Abstract
Description
A rebound device Technical Field
[0001] The present invention relates to the technical field of furniture hardware, and in particular to a rebound device used for pressing and rebounding to open and close and retract between a first component and a second component of furniture; in particular, it is used for pressing and rebounding to open and close and retract between a cabinet door and a cabinet body, and between a drawer and a cabinet body. Background Art
[0002] In the prior art, in order to make home decoration more simple and beautiful, and to maximize the use of space, furniture doors or drawers tend to use a handle-free push-rebound design. For example, the "A Rebounder" disclosed in Chinese patent application No. CN202223010206.1 has an ejection force equal to the force used in the folding process, which is inconvenient to use; moreover, it is easy to make mistakes during the folding process, resulting in rebound when the door is supposed to be folded.
[0003] For example, the Chinese patent application number CN202110567145.X discloses a “door closer with bidirectional buffering and resetting for door opening and closing”, the Chinese patent application number CN202210163435.2 discloses a “micro-motion cabinet door opener”, the Chinese patent application number CN202210870756.6 discloses a “door opening press rebounder”, and the Chinese patent application number CN202211164143.7 discloses a “cabinet door press rebound door opening device”. Although these types of rebounders solve the problem of cabinet door rebound, and use the lever principle to indirectly restore the rebounder to the folded state during the closing process of the cabinet door, their structure is too complicated, the manufacturing difficulty is high, and the production cost is high. Moreover, these designs are mainly aimed at the rebound opening and closing between the cabinet door and the cabinet body, and have poor applicability to the rebound opening and closing between the drawer and the cabinet body, and cannot meet people's needs. In addition, the cabinet door or drawer is relatively strenuous during the closing and folding process, and the user experience is poor. Summary of the Invention
[0004] In order to solve the technical problems in the prior art of complex rebound structures and the difficulty in closing and retracting cabinet doors or drawers, the present invention provides a rebound device, comprising:
[0005] a pop-up member, the pop-up member including a retracted state and a pop-up state, wherein when the first member moves in a direction approaching the second member so that the second member acts on the pop-up member, the pop-up member can switch from the retracted state to the pop-up state, and at the same time, the pop-up member can react on the first member and drive the first member to move in a direction away from the second member;
[0006] A pressing member, the pressing member includes a first matching device, and the ejecting member includes a second matching device;
[0007] The pressing member further includes a first connecting portion and a second connecting portion, wherein the first connecting portion is used to rotatably connect the pressing member to the first member, and the second connecting portion is capable of contacting the second member, and a straight-line distance from the first matching device to the first connecting portion is smaller than a straight-line distance from the second connecting portion to the first connecting portion;
[0008] a first elastic member, the first elastic member being used to apply an elastic force to the pressing member so as to cause the pressing member to rotate about the first connecting portion and to cause the second connecting portion to generate a thrust on the second member when in contact with the second member; the first cooperating device including a third connecting portion capable of movable extension, contraction or displacement, and / or the second cooperating device including a third connecting portion capable of movable extension, contraction or displacement;
[0009] When the pop-up member switches from the retracted state to the pop-up state to drive the first member to move in a direction away from the second member, the first elastic member drives the pressing member to rotate, so that at least a portion of the first mating device and / or at least a portion of the second mating device can drive the third connecting portion to move, expand, contract or displace, and the first mating device can move beyond the second mating device to between the second member and the second mating device;
[0010] Then, when an external force drives the first member to move in a direction approaching the second member, at least a portion of the first mating device and / or at least a portion of the second mating device can be mated and contacted with the third connecting portion, so that the pressure member drives the pop-up member to switch from the pop-up state to the retracted state;
[0011] Then, when the second member drives the pressing piece to continue to move, the first matching device can go over the second matching device, so that the second matching device is located between the second member and the first matching device.
[0012] Based on the above technical solution, the rebound device of the present invention is applied to the opening and closing of cabinet doors or drawers 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 an example, when the drawer is closed, the pop-up member is in a folded state. After the external force presses or pushes the drawer panel, the pop-up member switches from the folded state to the pop-up state. The pop-up member can act on the back panel or other parts of the cabinet body and then react to the drawer and drive the drawer to move away from the back panel of the cabinet body. At this time, the first elastic member drives the pressure member to rotate, and the second connecting part moves relative to the drawer toward the position of the cabinet back panel; through the movable extension or displacement setting of the third connecting part, the first matching device can cross the second matching device and move to between the cabinet back panel and the second matching device. The conception is ingenious and solves the problem at low cost with a simple structure.
[0013] Then, when the drawer is closed, an external force pushes the drawer toward the back panel of the cabinet, and the back panel or other parts of the cabinet can abut the second connection part to rotate the pressure piece and enable at least a part of the first mating device and / or at least a part of the second mating device to be mated and contacted with the third connection part, so that the pressure piece drives the pop-up piece to switch from the pop-up state to the retracted state. Since the straight-line distance from the first mating device to the first connection part is smaller than the straight-line distance from the second connection part to the first connection part, according to the lever principle, the external force used to drive the pop-up piece from the pop-up state to the retracted state is smaller than the elastic force of the pop-up piece from the retracted state to the pop-up state, making the drawer more labor-saving and smoother during the closing process, thereby improving the user experience.
[0014] Then, when the second member drives the pressure piece to continue moving, the first mating device can pass over the second mating device, thereby separating the first and second mating devices. That is, at least a portion of the first mating device and / or at least a portion of the second mating device can no longer be mated and connected with the third connecting portion, so that the second mating device is located between the second member and the first mating device. This is an ingenious design that solves the problem at a low cost with a simple structure.
[0015] Furthermore, by enabling at least a portion of the engaging means and / or at least a portion of the second engaging means to engage and contact the third connecting portion, the cabinet door or drawer can avoid direct contact with the pop-up member when the pop-up member is driven to transition from the pop-up state to the retracted state during closing, thereby reducing the risk of damage to the pop-up member and increasing the lifespan of the pop-up member. The rebound device of the present invention has a simple structure, is easy to produce, and has a low manufacturing cost.
[0016] In some embodiments, the first cooperating means comprises an escape space formed on the pressing member, and / or the second cooperating means comprises an escape space formed on the ejecting member;
[0017] When external force drives the first component to move in the direction approaching the second component, at least a part of the first cooperating device and / or the second cooperating device can abut against the third connecting portion to drive the pop-up member to switch from the pop-up state to the retracted state; then when the second component drives the pressing member to continue moving, the third connecting portion can enter the avoidance space so that the first cooperating device can pass over the second cooperating device, so that the second cooperating device is located between the second component and the first cooperating device.
[0018] When the first member moves toward the direction approaching the second member, the pressure piece rotates along with the movement of the first member, and a portion of the pressure rod can push the third connection portion to switch the pop-up member from the pop-up state to the retracted state. By opening the avoidance space, after the pop-up member switches to the retracted state, the third connection portion can pass through the avoidance space, so that the pressure piece successfully passes over the third connection portion, 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 switch the pop-up member from the retracted state to the pop-up state, the second matching position is located between the first matching position and the second member, so that when the pop-up member is ejected, the movement of the pop-up member is not affected by the pressure rod, making the movement of the first member smoother. The rotation of the pressure piece relative to the first member and / or the pop-up member is used to enable the first matching device and the second matching device to be dislocated and separated when the pressure piece rotates to a specific position. The design is ingenious and solves the problem at a low cost with a simple structure.
[0019] It should be noted that the setting of the avoidance space is only one way in which the first mating device and the second mating device can be dislocated and separated. This patent is not limited to this method. For example, other components can also be set to clamp the first mating device and / or the second mating device so that the first mating device can be dislocated and separated from the second mating device at a specific position.
[0020] In some embodiments, at least one side surface of the avoidance space is a curved surface or an inclined surface, so as to make the separation of the first matching device and the second matching device smoother.
[0021] In some embodiments, the third connecting portion is connected to a third elastic member; the third connecting portion is formed with a first surface, and the first surface is an inclined surface or an arc surface;
[0022] When the second mating device is located between the second member and the first mating device and the first member moves in a direction away from the second member, at least a portion of the first mating device can act on the first surface of the second mating device and cause the third elastic member of the second mating device to deform so that the first mating device can pass over the third connecting portion of the second mating device and cause the first mating device to be located between the second member and the second mating device. After the first mating device passes over the first surface, the third elastic member can drive the third connecting portion of the second mating device to return to its original state; and / or
[0023] When the second mating device is located between the second member and the first mating device and the first member moves away from the second member, at least a portion of the second mating device can act on the first surface of the first mating device and cause the third elastic member of the first mating device to deform so that the second mating device can pass over the third connecting portion of the first mating device, and the first mating device is located between the second member and the second mating device. After the second mating device passes over the first surface, the third elastic member can drive the third connecting portion of the second mating device to return to its original state. The provision of the inclined or curved surface converts the horizontal thrust into vertical pressure; the provision of the pressure member 1 facilitates the resetting of the ejection member 3. The design is ingenious and solves the problem at a low cost with a simple structure.
[0024] In some embodiments, the first elastic member includes a torsion spring, and at least a portion of the pressure member passes through the torsion spring and is rotatably connected to the first component. The torsion spring can apply elastic force to the pressure member so that the pressure member generates a thrust on the second component when the pressure member contacts the second component; and / or, the torsion spring can apply elastic force to the pressure member so that at least a portion of the first mating device and / or at least a portion of the second mating device can drive the third connecting part to move, expand, contract or displace, so that the first mating device can move across the second mating device to between the second component and the second mating device.
[0025] In some embodiments, at least one limiting portion is further included, and the limiting portion is used to limit the rotation range of the pressing member relative to the first member. In at least one embodiment, when the first matching device can move beyond the second matching device to the first time between the second member and the second matching device, the pressing member stops rotating, so that the first matching device and / or the second matching device can be in a matching contact connection state or a state close to a matching contact connection state with the third connecting portion; when the second member moves toward the pressing member from a distance relative to the pressing member and collides with the pressing member, because the first matching device and / or the second matching device can be in a matching contact connection state or a state close to a matching contact connection state with the third connecting portion, the damage to the first matching device and / or the second matching device and the third connecting portion can be minimized, thereby increasing the service life and providing a better user experience.
[0026] In some embodiments, a reciprocating mechanism is further included, and the reciprocating mechanism is used to smoothly switch the pop-up member between the folded state and the pop-up state.
[0027] In some embodiments, a buffer assembly is included. When the first mating device moves toward the second mating device, away from the second member, and past the second mating device, the buffer assembly is used to slowly move the first member toward the second member. This allows the pop-up member to return to its retracted state, allowing the first member to continue to retract and reset relative to the second member in a buffered manner, facilitating user experience while reducing noise and providing a superior user experience. Adding a buffer assembly to the rebound mechanism allows for a simple, yet cost-effective, furniture component with both rebound and buffering functions.
[0028] In some embodiments, a second elastic member is included. When the first mating device contacts and engages with the first mating device and drives the pop-up member to switch from the pop-up state to the retracted state, the second elastic member can drive the second member to move in a direction close to the first member; at this time, the force of the second elastic member driving the second member to move in a direction close to the first member is greater than the reaction force of the first elastic member and the resistance of the buffer component to it.
[0029] In some embodiments, a mounting plate is further included, the mounting plate being fixed to the first component or the second component, a portion of the pressing member being pivotally connected to the mounting plate; and / or the ejecting member being located on the mounting plate; and / or the first elastic member being located on the mounting plate; and / or at least a portion of the buffer assembly being located on the mounting plate. This facilitates mounting the rebound device on the component and makes the structure more secure and stable. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] In the prior art, there are technical problems as described in the background art.
[0064] In order to solve the above technical problems, please refer to Figures 1 to 26. An embodiment of the present invention provides a rebound device 10, which includes a pop-up member 3, a pressure member 1, and a first elastic member 2. The pop-up member 3 includes a folded state and a pop-up state. When the first component 100 moves in a direction close to the second component 200 so that the second component 200 acts on the pop-up member 3, the pop-up member 3 can switch from the folded state to the pop-up state. At the same time, the pop-up member 3 can react on the first component 100 and can drive the first component 100 to move in a direction away from the second component 200; the pressure member 1 includes a first matching device 13 , the pop-up member 3 includes a second matching device 31; the pressing member 1 also includes a first connecting portion 15 and a second connecting portion 16, the first connecting portion 15 is used to make the pressing member 1 rotatably connected to the first component 100, and the second connecting portion 16 can contact the second component 200, and the straight-line distance from the first matching device 13 to the first connecting portion 15 is smaller than the straight-line distance from the second connecting portion 16 to the first connecting portion 15; the first elastic member 2 is used to apply elastic force to the pressing member 1, so that the pressing member 1 rotates around the first connecting portion 15, and the second connecting portion 16 generates a thrust on the second component 200 when it contacts the second component 200; the first The first engaging device 13 includes a third connecting portion 311 that can be flexibly extended, retracted or displaced, and / or the second engaging device 31 includes a third connecting portion 311 that can be flexibly extended, retracted or displaced; wherein, when the pop-up member 3 switches from the folded state to the pop-up state to drive the first component 100 to move in a direction away from the second component 200, the first elastic member 2 drives the pressing member 1 to rotate, so that at least a portion of the first engaging device 13 and / or at least a portion of the second engaging device 31 can drive the third connecting portion 311 to flexibly extend, retract or displace, and the first engaging device 13 can move over the second engaging device 31. Move to between the second component 200 and the second matching device 31; then, when the external force drives the first component 100 to move in the direction close to the second component 200, at least a part of the first matching device 13 and / or at least a part of the second matching device 31 can be matched and contacted with the third connecting portion 311, so that the pressure piece 1 drives the pop-up piece 3 to switch from the pop-up state to the retracted state; then, when the second component 200 drives the pressure piece 1 to continue to move, the first matching device 13 can pass over the second matching device 31, so that the second matching device 31 is located between the second component 200 and the first matching device 13.
[0065] The rebound device 10 of the present invention is used for opening and closing furniture such as cabinet doors or drawers. The present invention is not limited to the specific structures of the first component 100 and the second component 200. For example, when the first component 100 is a cabinet body and the second component 200 is a cabinet door; or when the first component 100 is a drawer and the second component 200 is a cabinet body; or vice versa, when the first component 100 is a cabinet door and the second component 200 is a cabinet body. The movement of the first component 100 and the second component 200 is relative, that is, when an external force drives the first component 100 to move toward the second component 200, it can also be understood that the external force drives the second component 200 to move toward the first component 100. When the first component 100 or the second component 200 is fixed, when an external force acts on one of the first component 100 and the second component 200, the external force can react to the other of the first component 100 or the second component 200. For example, when the second component 200 is fixed, when an external force acts on the second component 200, the force acting on the second component 200 can react to the first component 100, so that the first component 100 and the second component 200 are relatively separated.
[0066] For example, the first component 100 of this embodiment can be a drawer, and the second component 200 can be the back panel or other part of the cabinet; for example, the first connecting part 15 can rotatably install the pressure piece 1 on the drawer, and the pop-up piece 3 is also installed on the drawer, and the second connecting part 16 of the pressure piece 1 is connected or abutted or nearly abutted to the back panel of the cabinet. When the pop-up piece 3 is in the folded state, the external force drives the drawer to move toward the direction close to the back panel of the cabinet. After the pop-up piece 3 abuts against the back panel of the cabinet, the pop-up piece 3 is driven to switch from the folded state to the pop-up state. The pop-up piece 3 generates a thrust on the back panel of the cabinet. Since the back panel of the cabinet is fixed, the thrust reacts on the drawer and separates the drawer from the back panel of the cabinet, so that the drawer is in a relatively open state.
[0067] For another example, the first component 100 of this embodiment may be a cabinet body, and the second component 200 may be a cabinet door; for example, the first connecting portion 15 rotatably mounts the pressure piece 1 on the cabinet body, and the pop-up piece 3 is also mounted on the cabinet body. The second connecting portion 16 of the pressure piece 1 is connected to or abuts against the cabinet door. When the pop-up piece 3 is in a retracted state, when an external force acts on the cabinet door, the cabinet door is driven to move toward the direction close to the cabinet body. After the pop-up piece 3 abuts against the cabinet door, the pop-up piece 3 is driven to switch from the retracted state to the pop-up state. The pop-up piece 3 generates a thrust on the cabinet door, pushing the cabinet door and the cabinet body to be relatively separated, so that the cabinet door is in a relatively open state.
[0068] Among them, when the pop-up member 3 is in the folded state, the first situation is the state of normal use: when the first component 100 and the second component 200 are close together (the state of closing the door or closing the drawer), the second component 200 and the pop-up member 3 can be in direct contact or close contact, for example, there is a gap between the second component 200 and the end of the pop-up member 3; the second situation is the state of abnormal use, that is, the first component 100 and the second component 200 can be in a state of being away from each other (the state of opening the door or opening the drawer); no matter which situation, as long as the external force drives the first component 100 to move in the direction of approaching the second component 200, and can drive the pop-up member 3 to abut against the second component 200, so that after the pop-up member 3 abuts against the second component 200, the pop-up member 3 gradually switches from the folded state to the pop-up state, the pop-up member 3 can push the second component 200 to move (or the reaction pushes the first component 100 to move), so that the first component 100 and the second component 200 are relatively separated, so that the furniture is in the open state.
[0069] The first connection portion 15 may be, for example, a rotating shaft, a sphere, or other rotating structure, and a portion of the pressing member 1 is rotatably mounted on the first member 100 via the first connection portion 15. The pressing member 1 may be directly rotatable with the first member 100 via the first connection portion 15. Alternatively, the pressing member 1 may be rotatably connected to the box body, housing, or mounting plate 20 before the box body, housing, or mounting plate 20 is fixed to the first member 100, thereby indirectly rotatable with the first member 100.
[0070] The second connection portion 16 may be, for example, an end portion of the pressing piece 1 , a part of the pressing piece 1 , or a component installed on the pressing piece 1 .
[0071] The embodiment of the present invention does not limit the shape or structure of the third connection part 311, and the embodiment of the present invention does not limit the movable expansion or displacement direction of the third connection part 311. For example, the third connection part 311 can be a block or a column. For example, the third connection part 311 can be movable expansion or displacement in the up and down directions, left and right directions, or front and back directions relative to the pressure piece 1, and / or the third connection part 311 can be movable expansion or displacement in the up and down directions, left and right directions, or front and back directions relative to the pop-up piece 3.
[0072] The linear distance from the first engaging device 13 to the first connecting portion 15 may refer to the linear distance from the portion of the first engaging device 13 that is in contact with the second engaging device 31 when the first engaging device 13 and the second engaging device 31 engage and engage to drive the pop-up member 3 to switch from the pop-up state to the retracted state, and this distance is less than the linear distance from the second connecting portion 16 to the first connecting portion 15. When an external force pushes the first member 100 toward the second member 200, the second member 200 drives the pressing member 1 to rotate about the first connecting portion 15 via the second connecting portion 16. Since the linear distance from the second connecting portion 16 to the first connecting portion 15 is greater than the distance from the first engaging device 13 to the first connecting portion 15, according to the principle of leverage, the external force acting on the first member 100 to switch the pop-up member 3 from the pop-up state to the retracted state is less than the force exerted by the pop-up member 3 on the first member 100 when switching from the retracted state to the pop-up state. This makes the process of the external force pushing the first member 100 toward the second member 200 more labor-saving and smoother, thereby improving the user experience.
[0073] In some embodiments, the second connecting portion 16 and the cabinet back panel are in contact with each other. When an external force drives the first component 100, such as a drawer, to move toward the second component 200, such as the cabinet back panel, it can drive the pop-up member 3 to move and abut against the cabinet back panel, so that after the pop-up member 3 abuts against the cabinet back panel, the pop-up member 3 gradually switches from a folded state to a pop-up state; at this moment when the pop-up member 3 abuts against the cabinet back panel, the second matching device 31 is located between the first matching device 13 and the cabinet back panel.
[0074] As the pop-up member 3 gradually switches from the folded state to the pop-up state, sufficient elastic force can be set to push the drawer to continue moving in the direction away from the cabinet back panel until the drawer is fully opened or nearly fully opened. During this process, it can be set that when the drawer moves to a distance away from the cabinet back panel and the pop-up member 3, the pressure member 1 rotates to the overlap position of the first matching device 13 and the second matching device 31 under the action of the first elastic member 2, and the first matching device 13 can move over the second matching device 31 to between the cabinet back panel and the second matching device 31 by the movable extension or displacement setting of the third connecting portion 311 on the first matching device 13 and / or the second matching device 31. During this process, the second connecting portion 16 can be kept in close contact with the cabinet back panel under the action of the first elastic member 2. In the case of abnormal use, when the pop-up member 3 abuts against the cabinet back panel during the process of switching from the folded state to the pop-up state, the external force applied by the user may not stop after the pop-up member 3 abuts against the cabinet back panel, but may continue to apply external force to the drawer for a period of time during the process of switching from the folded state to the pop-up state after the pop-up member 3 abuts against the cabinet back panel, so that when the drawer stops, the second matching device 31 is still located between the first matching device 13 and the cabinet back panel. In this case, the user can manually open the drawer so that the first matching device 13 can move over the second matching device 31 to between the cabinet back panel and the second matching device 31, or the user can press the drawer to close so that the cabinet back panel directly abuts against the pop-up member 3, so that the pop-up member 3 switches from the pop-up state to the folded state. This design has a high fault tolerance rate and will not cause additional damage to the device in the case of abnormal use.
[0075] Under normal use, then, when external force pushes the drawer from the open state to the closed state, that is, when the external force drives the drawer to move in the direction close to the cabinet back panel, the pressure piece 1 rotates to the point where the first matching device 13 and the second matching device 31 are matched and contacted under the action of the cabinet back panel through the third connection part 311. At this time, the first matching device 13 and the third connection part 311 located on the second matching device 31 can be matched and contacted, or the second matching device 31 can be matched and contacted with the third connection part 311 located on the first matching device 13, or the third connection part 311 on the first matching device 13 can be matched and contacted with the third connection part 311 located on the second matching device 31. The external force is set to be large enough so that the pressure piece 1 can drive the pop-up piece 3 to switch from the pop-up state to the retracted state. In an abnormal situation, that is, when the external force is not large enough to prevent the pressure member 1 from driving the pop-up member 3 to switch from the pop-up state to the retracted state, the elastic force of the pop-up member 3 acts on the first matching device 13 through the second matching device 31, so that the pop-up member 3 rebounds on the cabinet back panel through the second connecting portion 16, thereby moving the drawer to the open state. In this case, the user only needs to apply a sufficiently large external force to the drawer. Then, it is set that the cabinet back panel continues to drive the pressure member 1 to continue to move, and the first matching device 13 can pass over 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 portion 311, so that the second matching device 31 is located between the second component 200 and the first matching device 13, and the drawer can be driven to the closed state.
[0076] In addition, in the case of abnormal use, when the drawer is in a closed state, if the user directly pulls the drawer open, then after using the drawer, the user can directly close the drawer. That is, in this case, the function of the rebound device 10 is equivalent to not being used. Therefore, this abnormal use does not cause damage to the furniture and the rebound device 10, and the design has a high fault tolerance rate.
[0077] Furthermore, by enabling at least a portion of the first engaging means 13 and / or at least a portion of the second engaging means 31 to engage and connect with the third connecting portion 311, the cabinet back panel does not directly contact the pop-up member 3 when the drawer is closed, driving the pop-up member 3 to transition from the pop-up state to the retracted state. This reduces the risk of damage to the pop-up member 3 and increases the lifespan of the pop-up member 3. The rebound device 10 of the present invention has a simple structure, is easy to produce, and has a low manufacturing cost.
[0078] In some embodiments, the first mating device 13 includes an escape space 131 formed on the pressure member 1, and / or the second mating device 31 includes an escape space 131 formed on the pop-up member 3. When an external force drives the first member 100 toward the second member 200, at least a portion of the first mating device 13 and / or the second mating device 31 can abut against the third connection portion 311, thereby driving the pop-up member 3 to switch from the popped-out state to the retracted state. Then, when the second member 200 drives the pressure member 1 to continue moving, the third connection portion 311 can enter the escape space 131, allowing the first mating device 13 to pass over the second mating device 31, so that the second mating device 31 is located between the second member 200 and the first mating device 13. The escape space 131 can be a groove, a notch, or a slot structure. Among them, the avoidance space 131 and the third connection part 311 are relative. For example, the first matching device 13 may include the avoidance space 131, and the second matching device 31 may include the third connection part 311; for another example, the second matching device 31 may include the avoidance space 131, and the first matching device 13 may include the third connection part 311; for another example, the first matching device 13 and the second matching device 31 each have a third connection part 311. When the pressure piece 1 is rotated to a specific position, the third connection parts 311 of the first matching device 13 and the second matching device 31 can be staggered with each other to form the avoidance space 131 with each other. Now let's take an example: for example, the second matching device 31 includes a third connecting portion 311 that can be flexibly extended, retracted or displaced, and the first matching device 13 includes an avoidance space 131 formed on the pressure piece 1; when an external force drives the first component 100, such as a drawer, to move toward the direction approaching the second component 200, such as the back panel of the cabinet, at least a portion of the first matching device 13 can abut against the third connecting portion 311 to drive the pop-up member 3 to switch from the pop-up state to the retracted state; then when the back panel of the cabinet drives the pressure piece 1 to continue to move, the third connecting portion 311 can enter the avoidance space 131, so that the first matching device 13 can pass over the second matching device 31, so that the second matching device 31 is located between the second component 200 and the first matching device 13.22-25 , when the first component 100, such as a drawer, moves toward the direction approaching the second component 200, such as the back panel of a cabinet, the pressure piece 1 will rotate with the movement of the first component 100, and a part of the pressure piece 1 can push the third connection part 311 to switch the pop-up member 3 from the pop-up state to the retracted state. By opening the avoidance space 131, after the pop-up member 3 switches from the pop-up state to the folded state, the third connection part 311 can pass through the avoidance space 131, so that the pressure piece 1 successfully crosses the third connection part 311, so that the second matching device 31 is located between the second component 200 and the first matching device 13; then, when the drawer is pressed to switch the pop-up member 3 from the folded state to the pop-up state, the second matching position is located between the first matching position and the back panel of the cabinet, so that when the pop-up member 3 pops out, the movement of the pop-up member 3 is not affected by the pressure rod, so that the movement of the drawer is smoother. By utilizing the rotation of the pressure member 1 relative to the drawer and / or ejector 3, the first engaging means 13 and the second engaging means 31 can be dislocated and separated when the pressure member 1 is rotated to a specific position. This ingenious design solves the problem with a simple structure and low cost. The principles of the remaining two scenarios are the same as those of the above solution and will not be elaborated here.
[0079] In some embodiments, at least one side of the escape space 131 is a curved or inclined surface to facilitate smoother separation of the first mating device 13 and the second mating device 31. In particular, when the side of the escape space 131 is a curved surface, stress concentration can be avoided, reducing the risk of wear of the pressing element 1 and extending the service life of the pressing element 1.
[0080] It should be noted that the setting of the avoidance space 131 is only one way in which the first mating device 13 and the second mating device 31 can be dislocated and separated. This patent is not limited to this method. For example, other components can also be set to engage with the first mating device 13 and / or the second mating device 31 when the pressure piece 1 rotates to a specific position, so that the first mating device 13 and the second mating device 31 can be dislocated and separated at a specific position. For example, the pop-up member 3 also includes a driving portion that drives the third connection portion 311 to move, retract or displace. The driving portion is, for example, a buckle or a hook. When an external force drives the first component 100 to move in a direction close to the second component 200, at least a portion of the first mating device 13 can be against the third connection portion 311 to drive the pop-up member 3 to switch from the pop-up state to the retracted state. At least a portion of the first mating device 13 acts on the driving portion to cause the driving portion to drive the third connection portion 311 to retract or displace, so that the first mating device 13 can cross the third connection portion 311, that is, the pressure piece 1 successfully crosses the third connection portion 311, so that the second mating device 31 is located between the second component 200 and the first mating device 13. For another example, the ejection member 3 further includes a driving portion capable of driving the first mating device 13 and / or the second mating device 31 at a specific position. The driving portion is, for example, an undercut or hook portion. When an external force drives the first component 100 to move in a direction approaching the second component 200, at least a portion of the first mating device 13 can abut against the second mating device 31 to drive the ejection member 3 to switch from the ejected state to the retracted state. After that, the driving portion can act on the first mating device 13 and / or the second mating device 31 to cause the first mating device 13 and the second mating device 31 to be dislocated and separated, so that the first mating device 13 can pass over the second mating device 31, so that the second mating device 31 is located between the second component 200 and the first mating device 13. The mating principles of other cases are similar to those of the above-mentioned scheme. As long as the first mating device 13 and the second mating device 31 can be dislocated and separated at a specific position, they will not be described in detail here.
[0081] In some embodiments, the third connecting portion 311 is connected to the third elastic member 312; the third connecting portion 311 is formed with a first surface 313, and the first surface 313 can be an inclined surface or an arc surface; wherein, when the second mating device 31 is located between the second component 200 and the first mating device 13 and the first component 100 moves in a direction away from the second component 200, at least a portion of the first mating device 13 can act on the first surface 313 of the second mating device 31 and cause the third elastic member 312 of the second mating device 31 to deform so that the first mating device 13 can pass over the third connecting portion 311 located in the second mating device 31 and cause the first mating device 13 to be located between the second component 200 and the second mating device 31. After the first mating device 13 passes over the first surface 313, the third elastic member 312 can drive the third connecting portion 311 located in the second mating device 31 to return to its original state. As shown in Figure 25, when the first component 100 is pressed to switch the pop-up member 3 from the folded state to the pop-up state, the second mating position is located between the first mating position and the second component 200. Therefore, when the pop-up member 3 is popped out, the movement of the pop-up member 3 is not affected by the pressure member 1. The first mating device 13 will move to contact the first surface 313 under the drive of the first elastic member 2. Since the first surface 313 is an inclined surface or an arc surface, the first elastic member 2 is set to apply sufficient elastic force to the pressure member 1 so that the lateral thrust applied by the first mating device 13 to the third connection part 311 can be converted into vertical pressure. Therefore, the first mating device 13 can gradually press down the third connection part 311 during the movement until the first mating device 13 completely crosses the third connection part 311, and then the third elastic member 312 will push the third connection part 311 upward to ensure that when the first component 100 moves in the direction close to the second component 200, the first mating device 13 can contact and cooperate with the second mating device 31 to drive the pop-up member 3 to switch from the pop-up state to the folded state. This embodiment utilizes the cooperation between the third elastic member 312 and the inclined surface or the arc surface to make the movement and extension of the third connecting portion 311 smoother, so that when the first component 100 moves in the direction away from the second component 200, the first cooperating device 13 can smoothly pass over the second cooperating device 31, so that when the first component 100 moves in the direction away from the second component 200, the first component 100 will not get stuck, and the structure is simple and the manufacturing cost is low.
[0082] In some embodiments, when the second mating device 31 is located between the second member 200 and the first mating device 13 and the first member 100 moves in a direction away from the second member 200, at least a portion of the second mating device 31 can act on the first surface 313 of the first mating device 13 and cause the third elastic member 312 of the first mating device 13 to deform, allowing the second mating device 31 to pass over the third connecting portion 311 located in the first mating device 13 and position the first mating device 13 between the second member 200 and the second mating device 31. After the second mating device 31 passes over the first surface 313, the third elastic member 312 can drive the third connecting portion 311 located in the second mating device 31 to return to its original state. Alternatively, there is a situation where the first mating device 13 has a first surface 313 and the second mating device 31 also has a first surface 313. The operating principle of this situation refers to the combination of the above two embodiments and is not further described here.
[0083] In some embodiments, the first elastic member 2 includes a torsion spring, and at least a portion of the pressure member 1 can be passed through the torsion spring and rotatably connected to the first component 100. The torsion spring can apply elastic force to the pressure member 1 so that the pressure member 1 generates a thrust on the second component 200 when the pressure member 1 contacts the second component 200; and / or, the torsion spring can apply elastic force to the pressure member 1 so that at least a portion of the first mating device 13 and / or at least a portion of the second mating device 31 can drive the third connecting portion 311 to move, expand, contract or displace, and the first mating device 13 can move across the second mating device 31 to between the second component 200 and the second mating device 31. A torsion spring can be connected to the first connecting portion 15. When the first member 100 and the second member 200 are relatively close, the torsion spring can exert an elastic force on the pressure piece 1, causing the first member 100 and the second member 200 to have a tendency to separate relative to each other, thereby maintaining the second connecting portion 16 in contact with the second member 200. The torsion spring is configured to have sufficient force to enable at least a portion of the first mating device 13 and / or at least a portion of the second mating device 31 to drive the third connecting portion 311 to move, expand, contract, or displace. In other embodiments, the first elastic member 2 can also be other elastic objects.
[0084] In some embodiments, the embodiments of the present invention further include at least one limiting portion 5, which is used to limit the rotation range of the pressure piece 1 relative to the first component 100. The limiting portion 5 is, for example, a protrusion or a bump structure. The limiting portion 5 may be on the first component 100 or the rebound device 10, or the limiting portion 5 may be an elastic limitation of the first elastic member 2, which is not limited here. The limiting portion 5 is used to limit the rotation range of the pressing piece 1 around the first connecting portion 15. For example, in at least one embodiment, the limiting portion 5 stops the pressing piece 1 from rotating just when the first mating device 13 has just crossed the second mating device 31 and moved to the first position between the second component 200 and the second mating device 31, so that the first mating device 13 and / or the second mating device 31 can be in a mating contact connection state or a state close to a mating contact connection state with the third connecting portion 311; when the second component 200 moves toward the pressing piece 1 from a distance relative to the pressing piece 1 and collides with the pressing piece 1, because the first mating device 13 and / or the second mating device 31 can be in a mating contact connection state or a state close to a mating contact connection state with the third connecting portion 311, the damage caused by the collision between the first mating device 13 and / or the second mating device 31 and the third connecting portion 311 can be minimized, thereby increasing the service life and providing a better user experience.
[0085] In some embodiments, the rebound device 10 of the present invention further includes a reciprocating mechanism 4, which is used to smoothly switch the pop-up member 3 between the retracted state and the pop-up state. When the pop-up member 3 is in the retracted state, the reciprocating mechanism 4 maintains the pop-up member 3 in the retracted state. The specific structure of the reciprocating mechanism 4 is similar to the rebound structure of the rebound slide rail and will not be described in detail here.
[0086] In some embodiments, a buffer assembly is included. When the first mating device 13 moves toward the second mating device 31, away from the second member 200, and past the second mating device 31, the buffer assembly is used to slowly move the first member 100 toward the second member 200. After the pop-up member 3 returns to its retracted state, the first member 100 automatically retracts and repositions relative to the second member 200 using the buffer assembly, facilitating user experience while reducing noise and providing a superior user experience. Adding the buffer assembly to the rebound device 10 allows for a simpler structure with both rebound and buffering functions, solving this problem at a low cost.
[0087] In some specific embodiments, for example, taking the first component 100 as a drawer, the pressure piece 1 and the pop-up piece 3 as an installation on the drawer, and the second component 200 as an embodiment of a cabinet, the buffer assembly can be a buffer slide rail that enables the drawer to be installed on the cabinet body, and the elastic force of the pop-up piece 3 gradually switching from the folded state to the pop-up state is set to be greater than the pulling force of the buffer of the buffer slide rail that causes the drawer to tend to the closed state, and the stroke of the buffer is set to be greater than or equal to the drawer stroke between the time when the first cooperating device 13 and the second cooperating device 31 are misaligned and separated and when the drawer is completely closed. When external force drives the first component 100, such as a drawer, to move in the direction approaching the second component 200, such as the cabinet back panel, and is able to drive the pop-up member 3 to move and abut against the cabinet back panel, so that after the pop-up member 3 abuts against the cabinet back panel, the pop-up member 3 can break through the pulling force of the buffer and gradually switch from the folded state to the pop-up state; and it is set that the pop-up member 3 can have sufficient elastic force to push the drawer to continue moving in the direction away from the cabinet back panel until it exceeds the stroke of the buffer so that the drawer is fully opened or nearly fully opened. At the same time, in this process, when the drawer moves to a distance where the cabinet back panel and the pop-up member 3 are separated, the pressure member 1 rotates to the point where the first matching device 13 and the second matching device 31 overlap under the action of the first elastic member 2. Through the movable extension or displacement setting of the third connecting part 311 on the first matching device 13 and / or the second matching device 31, the first matching device 13 can move beyond the second matching device 31 to between the cabinet back panel and the second matching device 31.
[0088] In a preferred embodiment, the stroke of the pop-up member 3 switching from the folded state to the pop-up state can be set to be greater than the stroke of the buffer. In a non-preferred embodiment, when the stroke of the pop-up member 3 switching from the folded state to the pop-up state is set to be less than or equal to the stroke of the buffer, in the case of abnormal use, after the pop-up member 3 abuts against the cabinet back panel, during the process of the pop-up member 3 switching from the folded state to the pop-up state, the user may not stop applying external force after the pop-up member 3 abuts against the cabinet back panel, but may apply external force to the drawer all the time or for a certain period of time during the process of the pop-up member 3 switching from the folded state to the pop-up state after the pop-up member 3 abuts against the cabinet back panel, so that when the drawer stops, the drawer can make the pop-up member 3 abut against the cabinet back panel 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 cabinet back panel. In this case, the user can manually open the drawer so that the first matching device 13 can move over the second matching device 31 to between the cabinet back panel and the second matching device 31, or the user can press to close the drawer so that the cabinet back panel directly abuts the pop-up member 3, so that the pop-up member 3 switches from the pop-up state to the retracted state. This design has a high fault tolerance rate and will not cause additional damage to the device under abnormal use. Then, in the preferred case, when an external force pushes the drawer from the open state to the closed state, that is, when the external force drives the drawer to move in the direction close to the cabinet back panel, the pressure piece 1 rotates to the contact connection point where the first matching device 13 and the second matching device 31 are matched under the action of the cabinet back panel through the third connecting portion 311 to the fully closed drawer. The stroke is set to be greater than or equal to the stroke of the buffer. In a non-preferred case, when the stroke from the mating contact connection of the first mating device 13 and the second mating device 31 to the complete closure of the drawer is set to be smaller than the stroke of the buffer, so that when the drawer is within the stroke of the buffer, the buffer can pull the drawer toward the cabinet back panel to the mating contact connection of the first mating device 13 and the second mating device 31. In either case, when in normal use, a sufficiently large external force can be set to push the drawer toward the closed state, that is, a sufficiently large external force can be set to drive the drawer toward the direction close to the cabinet back panel, so that the pressure piece 1 can drive the pop-up piece 3 to switch from the pop-up state to the retracted state. In an abnormal situation, that is, when the external force is not large enough to enable the pressure piece 1 to drive the pop-up piece 3 to switch from the pop-up state to the retracted state, the elastic force of the pop-up piece 3 acts on the first mating device 13 through the second mating device 31 so that the rebound force of the pop-up piece 3 acts on the cabinet back panel through the third connection part 311, so that the drawer moves toward the open state. In this case, the user only needs to apply a sufficiently large external force to the drawer to close it.
[0089] In addition, in a preferred embodiment, the stroke of the buffer is greater than or equal to the drawer stroke from the time when the first mating device 13 and the second mating device 31 are dislocated and separated to the time when the drawer is fully closed. In a less preferred embodiment, the stroke of the buffer may also be less than the stroke from the time when the first mating device 13 and the second mating device 31 are dislocated and separated to the time when the drawer is fully closed, which will not be further described here.
[0090] In addition, in the case of abnormal use, when the drawer is in a closed state, if the user directly pulls the drawer open, then after using the drawer, the user can directly close the drawer. That is, in this case, the rebound function is equivalent to not being used, and only the buffering function is used. Therefore, this abnormal use does not cause damage to the furniture and the rebound device 10, and the design has a high fault tolerance rate.
[0091] For another example, the first component 100 may be a cabinet body, the pressing member 1 and the pop-up member 3 may be mounted on the cabinet body, the second component 200 may be a cabinet door, and the buffer assembly may be a buffer hinge for mounting the cabinet door on the cabinet body.
[0092] For another example, the buffer assembly may be other forms of devices installed on the cabinet body and the drawer, or the buffer assembly may be other forms of devices installed on the cabinet body and the cabinet door, which will not be described in detail here.
[0093] In some embodiments, a second elastic member is included. When the first mating device 13 engages with the second mating device 31 and drives the pop-up member 3 to switch from the pop-up state to the retracted state, the second elastic member can drive the second member 200 to move in a direction close to the first member 100. At this time, the force of the second elastic member driving the second member 200 in the direction close to the first member 100 is greater than the reaction force of the first elastic member 2 and the resistance of the buffer assembly, thereby causing the second member 200 to slowly approach the first member 100, achieving a buffering effect. The second elastic member is, for example, a spring or an elastic object. The direction of the buffering force generated by the buffer assembly is opposite to the direction of the force of the second elastic member. When the second member 200 moves in the direction close to the first member 100 to a preset position, the resistance generated by the buffer assembly and the force of the first elastic member 2 are less than the force of the second elastic member, thereby causing the second member 200 to slowly approach the first member 100, thereby closing the door or drawer.
[0094] The rebound device of the embodiment of the present invention further includes a mounting plate 20, which is fixed to the first member 100 or the second member 200.
