotated to the position where the first matching device 13 and the second matching device 31 are in contact under the action of the backboard of the cabinet through the third connecting part 311. At this time, the first matching device 13 and the third connecting part 311 on the second matching device 31 can be in contact, or the second matching device 31 and the third connecting part 311 on the first matching device 13 can be in contact, or the third connecting part 311 on the first matching device 13 and the third connecting part 311 on the second matching device 31 can be in contact. The external force is set to be large enough to drive the pressing piece 1 to drive the ejecting piece 3 from the ejecting state to the folding state. In the abnormal case, that is, the external force is not large enough to drive the pressing piece 1 to drive the ejecting piece 3 from the ejecting state to the folding state, the elastic force of the ejecting piece 3 acts on the first matching device 13 through the second matching device 31 to make the ejecting piece 3 rebound to the backboard of the cabinet through the second connecting part 16, so that the drawer moves to the open state. In this case, the user only needs to apply a large enough external force to the drawer. Then, the backboard of the cabinet continues to drive the pressing piece 1 to move, and the first matching device 13 can pass through the second matching device 31, so that the first matching device 13 and the second matching device 31 are separated, that is, at least a part of the first matching device 13 and / or at least a part of the second matching device 31 can no longer be in contact with the third connecting part 311, so that the second matching device 31 is located between the second member 200 and the first matching device 13, and the drawer can be driven to the closed state.
[0093] In addition, in the abnormal use, when the drawer is in the closed state, if the user directly pulls the drawer open, after using the drawer, the drawer can be directly closed, that is, in this case, the function of the rebound device 10 is not used, and therefore, the abnormal use does not damage the furniture and the rebound device 10, and the design has high fault tolerance.
[0094] In addition, by the at least a part of the first matching device 13 and / or the at least a part of the second matching device 31 being in contact with the third connecting part 311, when the drawer drives the ejecting piece 3 from the ejecting state to the folding state during the closing process, the backboard of the cabinet can not directly contact the ejecting piece 3, thereby reducing the risk of damage to the ejecting piece 3 and increasing the service life of the ejecting piece 3. The rebound device 10 of the utility model has simple structure, easy production and low manufacturing cost.
[0095] In some embodiments, the first cooperating device 13 comprises a clearance space 131 formed on the presser 1, and / or the second cooperating device 31 comprises a clearance space 131 formed on the ejector 3; when the first member 100 is driven by an external force to move towards the second member 200, at least a part of the first cooperating device 13 and / or the second cooperating device 31 can abut against the third connecting portion 311 to drive the ejector 3 to switch from the ejecting state to the folding state; then when the second member 200 drives the presser 1 to continue moving, the third connecting portion 311 can enter the clearance space 131 to enable the first cooperating device 13 to pass the second cooperating device 31, so that the second cooperating device 31 is located between the second member 200 and the first cooperating device 13. The clearance space 131 can be a groove or a notch or a slot structure. Among them, the clearance space 131 and the third connecting portion 311 are opposite, for example, the first cooperating device 13 can comprise the clearance space 131, and the second cooperating device 31 can comprise the third connecting portion 311; for another example, the second cooperating device 31 can comprise the clearance space 131, and the first cooperating device 13 can comprise the third connecting portion 311; for another example, the first cooperating device 13 and the second cooperating device 31 each have the third connecting portion 311, when the presser 1 rotates to a certain position, the third connecting portion 311 of the first cooperating device 13 and the third connecting portion 311 of the second cooperating device 31 can be staggered to form the clearance space 131. Take an example: for example, the second cooperating device 31 comprises a third connecting portion 311 which can be movable and telescopic or displaced, and the first cooperating device 13 comprises a clearance space 131 formed on the presser 1; when the first member 100 is driven by an external force to move towards the second member 200, such as the back plate of the cabinet body, at least a part of the first cooperating device 13 can abut against the third connecting portion 311 to drive the ejector 3 to switch from the ejecting state to the folding state; then when the back plate of the cabinet body drives the presser 1 to continue moving, the third connecting portion 311 can enter the clearance space 131 to enable the first cooperating device 13 to pass the second cooperating device 31, so that the second cooperating device 31 is located between the second member 200 and the first cooperating device 13. Referring to Figures 22-25When the first component 100, such as a drawer, moves towards the second component 200, such as a cabinet backboard, the pressing piece 1 rotates with the movement of the first component 100, and a part of the pressing piece 1 can push the third connecting part 311 to switch the ejecting piece 3 from the ejecting state to the retracting state. After the third connecting part 311 passes through the avoiding space 131, the pressing piece 1 successfully passes the third connecting part 311, and the second cooperating device 31 is located between the second component 200 and the first cooperating device 13. Then, when the drawer is pressed to switch the ejecting piece 3 from the retracting state to the ejecting state, the second cooperating position is located between the first cooperating position and the cabinet backboard, so that the movement of the ejecting piece 3 is not affected by the pressing rod when the ejecting piece 3 is ejected, and the movement of the drawer is smoother. The rotation of the pressing piece 1 relative to the drawer and / or the ejecting piece 3 enables the first cooperating device 13 and the second cooperating device 31 to be disengaged when the pressing piece 1 rotates to a specific position, which is a clever design that solves the problem at low cost with a simple structure. In addition, the cooperating principles of the other two cases are the same as the above-mentioned scheme, and are not described here.
[0096] In some embodiments, at least one side of the avoiding space 131 is an arc surface or an inclined surface, so that the disengagement of the first cooperating device 13 and the second cooperating device 31 is smoother. In particular, when the side of the avoiding space 131 is an arc surface, stress concentration can be avoided, the risk of wear of the pressing piece 1 is reduced, and the service life of the pressing piece 1 is prolonged.
[0097] It should be noted that the setting of the avoidance space 131 is only one way for the first cooperating device 13 and the second cooperating device 31 to be dislocated and separated, and the patent does not limit to this way. For example, other components can also be set to abut against the first cooperating device 13 and / or the second cooperating device 31 when the pressing piece 1 is rotated to a specific position, so as to dislocate and separate the first cooperating device 13 and the second cooperating device 31 at the specific position. For example, the pop-up piece 3 further comprises a driving part for driving the third connecting part 311 to be actively extended or retracted, and the driving part is, for example, a reverse buckle or a hook. When an external force drives the first component 100 to move towards the second component 200, at least a part of the first cooperating device 13 can abut against the third connecting part 311, so as to drive the pop-up piece 3 to switch from the pop-up state to the folding state. At least a part of the first cooperating device 13 acts on the driving part, so that the driving part drives the third connecting part 311 to retract or displace, so that the first cooperating device 13 can pass through the third connecting part 311, that is, the pressing piece 1 successfully passes through the third connecting part 311, and the second cooperating device 31 is located between the second component 200 and the first cooperating device 13. For another example, the pop-up piece 3 further comprises a driving part for driving the first cooperating device 13 and / or the second cooperating device 31 at a specific position, and the driving part is, for example, a reverse buckle or a hook. When an external force drives the first component 100 to move towards the second component 200, at least a part of the first cooperating device 13 can abut against the second cooperating device 31, so as to drive the pop-up piece 3 to switch from the pop-up state to the folding state. After the driving part acts on the first cooperating device 13 and / or the second cooperating device 31, the first cooperating device 13 and the second cooperating device 31 are dislocated and separated, so that the first cooperating device 13 can pass through the second cooperating device 31, and the second cooperating device 31 is located between the second component 200 and the first cooperating device 13. The cooperation principles of the remaining cases are similar to the above-mentioned scheme ideas, as long as the first cooperating device 13 and the second cooperating device 31 can be dislocated and separated at a specific position, which will not be described herein.
[0098] In some embodiments, the third connecting portion 311 is connected with a third elastic member 312; the third connecting portion 311 is formed with a first surface 313, which can be an inclined surface or an arc surface; when the second cooperating device 31 is located between the second component 200 and the first cooperating device 13 and the first component 100 moves away from the second component 200, at least a part of the first cooperating device 13 can act on the first surface 313 of the second cooperating device 31 and make the third elastic member 312 of the second cooperating device 31 deform so that the first cooperating device 13 can pass through the third connecting portion 311 of the second cooperating device 31 and be located between the second component 200 and the second cooperating device 31; after the first cooperating device 13 passes through the first surface 313, the third elastic member 312 can drive the third connecting portion 311 of the second cooperating device 31 to restore to the original state. As shown in Figure 25 when the first component 100 is pressed to switch the ejecting member 3 from the retracted state to the ejecting state, the second cooperating position is located between the first cooperating position and the second component 200, so that the movement of the ejecting member 3 is not affected by the pressing member 1 when the ejecting member 3 is ejected, the first cooperating device 13 is driven by the first elastic member 2 to move to contact the first surface 313; since the first surface 313 is an inclined surface or an arc surface, the first elastic member 2 is configured to exert sufficient elastic force on the pressing member 1 to convert the horizontal thrust of the first cooperating device 13 on the third connecting portion 311 into vertical pressure, so that the first cooperating device 13 can gradually press down the third connecting portion 311 during movement until the first cooperating device 13 completely passes through the third connecting portion 311, and then the third elastic member 312 pushes the third connecting portion 311 upward to ensure that when the first component 100 moves toward the second component 200, the first cooperating device 13 can contact and cooperate with the second cooperating device 31 to drive the ejecting member 3 to switch from the ejecting state to the retracted state. In this embodiment, the cooperation of the third elastic member 312 and the inclined surface or the arc surface can make the third connecting portion 311 more smoothly extend and retract, so that when the first component 100 moves away from the second component 200, the first cooperating device 13 can smoothly pass through the second cooperating device 31, so that when the first component 100 moves away from the second component 200, the first component 100 will not be stuck, and the structure is simple and the manufacturing cost is low.
[0099] In some embodiments, when the second engaging device 31 is located between the second member 200 and the first engaging device 13 and the first member 100 moves in a direction away from the second member 200, at least a part of the second engaging device 31 can act on the first surface 313 of the first engaging device 13 and deform the third elastic member 312 of the first engaging device 13 to enable the second engaging device 31 to pass over the third connecting portion 311 of the first engaging device 13, and the first engaging device 13 is located between the second member 200 and the second engaging device 31. After the second engaging device 31 passes over the first surface 313, the third elastic member 312 can drive the third connecting portion 311 of the second engaging device 31 to return to its original state. Alternatively, there is a case that the first engaging device 13 has the first surface 313, and the second engaging device 31 also has the first surface 313. The working principle is combined with the above two embodiments, which will not be described here.
[0100] In some embodiments, the first elastic member 2 includes a torsion spring, and at least a part of the pressing member 1 can pass through the torsion spring and be rotationally connected with the first member 100. The torsion spring can apply an elastic force to the pressing member 1 to generate a pushing force on the second member 200 when the pressing member 1 contacts the second member 200; and / or the torsion spring can apply an elastic force to the pressing member 1 to enable at least a part of the first engaging device 13 and / or at least a part of the second engaging device 31 to drive the third connecting portion 311 to be activated to stretch or displace, and then the first engaging device 13 can move to the second member 200 and the second engaging device 31. The torsion spring can be connected at the position of the first connecting portion 15. When the first member 100 and the second member 200 relatively approach, the torsion spring can apply an elastic force to the pressing member 1 to generate a trend of relatively separating the first member 100 and the second member 200, so that the second connecting portion 16 keeps in contact with the second member 200; the torsion spring is set to have enough force to enable at least a part of the first engaging device 13 and / or at least a part of the second engaging device 31 to drive the third connecting portion 311 to be activated to stretch or displace. In other embodiments, the first elastic member 2 can also be other elastic objects.
[0101] In some embodiments, the utility model embodiment still includes at least one limit part 5, limit part 5 is used to limit the rotation range of pressure piece 1 relative to first component 100, limit part 5 is for example protrusion or bump structure, limit part 5 can be on first component 100 or rebound device 10, or limit part 5 is the elasticity of first elastic piece 2 Limit, not limited here. Limit part 5 is used to be able to limit the rotation range of pressure piece 1 around first connecting part 15, for example, in at least one of the embodiments, it can be that first cooperation device 13 just moves to the first time between second component 200 and second cooperation device 31 after passing through second cooperation device 31, limit part 5 makes pressure piece 1 stop continuing to rotate, so that first cooperation device 13 and / or second cooperation device 31 can be in the state of cooperation contact connection or close to cooperation contact connection with third connecting part 311;When second component 200 moves from relatively far away from pressure piece 1 to pressure piece 1 and collides with pressure piece 1, because first cooperation device 13 and / or second cooperation device 31 can be in the state of cooperation contact connection or close to cooperation contact connection with third connecting part 311, the damage caused by the collision of first cooperation device 13 and / or second cooperation device 31 and third connecting part 311 can be minimized, the service life is increased, and the user's experience is better.
[0102] In some embodiments, second connecting part 16 is formed with rolling part 14, and rolling part 14 is used to move on second component 200 in a rolling manner. Rolling part 14 is rotatably arranged on pressure piece 1, so that the contact between pressure piece 1 and second component 200 is rolling contact, the rolling manner reduces the friction between rolling part 14 and second component 200, makes the furniture component more silent during opening and closing, and reduces the damage that may be caused by the collision between second component 200 and second connecting part 16, and prolongs the service life.
[0103] In some embodiments, the rebound device 10 of the utility model embodiment further includes a reciprocating movement mechanism 4, which is used to smoothly switch the ejector 3 between the collapsed state and the ejected state. When the ejector 3 is in the collapsed state, the reciprocating movement mechanism 4 keeps the ejector 3 in the collapsed state.
[0104] In some embodiments, the reciprocating movement mechanism 4 comprises a first abutting portion 41, a first guide slot 42, and a fourth elastic member 43, the first guide slot 42 comprises a first retracted section 421 and a first ejected section 422, the ejecting member 3 comprises a first clamping portion 32, the first clamping portion 32 is arranged in the first guide slot 42; when at least a part of the first cooperating device 13 and / or at least a part of the second cooperating device 31 is in contact with the third connecting portion 311, and the ejecting member 3 is switched from the ejected state to the retracted state, the first clamping portion 32 falls into the first retracted section 421, the first cooperating device 13 passes the second cooperating device 31, the ejecting member 3 compresses the fourth elastic member 43, and the first clamping portion 32 abuts against the first abutting portion 41, so that the ejecting member 3 enters the retracted state; then, when the first member 100 directly acts on the ejecting member 3 in the direction approaching the second member 200, the first clamping portion 32 can enter the first ejected section 422 and disengage from the first abutting portion 41, so that the ejecting member 3 can act on the second member 200 under the action of the fourth elastic member 43 and can drive the first member 100 to move in the direction away from the second member 200. For example, the first abutting portion 41 has a protruding structure, the first abutting portion 41 is arranged in the first guide slot 42, and the first guide slot 42 forms the first retracted section 421 and the first ejected section 422 through the first abutting portion 41. The first clamping portion 32 can have a hook or buckle structure, and when the ejecting member 3 is in the retracted state, the first clamping portion 32 abuts against the first abutting portion 41, so that the ejecting member 3 can remain in the retracted state. When the ejecting member 3 is switched from the retracted state to the ejected state, the first clamping portion 32 disengages from the first abutting portion 41, so that the ejecting member 3 is switched to the ejected state. Thus, the ejecting member 3 can be smoothly retracted and extended.
[0105] In some other embodiments, the reciprocating movement mechanism 4 comprises a second clamping portion and a fourth elastic member 43, the ejecting member 3 comprises a second abutting portion and a second guide slot, the second guide slot comprises a second retracted section and a second ejected section, and the second clamping portion is arranged in the second guide slot; when the second abutting portion abuts on the second clamping portion and the ejecting member 3 is switched from the ejected state to the retracted state, the second clamping portion falls into the second retracted section, the first cooperating device 13 passes the second cooperating device 31, the ejecting member 3 compresses the fourth elastic member 43, and the second clamping portion abuts against the second abutting portion, so that the ejecting member 3 enters the retracted state; then, when the first member 100 directly acts on the ejecting member 3 in the direction approaching the second member 200, the second clamping portion can enter the second ejected section and disengage from the second abutting portion, so that the ejecting member 3 can act on the second member 200 under the action of the fourth elastic member 43 and can drive the first member 100 to move in the direction away from the second member 200. The movement principle is described above, and the detailed description is omitted here.
[0106] In some embodiments, the ejector 3 is connected with an adjusting part 33, when the ejector 3 is in the collapsed state and the second member 200 continues to approach the first member 100, the adjusting part 33 is used to adjust the relative position between the ejector 3 and the second member 200. For example, the adjusting part 33 is arranged between the ejector 3 and the second member 200, the adjusting part 33 and the ejector 3 can be connected through a threaded connection or a sliding telescopic structure, by adjusting the distance between the ejector 3 and the second member 200 through the adjusting part 33, the adjusting part 33 of the ejector 3 can be made to abut or approach to abut the second member 200, to facilitate the pressing and rebounding.
[0107] In some embodiments, a buffer assembly is included, when the first cooperating device 13 moves away from the second cooperating device 31 in the direction away from the second member 200 and passes the second cooperating device 31, the buffer assembly is used to enable the first member 100 to slowly move in the direction approaching the second member 200, or the buffer assembly is used to enable the first member 100 to maintain the tendency to move in the direction approaching the second member 200, or the buffer assembly is used to apply a pulling force to the first member 100 to approach the second member 200. So that after the ejector 3 returns to the collapsed state, the first member 100 can automatically continue to collapse and reset relative to the second member 200 in a buffered manner through the buffer assembly, to facilitate the use of the furniture member by the user, while being more silent and having a better experience. On the basis of the rebounding device 10, the buffer assembly is added, so that the furniture member with the rebounding and buffering functions is completed with a simple structure, and the problem is solved at a low cost.
[0108] In some specific embodiments, for example, taking the first component 100 as a drawer, with the pressing component 1 and the pop-out component 3 installed on the drawer, and the second component 200 as a cabinet, the buffer assembly can be a buffer slide rail that allows the drawer to be installed on the cabinet. The elastic force of the pop-out component 3 gradually switching from the closed state to the pop-out state is set to be greater than the pulling force of the buffer slide rail that makes the drawer tend to close. The stroke of the buffer is set to be greater than or equal to the drawer stroke between the first mating device 13 and the second mating device 31 being misaligned and separated until the drawer is completely closed. When an external force drives the first component 100, such as a drawer, to move towards the second component 200, such as a cabinet back panel, it can also drive the pop-out component 3 to move and abut against the cabinet back panel. This allows the pop-out component 3 to overcome the pull of the buffer and gradually switch from the closed state to the pop-out state after abutting against the cabinet back panel. Furthermore, during the process of the pop-out component 3 switching from the closed state to the pop-out state, it is set to have sufficient elasticity to push the drawer to move continuously away from the cabinet back panel until it exceeds the travel of the buffer and the drawer is fully or nearly fully opened. At the same time, during this process, when the drawer moves to a distance where the cabinet back panel and the pop-out component 3 are separated, the pressing component 1 rotates under the action of the first elastic component 2 to the point where the first mating device 13 and the second mating device 31 overlap. Through the movable extension or displacement of the third connecting part 311 on the first mating device 13 and / or the second mating device 31, the first mating device 13 can move past the second mating device 31 to the space between the cabinet back panel and the second mating device 31.
[0109] In the preferred case, the stroke of the ejector 3 from the retracted state to the ejecting state can be set to be greater than the stroke of the buffer. In the non-preferred case, when the stroke of the ejector 3 from the retracted state to the ejecting state is set to be less than or equal to the stroke of the buffer, in the case of abnormal use, after the ejector 3 abuts against the back plate of the cabinet, the user may not stop applying external force after the ejector 3 abuts against the back plate of the cabinet, but continue to apply external force to the drawer during the process of the ejector 3 from the retracted state to the ejecting state, so that when the drawer stops, the drawer can make the ejector 3 abut against the back plate of the cabinet under the pulling force of the buffer assembly, and at this time, the second matching device 31 is still located between the first matching device 13 and the back plate of the cabinet. In this case, the user can manually pull open the drawer to enable the first matching device 13 to move between the back plate of the cabinet and the second matching device 31, or the user can press the closed drawer to make the back plate of the cabinet directly abut against the ejector 3, so that the ejector 3 can switch from the ejecting state to the retracted state. This design has high fault tolerance and does not cause additional damage to the device in the case of abnormal use. Then, in the preferred case, when the external force pushes the drawer from the open state to the closed state, i.e., the external force drives the drawer to move towards the back plate of the cabinet, the pressing piece 1 rotates to the position where the first matching device 13 and the second matching device 31 are in contact under the action of the back plate of the cabinet through the third connecting part 311, and the stroke from the position to the fully closed state of the drawer is set to be greater than or equal to the stroke of the buffer. In the non-preferred case, when the stroke from the position where the first matching device 13 and the second matching device 31 are in contact to the fully closed state of the drawer is set to be less than the stroke of the buffer, so that when the drawer is within the stroke of the buffer, the buffer can pull the drawer to the position where the first matching device 13 and the second matching device 31 are in contact towards the back plate of the cabinet. In either case, in the case of normal use, a large enough external force can be set to push the drawer to move towards the closed state, i.e., a large enough external force can be set to drive the drawer to move towards the back plate of the cabinet, so that the pressing piece 1 can drive the ejector 3 to switch from the ejecting state to the retracted state. In the abnormal case, i.e., the external force is not large enough to enable the pressing piece 1 to drive the ejector 3 to switch from the ejecting state to the retracted state, the elastic force of the ejector 3 acts on the first matching device 13 through the second matching device 31, so that the rebounding force of the ejector 3 acts on the back plate of the cabinet through the third connecting part 311, thereby making the drawer move towards the open state. In this case, the user only needs to apply a large enough external force to the drawer to close it.
[0110] In addition, in a preferred case, the stroke of the buffer is greater than or equal to the stroke of the drawer from the misaligned separation of the first and second engagement devices 13 and 31 to the complete closing of the drawer. In a non-preferred case, the stroke of the buffer can also be less than the stroke from the misaligned separation of the first and second engagement devices 13 and 31 to the complete closing of the drawer, which will not be described herein.
[0111] In addition, in a non-normal use case, when the drawer is in the closed state, if the user directly pulls the drawer open, after using the drawer, the user can directly close the drawer, i.e., in this case, the rebound function is not used, only the buffering function is used, and thus the non-normal use case does not damage the furniture and the rebound device 10, and the design has a high fault tolerance.
[0112] For example, the first member 100 can be a cabinet body, the pressing member 1 and the ejecting member 3 are installed on the cabinet body, and the second member 200 can be a cabinet door, and the buffer assembly can be a buffer hinge for mounting the cabinet door on the cabinet body.
[0113] For example, the buffer assembly can be other forms of devices installed on the cabinet body and the drawer, or the buffer assembly can be other forms of devices installed on the cabinet body and the cabinet door, which will not be described herein.
[0114] In some embodiments, a second elastic member is included, and when the first engagement device 13 is in contact with the second engagement device 31 and drives the ejecting member 3 to switch from the ejecting state to the folding state, the second elastic member can drive the second member 200 to move towards the first member 100; at this time, the force of the second elastic member driving the second member 200 to move towards the first member 100 is greater than the reaction force of the first elastic member 2 and the resistance of the buffer assembly, so that the second member 200 slowly approaches the first member 100, achieving a buffering effect. The second elastic member is, for example, a spring or an elastic object. The buffering force generated by the buffer assembly is in the opposite direction of the force of the second elastic member, and when the second member 200 moves towards the first member 100 to a predetermined position, the resistance of the buffer assembly and the force of the first elastic member 2 are less than the force of the second elastic member, so that the second member 200 slowly approaches the first member 100, achieving a closing door or drawer.
[0115] In some embodiments, the pressing member 1 comprises a first swing arm 11 and a second swing arm 12 connected together, the second connecting portion 16 is located on the second swing arm 12, and the first matching device 13 is located on the second swing arm 12. The first connecting portion 15 can be located at the connection between the first swing arm 11 and the second swing arm 12, and the second connecting portion 16 is located at one end of the first swing arm 11. The first elastic member 2 can apply elastic force to both the first swing arm 11 and the second swing arm 12, so that the first swing arm 11 and the second swing arm 12 rotate in the same direction around the first connecting portion 15, and the second connecting portion 16 generates a pushing force on the second member 200 when the second connecting portion 16 contacts the second member 200. In practical applications, when the ejecting member 3 is switched from the retracted state to the ejecting state to drive the first member 100 to move away from the second member 200, the first elastic member 2 drives the second swing arm 12 to move, so that the first matching device 13 can pass over the second matching device 31. When an external force drives the first member 100 to move towards the second member 200, the second member 200 acts on the first swing arm 11 to drive the second swing arm 12 to move, and then the first matching device 13 on the second swing arm 12 contacts and links with the second matching device 31, so that the second swing arm 12 drives the ejecting member 3 to switch from the ejecting state to the retracted state, and the second member 200 can also continue to drive the second swing arm 12, so that the first matching device 13 can pass over the second matching device 31.
[0116] In some embodiments, the first swing arm 11 and the second swing arm 12 are fixedly connected, for example, the first swing arm 11 and the second swing arm 12 are integrally formed, or the first swing arm 11 and the second swing arm 12 are threadedly connected, or snap-connected, or concave-convex matched to form an integral structure, so that when the first swing arm 11 moves, the second swing arm 12 moves synchronously.
[0117] In some embodiments, the first swing arm 11 and the second swing arm 12 form a specific included angle, which can be in the range of 10° to 80°, for example, 10°, 20°, 40°, 60° or 80°, etc. The range of the included angle is designed according to the ejecting distance of the ejecting member 33 or the relative movement distance of the first member 100 and the second member 200.
[0118] The rebound device 10 is integrated, so that the rebound device 10 is more convenient to install on the first component 100 or the second component 200 and the structure is more firm and stable, in addition, the mounting plate 20 can be provided with multiple pieces to surround most of the rebound device 10, so as to play a protection effect on the rebound device 10.
[0119] In some embodiments, at least two adjusting grooves 201 are formed on the mounting plate 20, during installation, bolts or the like can be passed through the adjusting grooves 201 to lock the mounting plate 20 on the first component 100 or the second component 200, and by loosening the bolts, the bolts can slide along the adjusting grooves 201, so that the distance between the rebound device 10 and the first component 100 or the second component 200 can be adjusted, and the operation is convenient.
