Description

Technical Field

[0001] The present invention relates to the technical field of furniture hardware, and particularly to a rebound device, which is applied to the pressing, rebounding, popping open, closing, and retracting between a first component and a second component of furniture; particularly applied to the pressing, rebounding, popping open, closing, and retracting 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 concise, beautiful, and maximize the use of space, furniture doors or drawers tend to use a touchless pressing and rebounding design. For example, in the "A Rebounder" disclosed in Chinese Patent Application No. CN202223010206.1, the popping force during the popping process is equal to the force used during the closing and retracting process, which is inconvenient during use; moreover, during the closing and retracting process, it is also prone to misoperation, resulting in the situation where it is intended to close but rebounds instead.

[0003] For example, in the "A Door Closer with Two-way Buffering and Reset for Opening and Closing Doors" disclosed in Chinese Patent Application No. CN202110567145.X, the "A Micro Motion Cabinet Door Opener" disclosed in Chinese Patent Application No. CN202210163435.2, the "A Door-opening Pressing and Rebounding Device" disclosed in Chinese Patent Application No. CN202210870756.6, and the "A Cabinet Door Pressing-type Rebound Opening Device" disclosed in Chinese Patent Application No. CN202211164143.7. Although these types of rebounders solve the problem of the rebound of the cabinet door, and indirectly restore the rebounder to the closed and retracted state by using the lever principle during the closing process of the cabinet door. However, their structures are too complex, the manufacturing difficulty is large, and the production cost is high. Moreover, these designs mainly target the rebound opening, closing, and retracting between the cabinet door and the cabinet body, and have poor applicability to the rebound opening, closing, and retracting between the drawer and the cabinet body, unable to meet people's needs. In addition, the cabinet door or drawer is quite strenuous during the closing and retracting process, and the user experience is poor. Summary of the Invention

[0004] In order to solve the technical problems in the prior art that the structure of the rebounder is complex and the cabinet door or drawer is very strenuous during the closing and retracting process, the present invention provides a rebound device, including:

[0005] A popping member, the popping member includes a closed and retracted state and a popped state. When the first component moves in a direction approaching the second component so that the second component acts on the popping member, the popping member can switch from the closed and retracted state to the popped state, and at the same time, the popping member can react on the first component and can drive the first component to move in a direction away from the second component;

[0006] A pressing member, the pressing member includes a first engaging device, and the popping member includes a second engaging device;

[0007] The pressing member further includes a first connecting portion and a second connecting portion. The first connecting portion is used to rotatably connect the pressing member to the first member. The second connecting portion can abut against the second member. The linear distance from the first engaging device to the first connecting portion is less than the linear distance from the second connecting portion to the first connecting portion;

[0008] A first elastic member is used to apply an elastic force to the pressing member, so that the pressing member rotates around the first connecting portion, and when the second connecting portion contacts the second member, a thrust is generated on the second member; The first engaging device includes a third connecting portion capable of moving telescopically or displacing, and / or the second engaging device includes a third connecting portion capable of moving telescopically or displacing;

[0009] Wherein, when the ejecting member switches from the retracted state to the ejected 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 engaging device and / or at least a part of the second engaging device can drive the third connecting portion to move telescopically or displace, and then the first engaging device can move past the second engaging device to between the second member and the second engaging device;

[0010] Then, when an external force drives the first member to move in a direction approaching the second member, at least a part of the first engaging device and / or at least a part of the second engaging device can cooperate and contact connect with the third connecting portion, so that the pressing member drives the ejecting member to switch from the ejected state to the retracted state;

[0011] Then, when the second member drives the pressing member to continue to move, the first engaging device can move past the second engaging device, so that the second engaging device is located between the second member and the first engaging device.

[0012] Based on the above technical solution, the rebound device of the present invention is applied to the opening and closing of the cabinet door or drawer of furniture. For example, the first component is the cabinet body, and the second component is the cabinet door; or the first component is the drawer, and the second component is the cabinet body. Taking the drawer and the cabinet body as an example, when the drawer is closed, the ejector is in a retracted state. After an external force presses or pushes the drawer panel, the ejector switches from the retracted state to the ejected state. The ejector can act on the back panel or other parts of the cabinet body and then react on the drawer and can drive the drawer to move away from the back panel of the cabinet body. At this time, the first elastic member drives the pressing member to rotate, and the second connecting portion moves relative to the drawer towards the position of the back panel of the cabinet body; through the setting of the movable telescopic or displacement of the third connecting portion, the first matching device can move past the second matching device to between the back panel of the cabinet body and the second matching device. The concept is ingenious, and the problem is solved at low cost with a simple structure.

[0013] Then, when closing the drawer, an external force pushes the drawer towards the back panel of the cabinet body. The back panel of the cabinet body or other parts can abut against the second connecting portion to cause the pressing member to rotate and at least a part of the first matching device and / or at least a part of the second matching device to be able to cooperate and contact connect with the third connecting portion, so that the pressing member drives the ejector to switch from the ejected state to the retracted state. Since the straight-line distance from the first matching device to the first connecting portion is less than the straight-line distance from the second connecting portion to the first connecting portion, according to the lever principle, the external force used to drive the ejector to switch from the ejected state to the retracted state by the pressing member is less than the elastic force of the ejector from the retracted state to the ejected state, making the drawer more labor-saving and smoother during the closing process and improving the user experience.

[0014] Then, when the second component drives the pressing member to continue moving, the first matching device can move past 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 cooperate and contact connect with the third connecting portion, so that the second matching device is located between the second component and the first matching device. The concept is ingenious, and the problem is solved at low cost with a simple structure.

[0015] In addition, through at least a part of the matching device and / or at least a part of the second matching device being able to cooperate and contact connect with the third connecting portion, when the cabinet door or drawer drives the ejector to switch from the ejected state to the retracted state during the closing process, the cabinet door or drawer can not directly contact the ejector, reducing the risk of damage to the ejector and increasing the service life of the ejector. 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 matching device includes an avoidance space formed on the pressing member, and / or, the second matching device includes an avoidance space formed on the ejector;

[0017] When an external force drives the first component to move in a direction approaching the second component, at least a part of the first engaging device and / or the second engaging device can abut against the third connecting portion to drive the ejecting member to switch from the ejected 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 engaging device can cross over the second engaging device, and the second engaging device is located between the second component and the first engaging device.

[0018] For example, the second engaging device includes a third connecting portion capable of moving telescopically or displacing, and the first engaging device includes an avoidance space formed on the pressing member; when an external force drives the first component to move in a direction approaching the second component, at least a part of the first engaging device can abut against the third connecting portion to drive the ejecting member to switch from the ejected 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 engaging device can cross over the second engaging device, and the second engaging device is located between the second component and the first engaging device. When the first component moves in a direction approaching the second component, the pressing member will rotate as the first component moves, and a part of the pressing rod can push the third connecting portion to switch the ejecting member from the ejected state to the retracted state. By providing the avoidance space, after the ejecting member switches to the retracted state, the third connecting portion can pass through the avoidance space so that the pressing member can successfully cross over the third connecting portion, and the second engaging device is located between the second component and the first engaging device; then, when the first component is pressed to switch the ejecting member from the retracted state to the ejected state, the second engaging position is located between the first engaging position and the second component. Therefore, when the ejecting member ejects, the movement of the ejecting member is not affected by the pressing rod, and the movement of the first component is smoother. By using the rotation of the pressing member relative to the first component and / or the ejecting member, when the pressing member rotates to a specific position, the first engaging device and the second engaging device can be misaligned and separated, with a clever concept, and the problem is solved at low cost with a simple structure. In addition, when the first engaging device includes a third connecting portion capable of moving telescopically or displacing, and the second engaging device includes an avoidance space formed on the pressing member, the cooperation principle is the same as the above solution and will not be elaborated here.

[0019] It should be noted that the setting of the avoidance space is only one way for the first engaging device and the second engaging device to be misaligned and separated. This patent is not limited to this way. For example, other components can also be provided to abut against the first engaging device and / or the second engaging device so that the first engaging device is misaligned and separated from the second engaging device at a specific position.

[0020] In some embodiments, at least one side surface of the avoidance space is an arc surface or an inclined surface, so that the separation of the first fitting device and the second fitting device is smoother.

[0021] In some embodiments, a third elastic member is connected to the third connecting portion; a first surface is formed on the third connecting portion, and the first surface is an inclined surface or an arc surface;

[0022] When the second fitting device is located between the second member and the first fitting device and the first member moves away from the second member, at least a part of the first fitting device can act on the first surface of the second fitting device and cause the third elastic member of the second fitting device to deform so that the first fitting device can cross the third connecting portion located on the second fitting device, and the first fitting device is located between the second member and the second fitting device. After the first fitting device crosses the first surface, the third elastic member can drive the third connecting portion located on the second fitting device to return to its original state; and / or,

[0023] When the second fitting device is located between the second member and the first fitting device and the first member moves away from the second member, at least a part of the second fitting device can act on the first surface of the first fitting device and cause the third elastic member of the first fitting device to deform so that the second fitting device can cross the third connecting portion located on the first fitting device, and the first fitting device is located between the second member and the second fitting device. After the second fitting device crosses the first surface, the third elastic member can drive the reset of the third connection located on the second fitting device. The concept is ingenious, and the problem is solved at low cost with a simple structure.

[0024] In some embodiments, the first elastic member includes a torsion spring. At least a part of the pressing member passes through the torsion spring and is rotatably connected to the first member. The torsion spring can apply an elastic force to the pressing member so as to generate a thrust on the second member when the pressing member contacts the second member; and / or, the torsion spring can apply an elastic force to the pressing member so that at least a part of the first fitting device and / or at least a part of the second fitting device can drive the third connecting portion to perform active telescoping or displacement, and then the first fitting device can cross the second fitting device and move between the second member and the second fitting device.

[0025] In some embodiments, it further includes at least one limiting portion, and the limiting portion is used to limit the rotation range of the pressing member relative to the first member. So that at least in one embodiment, when the first engaging device can move past the second engaging device to between the second member and the second engaging device for the first time, the pressing member stops rotating, so that the first engaging device and / or the second engaging device can be in a state of mating contact connection or a state close to mating contact connection with the third connecting portion; when the second member moves from a relatively far position relative to the pressing member towards the pressing member and collides with the pressing member, because the first engaging device and / or the second engaging device can be in a state of mating contact connection or a state close to mating contact connection with the third connecting portion, it can minimize the damage to the first engaging device and / or the second engaging device and the third connecting portion, increase the service life, and at the same time, the user experience is better.

[0026] In some embodiments, the second connecting portion is formed with a rolling portion, and the rolling portion is used to move on the second member in a rolling manner. To reduce the friction between the rolling portion and the second member, make the furniture member quieter during the opening and closing process, and at the same time, reduce the possible damage caused when the second member collides with the second connecting portion, and increase the service life.

[0027] In some embodiments, it further includes a reciprocating movement mechanism, and the reciprocating movement mechanism is used to smoothly switch the ejecting member between the retracted state and the ejected state.

[0028] In some embodiments, the reciprocating movement mechanism includes a first abutting portion, a first guiding groove and a fourth elastic member. The first guiding groove includes a first retracting section and a first ejecting section. The ejecting member includes a first engaging portion, and the first engaging portion is disposed in the first guiding groove;

[0029] When at least a part of the first engaging device and / or at least a part of the second engaging device are in mating contact connection with the third connecting portion, and while switching the ejecting member from the ejected state to the retracted state, the first engaging portion falls into the first retracting section, the first engaging device moves past the second engaging device, the ejecting member compresses the fourth elastic member, and the first engaging portion abuts against the first abutting portion, so that the ejecting member enters the retracted state;

[0030] Then, when the first member directly acts on the ejecting member in a direction approaching the second member, the first engaging portion can enter the first ejecting section and disengage from the first abutting portion, so that the ejecting member can act on the second member under the drive of the fourth elastic member and can react to drive the first member to move in a direction away from the second member.

[0031] In some embodiments, the reciprocating movement mechanism includes a second engaging portion and a fourth elastic member. The ejecting member includes a second abutting portion and a second guiding groove. The second guiding groove includes a second converging section and a second ejecting section. The second engaging portion is disposed in the second guiding groove;

[0032] When the second abutting portion abuts against the second engaging portion and the ejecting member is switched from the ejecting state to the converging state, the second engaging portion falls into the second converging section, the first engaging device passes over the second engaging device, the ejecting member compresses the fourth elastic member, and the second engaging portion abuts against the second abutting portion to enable the ejecting member to enter the converging state;

[0033] Then, when the first member directly acts on the ejecting member in a direction approaching the second member, the second engaging 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 drive of the fourth elastic member and can react to drive the first member to move in a direction 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 converging 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 pressing and rebounding.

[0035] In some embodiments, a buffer assembly is included. When the first engaging device moves in a direction away from the second member with respect to the second engaging device and passes over the second engaging device, the buffer assembly is used to enable the first member to slowly move in a direction approaching the second member. After the ejecting member returns to the converging state, the first member can continue to converge and reset relative to the second member in a buffered manner, which is convenient for the user to use the furniture member, and at the same time is more noise-reducing and has a better experience. Adding a buffer assembly on the basis of the rebounding device enables the furniture member with the functions of rebounding and buffering to be completed with a simple structure, and solves the problem at low cost.

[0036] In some embodiments, a second elastic member is included. After the first engaging device comes into contact and cooperation with the first engaging device and drives the ejecting member to be switched from the ejecting state to the converging state, the second elastic member can drive the second member to move in a direction approaching the first member; at this time, the force of the second elastic member driving the second member to move in a direction approaching the first member is greater than the reaction force of the first elastic member on it and the resistance of the buffer assembly.

[0037] In some embodiments, the pressing member includes a first swing arm and a second swing arm connected to each other. The second connecting portion is located on the second swing arm, and the first engaging device is located on the second swing arm.

[0038] In some embodiments, it further includes 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, so as to make it more convenient to mount the rebounding device on the member and make the structure more firm and stable.

[0039] In some embodiments, at least two adjusting slots are formed on the mounting plate, and the adjusting slots are used to adjust the distance between the rebounding device and the first member or the second member. Description of the Drawings

The first connecting portion 15 is used to rotatably connect the pressing member 1 to the first member 100. The second connecting portion 16 can abut against the second member 200. The straight-line distance from the first engaging device 13 to the first connecting portion 15 is less 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 an elastic force to the pressing member 1 so that the pressing member 1 rotates around the first connecting portion 15 and generates a thrust on the second member 200 when the second connecting portion 16 contacts the second member 200; the first engaging device 13 includes a third connecting portion 311 that can move telescopically or displace, and / or the second engaging device 31 includes a third connecting portion 311 that can move telescopically or displace; wherein, when the pop-up member 3 switches from the retracted state to the popped state to drive the first member 100 to move in a direction away from the second member 200, the first elastic member 2 drives the pressing member 1 to rotate so that at least a part of the first engaging device 13 and / or at least a part of the second engaging device 31 can drive the third connecting portion 311 to move telescopically or displace. After that, the first engaging device 13 can move past the second engaging device 31 and move between the second member 200 and the second engaging device 31; then, when an external force drives the first member 100 to move in a direction approaching the second member 200, at least a part of the first engaging device 13 and / or at least a part of the second engaging device 31 can cooperate and contact with the third connecting portion 311 so that the pressing member 1 drives the pop-up member 3 to switch from the popped state to the retracted state; then, when the second member 200 drives the pressing member 1 to continue moving, the first engaging device 13 can move past the second engaging device 31 so that the second engaging device 31 is located between the second member 200 and the first engaging device 13.

[0082] Among them, the rebound device 10 of the present invention is used for the opening and closing of furniture such as cabinet doors or drawers. The present invention does not limit the specific structures of the first member 100 and the second member 200. For example, when the first member 100 is a cabinet body and the second member 200 is a cabinet door; or when the first member 100 is a drawer and the second member 200 is a cabinet body; or conversely, the first member 100 is a cabinet door and the second member 200 is a cabinet body. The movements of the first member 100 and the second member 200 are relative, that is, an external force drives the first member 100 to move towards the second member 200, which can also be understood as an external force driving the second member 200 to move towards the first member 100. When the first member 100 or the second member 200 is fixed, when an external force acts on one of the first member 100 and the second member 200, the external force can react on the other of the first member 100 or the second member 200. For example, when the second member 200 is fixed and an external force acts on the second member 200, the force acting on the second member 200 can react on the first member 100 to cause the first member 100 and the second member 200 to separate relatively, so that the first member 100 is in a relatively open state.

[0083] For example, in this embodiment, the first member 100 can be a drawer, and the second member 200 can be the back panel or other parts of the cabinet body; for example, the first connecting portion 15 rotatably mounts the pressing member 1 on the drawer, and the ejecting member 3 is also mounted on the drawer. The second connecting portion 16 of the pressing member 1 is connected or abutted or closely abutted to the back panel of the cabinet body. When the ejecting member 3 is in the retracted state, an external force drives the drawer to move towards the direction close to the back panel of the cabinet body. After the ejecting member 3 abuts against the back panel of the cabinet body, it drives the ejecting member 3 to switch from the retracted state to the ejected state. The ejecting member 3 generates a thrust force on the back panel of the cabinet body. Since the back panel of the cabinet body is fixed, the thrust force reacts on the drawer and causes the drawer and the back panel of the cabinet body to separate relatively, so that the drawer is in a relatively open state.

[0084] Another example is that in this embodiment, the first member 100 can be a cabinet body and the second member 200 can be a cabinet door; for example, the first connecting portion 15 rotatably mounts the pressing member 1 on the cabinet body, and the ejecting member 3 is also mounted on the cabinet body. The second connecting portion 16 of the pressing member 1 is connected or abutted to the cabinet door. When the ejecting member 3 is in the retracted state, when an external force acts on the cabinet door, it drives the cabinet door to move towards the direction close to the cabinet body. After the ejecting member 3 abuts against the cabinet door, it drives the ejecting member 3 to switch from the retracted state to the ejected state. The ejecting member 3 generates a thrust force on the cabinet door, pushing the cabinet door and the cabinet body to separate relatively, so that the cabinet door is in a relatively open state.

[0085] Among them, when the ejecting member 3 is in the retracted state, the first case is the normal use state: when the first member 100 and the second member 200 are close to each other (the state of closing the door or drawer), the second member 200 and the ejecting member 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 ejecting member 3; the second case is the abnormal use state, that is, the first member 100 and the second member 200 can be in a separated state (the state of opening the door or drawer); in either case, as long as an external force drives the first member 100 to move in the direction approaching the second member 200 and can drive the ejecting member 3 to abut against the second member 200, so that after the ejecting member 3 abuts against the second member 200, the ejecting member 3 gradually switches from the retracted state to the ejected state, the ejecting member 3 can push the second member 200 to move (or in other words, reactively push the first member 100 to move), so that the first member 100 and the second member 200 are relatively separated, so that the furniture is in the open state.

[0086] The first connecting portion 15 can be, for example, a rotating shaft, a sphere or other rotating body structure. A part of the pressing member 1 is rotatably arranged on the first member 100 through the first connecting portion 15. Among them, the pressing member 1 can be directly rotated with the first member 100 through the first connecting portion 15, or the pressing member 1 can be first rotatably connected to the box body, the shell or the mounting plate 20, and then the box body, the shell or the mounting plate 20 is fixed on the first member 100, so that the pressing member 1 is indirectly rotated with the first member 100.

[0087] The second connecting portion 16 can be, for example, one end of the pressing member 1, a part of the pressing member 1, or a component mounted on the pressing member 1.

[0088] The embodiment of the present invention does not limit the shape or structure of the third connecting portion 311, and the embodiment of the present invention does not limit the direction of the active telescoping or displacement of the third connecting portion 311. For example, the third connecting portion 311 can be a block or a column, for example, the third connecting portion 311 can perform active telescoping or displacement in the up-down direction, left-right direction or front-back direction relative to the pressing member 1, and / or the third connecting portion 311 can perform active telescoping or displacement in the up-down direction, left-right direction or front-back direction relative to the ejecting member 3.

[0089] 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 and connected with the second engaging device 31 when the first engaging device 13 and the second engaging device 31 are in mating contact connection to drive the ejecting member 3 to switch from the ejected 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 towards the second member 200, the second member 200 drives the pressing member 1 to rotate around the first connecting portion 15 through 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 lever principle, the thrust force of the external force acting on the first member 100 to cause the ejecting member 3 to switch from the ejected state to the retracted state is less than the force exerted by the ejecting member 3 on the first member 100 when the ejecting member 3 switches from the retracted state to the ejected state, making the process of the external force pushing the first member 100 closer to the second member 200 more labor-saving and compliant, thus improving the user experience.

[0090] In some embodiments, the second connecting portion 16 abuts against the cabinet body back panel. When an external force drives the first member 100, such as a drawer, to move towards the second member 200, such as the cabinet body back panel, it can drive the ejecting member 3 to move and then abut against the cabinet body back panel, so that after the ejecting member 3 abuts against the cabinet body back panel, the ejecting member 3 gradually switches from the retracted state to the ejected state; at the moment when the ejecting member 3 abuts against the cabinet body back panel, the second engaging device 31 is located between the first engaging device 13 and the cabinet body back panel.

[0091] As the ejecting member 3 gradually switches from the retracted state to the ejected state and can be set with sufficient elastic force to continuously push the drawer in a direction away from the cabinet back plate until the drawer is fully opened or nearly fully opened. During this process, it can be set that when the drawer moves a certain distance away from the cabinet back plate and the ejecting member 3, the pressing member 1 rotates under the action of the first elastic member 2 to the position where the first engaging device 13 and the second engaging device 31 coincide. Through the movable telescopic or displacement setting of the third connecting portion 311 on the first engaging device 13 and / or the second engaging device 31, the first engaging device 13 can move past the second engaging device 31 to between the cabinet back plate and the second engaging device 31. During this process, the second connecting portion 16 can be kept in close contact with the cabinet back plate under the action of the first elastic member 2. In the case of abnormal use, during the process of the ejecting member 3 switching from the retracted state to the ejected state after abutting against the cabinet back plate, the external force applied by the user may not stop after the moment when the ejecting member 3 abuts against the cabinet back plate, but may continuously or for a certain period apply an external force to the drawer during the process of the ejecting member 3 switching from the retracted state to the ejected state after abutting against the cabinet back plate, so that when the drawer stops, the second engaging device 31 is still located between the first engaging device 13 and the cabinet back plate. In this case, the user can manually pull open the drawer so that the first engaging device 13 can move past the second engaging device 31 to between the cabinet back plate and the second engaging device 31, or the user can press to close the drawer so that the cabinet back plate directly abuts against the ejecting member 3 to switch the ejecting member 3 from the ejected state to the retracted state. This design has a high error tolerance and will not cause additional damage to the device in the case of abnormal use.

[0092] Under normal use conditions, then, 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 a direction approaching the cabinet body back panel, the pressing member 1 rotates to the mating connection joint between the first mating device 13 and the second mating device 31 under the action of the cabinet body back panel through the third connection portion 311. At this time, it can be that the first mating device 13 is in mating contact connection with the third connection portion 311 located on the second mating device 31, or the second mating device 31 is in mating contact connection with the third connection portion 311 located on the first mating device 13, or the third connection portion 311 on the first mating device 13 is in mating contact connection with the third connection portion 311 located on the second mating device 31. It is assumed that the external force is large enough so that the pressing member 1 can drive the ejecting member 3 to switch from the ejected state to the retracted state. In the abnormal situation where the external force is not large enough for the pressing member 1 to drive the ejecting member 3 to switch from the ejected state to the retracted state, the elastic force of the ejecting member 3 acts on the first mating device 13 through the second mating device 31 so that the ejecting member 3 rebounds against the cabinet body back panel through the second connection portion 16, thereby causing the drawer to move towards the open state. In this case, the user only needs to apply another sufficient external force to the drawer. Then, it is assumed that the cabinet body back panel continues to drive the pressing member 1 to continue moving, and the first mating device 13 can cross over the second mating device 31 so that the first mating device 13 and the second mating device 31 are separated, that is, at least a part of the first mating device 13 and / or at least a part of the second mating device 31 can no longer be in mating contact connection with the third connection portion 311, so that the second mating device 31 is located between the second member 200 and the first mating device 13, and the drawer can be driven to the closed state.

[0093] In addition, in the case of abnormal use, when the drawer is in the 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 rebounding device 10 is equivalent to not being used. Therefore, this abnormal use situation does not cause damage to the furniture and the rebounding device 10 either, and this design has a high fault tolerance rate.

[0094] In addition, through the fact that at least a part of the first mating device 13 and / or at least a part of the second mating device 31 can be in mating contact connection with the third connection portion 311, when the drawer drives the ejecting member 3 to switch from the ejected state to the retracted state during the closing process, the cabinet body back panel does not directly contact the ejecting member 3, reducing the risk of damage to the ejecting member 3 and increasing the service life of the ejecting member 3. The rebounding device 10 of the present invention has a simple structure, is easy to manufacture, and has a relatively low manufacturing cost.

[0095] In some embodiments, the first engaging device 13 includes an avoidance space 131 formed on the pressing member 1, and / or, the second engaging device 31 includes an avoidance space 131 formed on the ejecting member 3; when an external force drives the first member 100 to move in a direction approaching the second member 200, at least a part of the first engaging device 13 and / or the second engaging device 31 can abut against the third connecting portion 311 to drive the ejecting member 3 to switch from the ejected state to the retracted state; then when the second member 200 drives the pressing member 1 to continue moving, the third connecting portion 311 can enter the avoidance space 131 so that the first engaging device 13 can cross over the second engaging device 31, with the second engaging device 31 located between the second member 200 and the first engaging device 13. The avoidance space 131 can be a groove or a notch or a slot hole structure. Among them, the avoidance space 131 and the third connecting portion 311 are opposite to each other. For example, the first engaging device 13 can include the avoidance space 131 and the second engaging device 31 can include the third connecting portion 311; or for another example, the second engaging device 31 can include the avoidance space 131 and the first engaging device 13 can include the third connecting portion 311; or for yet another example, both the first engaging device 13 and the second engaging device 31 have the third connecting portion 311, and when the pressing member 1 rotates to a specific position, the third connecting portions 311 of the first engaging device 13 and the second engaging device 31 can be offset from each other to form the avoidance space 131 therebetween. Now, an example is given: for example, the second engaging device 31 includes a third connecting portion 311 that can move telescopically or displaceably, and the first engaging device 13 includes the avoidance space 131 formed on the pressing member 1; when an external force drives the first member 100 such as a drawer to move in a direction approaching the second member 200 such as a cabinet back panel, at least a part of the first engaging device 13 can abut against the third connecting portion 311 to drive the ejecting member 3 to switch from the ejected state to the retracted state; then when the cabinet back panel drives the pressing member 1 to continue moving, the third connecting portion 311 can enter the avoidance space 131 so that the first engaging device 13 can cross over the second engaging device 31, with the second engaging device 31 located between the second member 200 and the first engaging device 13. Refer to Figures 22 - 25, when the first component 100, such as a drawer, moves in a direction approaching the second component 200, such as the back panel of a cabinet body, the pressing member 1 will rotate as the first component 100 moves. A part of the pressing member 1 can push the third connecting portion 311, so that the ejecting member 3 switches from the ejecting state to the retracting state. By providing the avoidance space 131, after the ejecting member 3 switches from the ejecting state to the retracted state, the third connecting portion 311 can pass through the avoidance space 131, so that the pressing member 1 can successfully cross the third connecting portion 311, and the second engaging device 31 is located between the second component 200 and the first engaging device 13. Then, when the drawer is pressed to switch the ejecting member 3 from the retracted state to the ejecting state, the second engaging position is located between the first engaging position and the back panel of the cabinet body. Therefore, when the ejecting member 3 ejects, the movement of the ejecting member 3 is not affected by the pressing rod, and the movement of the drawer is smoother. By using the rotation of the pressing member 1 relative to the drawer and / or the ejecting member 3, when the pressing member 1 rotates to a specific position, the first engaging device 13 and the second engaging device 31 can be misaligned and separated. The concept is ingenious, and the problem is solved at low cost with a simple structure. In addition, the cooperation principles of the other two cases are the same as the above solution and will not be elaborated here.

[0096] In some embodiments, at least one side surface of the avoidance space 131 is an arc surface or an inclined surface, so that the separation of the first engaging device 13 and the second engaging device 31 is smoother. In particular, when the side surface of the avoidance space 131 is an arc surface, stress concentration can be avoided, the risk of wear of the pressing member 1 can be reduced, and the service life of the pressing member 1 can be extended.

[0097] It should be noted that the setting of the avoidance space 131 is only one way for the first engaging device 13 and the second engaging device 31 to produce misalignment separation. This patent is not limited to this way. For example, other components can also be provided to abut against the first engaging device 13 and / or the second engaging device 31 when the pressing member 1 rotates to a specific position, so that the first engaging device 13 produces misalignment separation from the second engaging device 31 at a specific position. For example, the ejecting member 3 further includes a driving portion for driving the third connecting portion 311 to move telescopically or displace. The driving portion is, for example, an inverted buckle or a hook portion. When an external force drives the first member 100 to move in a direction approaching the second member 200, at least a part of the first engaging device 13 can abut against the third connecting portion 311. When driving the ejecting member 3 to switch from the ejecting state to the retracted state, at least a part of the first engaging device 13 acts on the driving portion, so that the driving portion drives the third connecting portion 311 to retract or displace, so that the first engaging device 13 can cross over the third connecting portion 311, that is, the pressing member 1 successfully crosses over the third connecting portion 311, and the second engaging device 31 is located between the second member 200 and the first engaging device 13. Another example is that the ejecting member 3 further includes a driving portion capable of driving the first engaging device 13 and / or the second engaging device 31 at a specific position. The driving portion is, for example, an inverted buckle or a hook portion. When an external force drives the first member 100 to move in a direction approaching the second member 200, at least a part of the first engaging device 13 can abut against the second engaging device 31. After driving the ejecting member 3 to switch from the ejecting state to the retracted state, the driving portion can act on the first engaging device 13 and / or the second engaging device 31, so that the first engaging device 13 and the second engaging device 31 produce misalignment separation, so that the first engaging device 13 can cross over the second engaging device 31, and the second engaging device 31 is located between the second member 200 and the first engaging device 13. The cooperation principles in other cases are similar to the above solution ideas, as long as the first engaging device 13 and the second engaging device 31 can produce misalignment separation at a specific position, which will not be elaborated here.

[0098] In some embodiments, a third elastic member 312 is connected to the third connecting portion 311; a first surface 313 is formed on the third connecting portion 311, and the first surface 313 may be an inclined surface or a curved surface; wherein, 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 away from the second member 200, at least a part of the first engaging device 13 can act on the first surface 313 of the second engaging device 31 and deform the third elastic member 312 of the second engaging device 31 so that the first engaging device 13 can cross the third connecting portion 311 of the second engaging device 31 and the first engaging device 13 is located between the second member 200 and the second engaging device 31. After the first engaging device 13 crosses 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. As Figure 25 shown, when the first member 100 is pressed to switch the ejecting member 3 from the retracted state to the ejected state, the second engaging position is located between the first engaging position and the second member 200. Therefore, when the ejecting member 3 is ejected, the movement of the ejecting member 3 is not affected by the pressing member 1. The first engaging 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 a curved surface, it is assumed that the first elastic member 2 applies sufficient elastic force to the pressing member 1 so that the lateral thrust applied by the first engaging device 13 to the third connecting portion 311 can be converted into a vertical pressure. Therefore, the first engaging device 13 can gradually press down the third connecting portion 311 during the movement until the first engaging device 13 completely crosses the third connecting portion 311. Then, the third elastic member 312 will push the third connecting portion 311 upward, ensuring that when the first member 100 moves in the direction close to the second member 200 subsequently, the first engaging device 13 can contact and cooperate with the second engaging device 31 to drive the ejecting member 3 to switch from the ejected state to the retracted state. In this embodiment, by using the cooperation of the third elastic member 312 and the inclined surface or the curved surface, the telescopic movement of the third connecting portion 311 can be made smoother. Furthermore, when the first member 100 moves away from the second member 200, the first engaging device 13 can smoothly cross the second engaging device 31, so that when the first member 100 moves away from the second member 200, the first member 100 will not get 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 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 so that the second engaging device 31 can cross the third connecting portion 311 of the first engaging device 13 and place the first engaging device 13 between the second member 200 and the second engaging device 31. After the second engaging device 31 crosses 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 may be a case where the first engaging device 13 has a first surface 313 and the second engaging device 31 also has a first surface 313. The working principle refers to the combination of the above two embodiments and will not be elaborated here.

[0100] In some embodiments, the first elastic member 2 includes a torsion spring. At least a part of the pressing member 1 can pass through the torsion spring and be rotatably connected to the first member 100. The torsion spring can apply an elastic force to the pressing member 1 so as to generate a thrust 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 so that at least a part of the first engaging device 13 and / or at least a part of the second engaging device 31 can drive the third connecting portion 311 to undergo active expansion / contraction or displacement, and then the first engaging device 13 can cross the second engaging device 31 and move between the second member 200 and the second engaging device 31. The torsion spring can be connected to the position of the first connecting portion 15. When the first member 100 and the second member 200 approach each other relatively, the torsion spring can apply an elastic force to the pressing member 1 so that the first member 100 and the second member 200 tend to separate relatively, so that the second connecting portion 16 remains in contact with the second member 200; the torsion spring is set to have sufficient force so that at least a part of the first engaging device 13 and / or at least a part of the second engaging device 31 can drive the third connecting portion 311 to undergo active expansion / contraction or displacement. In other embodiments, the first elastic member 2 can also be other elastic objects.

[0101] In some embodiments, the embodiment of the present invention further includes at least one limiting portion 5. The limiting portion 5 is used to limit the rotation range of the pressing member 1 relative to the first member 100. The limiting portion 5 is, for example, a convex or bump structure. The limiting portion 5 can be on the first member 100 or the rebounding device 10, or the limiting portion 5 is the elastic limit of the first elastic member 2, and there is no limitation here. The limiting portion 5 is used to limit the rotation range of the pressing member 1 around the first connecting portion 15. For example, in at least one of the embodiments, it can be the first time when the first engaging device 13 just moves past the second engaging device 31 and moves between the second member 200 and the second engaging device 31, the limiting portion 5 causes the pressing member 1 to stop rotating further, so that the first engaging device 13 and / or the second engaging device 31 can be in a state of being in mating contact connection or a state close to mating contact connection with the third connecting portion 311; when the second member 200 moves from a relatively far position relative to the pressing member 1 towards the pressing member 1 and collides with the pressing member 1, because the first engaging device 13 and / or the second engaging device 31 can be in a state of being in mating contact connection or a state close to mating contact connection with the third connecting portion 311, it can minimize the damage caused by the collision between the first engaging device 13 and / or the second engaging device 31 and the third connecting portion 311. While increasing the service life, the user experience is also better.

[0102] In some embodiments, the second connecting portion 16 is formed with a rolling portion 14. The rolling portion 14 is used to move on the second member 200 in a rolling manner. The rolling portion 14 is rotatably provided on the pressing member 1, so that the contact between the pressing member 1 and the second member 200 is a rolling contact. The rolling manner is used to reduce the friction between the rolling portion 14 and the second member 200, make the furniture member quieter during the opening and closing process, and at the same time, reduce the possible damage caused when the second member 200 collides with the second connecting portion 16, and increase the service life.

[0103] In some embodiments, the rebounding device 10 of the embodiment of the present invention further includes a reciprocating movement mechanism 4. The reciprocating movement mechanism 4 is used to smoothly switch the ejecting member 3 between the retracted state and the ejected state. When the ejecting member 3 is in the retracted state, the reciprocating movement mechanism 4 is used to keep the ejecting member 3 in the retracted state.

[0104] In some embodiments, the reciprocating movement mechanism 4 includes a first abutting portion 41, a first guiding groove 42, and a fourth elastic member 43. The first guiding groove 42 includes a first converging section 421 and a first ejecting section 422. The ejecting member 3 includes a first engaging portion 32 which is disposed in the first guiding groove 42. When at least a part of the first engaging device 13 and / or at least a part of the second engaging device 31 are in mating contact connection with the third connecting portion 311 and the ejecting member 3 is switched from the ejecting state to the converging state, the first engaging portion 32 falls into the first converging section 421, the first engaging device 13 passes over the second engaging device 31, the ejecting member 3 compresses the fourth elastic member 43, and the first engaging portion 32 abuts against the first abutting portion 41 to enable the ejecting member 3 to enter the converging state. Then, when the first member 100 directly acts on the ejecting member 3 in the direction approaching the second member 200, the first engaging portion 32 can enter the first ejecting 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 drive of the fourth elastic member 43 and can react to drive the first member 100 to move away from the second member 200 in the opposite direction. For example, the first abutting portion 41 has a convex structure and is disposed in the first guiding groove 42. The first guiding groove 42 forms a first converging section 421 and a first ejecting section 422 through the first abutting portion 41. The first engaging portion 32 can be in a hook shape or a snap structure. When the ejecting member 3 is in the converging state, the first engaging portion 32 cooperates with the first abutting portion 41 to abut against each other, so that the ejecting member 3 can maintain the converging state. When the ejecting member 3 is switched from the converging state to the ejecting state, the first engaging portion 32 disengages from the first abutting portion 41 to switch the ejecting member 3 to the ejecting state, so that the ejecting member 3 can extend and retract smoothly.

[0105] In some other embodiments, the reciprocating movement mechanism 4 includes a second engaging portion and a fourth elastic member 43. The ejecting member 3 includes a second abutting portion and a second guiding groove. The second guiding groove includes a second converging section and a second ejecting section. The second engaging portion is disposed in the second guiding groove. When the second abutting portion abuts against the second engaging portion and the ejecting member 3 is switched from the ejecting state to the converging state, the second engaging portion falls into the second converging section, the first engaging device 13 passes over the second engaging device 31, the ejecting member 3 compresses the fourth elastic member 43, and the second engaging portion abuts against the second abutting portion to enable the ejecting member 3 to enter the converging state. Then, when the first member 100 directly acts on the ejecting member 3 in the direction approaching the second member 200, the second engaging portion can enter the second ejecting section and disengage from the second abutting portion, so that the ejecting member 3 can act on the second member 200 under the drive of the fourth elastic member 43 and can react to drive the first member 100 to move away from the second member 200 in the opposite direction. For the principle of this movement, please refer to the above, and the description is omitted here.

[0106] In some embodiments, the ejecting member 3 is connected to an adjusting portion 33. When the ejecting member 3 is in the retracted state and the second member 200 continues to approach the first member 100, the adjusting portion 33 is configured to adjust the relative position between the ejecting member 3 and the second member 200. For example, the adjusting portion 33 is disposed between the ejecting member 3 and the second member 200. The adjusting portion 33 and the ejecting member 3 may be connected by a threaded connection or a sliding telescopic structure. By adjusting the distance between the ejecting member 3 and the second member 200 through the adjusting portion 33, the adjusting portion 33 of the ejecting member 3 may be brought into abutment or close abutment with the second member 200 to facilitate pressing and rebounding.

[0107] In some embodiments, a buffer assembly is included. When the first engaging device 13 moves in a direction away from the second member 200 of the second engaging device 31 and crosses the second engaging device 31, the buffer assembly is configured to enable the first member 100 to move slowly in a direction approaching the second member 200, or the buffer assembly is configured to enable the first member 100 to maintain a tendency to move in a direction approaching the second member 200, or the buffer assembly is configured to apply a pulling force to the first member 100 to approach the second member 200. After the ejecting member 3 returns to the retracted state, the first member 100 can automatically continue to retract and reset relative to the second member 200 in a buffered manner through the buffer assembly, facilitating the user's use of the furniture member, while being more noise-reducing and providing a better experience. Adding a buffer assembly on the basis of the rebounding device 10 enables the furniture member with the rebounding and buffering functions to be completed with a simple structure, solving the problem at low cost.

[0108] In some specific embodiments, for example, taking the first member 100 as a drawer, the pressing member 1 and the ejecting member 3 are installed on the drawer, and the second member 200 as a cabinet body as an example, the buffer assembly may be a buffer slide rail for installing the drawer on the cabinet body. It is set that the elastic force for the ejecting member 3 to gradually switch from the retracted state to the ejected state is greater than the pulling force of the buffer of the buffer slide rail for the drawer to tend to the closed state. It is set that the stroke of the buffer is greater than or equal to the drawer stroke from when the first engaging device 13 and the second engaging device 31 are misaligned and separated to when the drawer is completely closed. When an external force drives the first member 100, such as a drawer, to move in the direction approaching the second member 200, such as the back panel of the cabinet body, and can drive the ejecting member 3 to move and abut against the back panel of the cabinet body, so that after the ejecting member 3 abuts against the back panel of the cabinet body, the ejecting member 3 can break through the pulling force of the buffer and gradually switch from the retracted state to the ejected state; and it is set that during the process of the ejecting member 3 switching from the retracted state to the ejected state, it can have sufficient elastic force to push the drawer to continuously move in the direction away from the back panel of the cabinet body until it exceeds the stroke of the buffer and the drawer is completely opened or nearly completely opened. At the same time, during this process, when the drawer moves a certain distance away from the back panel of the cabinet body and the ejecting member 3, the pressing member 1 rotates under the action of the first elastic member 2 to the position where the first engaging device 13 and the second engaging device 31 coincide. Through the movable telescopic or displaceable setting of the third connecting portion 311 on the first engaging device 13 and / or the second engaging device 31, the first engaging device 13 can move past the second engaging device 31 to between the back panel of the cabinet body and the second engaging device 31.

[0109] In a preferred case, the stroke of the ejecting member 3 when switching from the retracted state to the ejected state can be set to be greater than the stroke of the buffer. In a non-preferred case, when the stroke of the ejecting member 3 when switching from the retracted state to the ejected state is set to be less than or equal to the stroke of the buffer, in the case of abnormal use, during the process of the ejecting member 3 switching from the retracted state to the ejected state after the ejecting member 3 abuts against the cabinet body back panel, it is possible that the user does not stop applying an external force after the moment when the ejecting member 3 abuts against the cabinet body back panel, but applies an external force to the drawer continuously or for a certain period during the process of the ejecting member 3 switching from the retracted state to the ejected state after the ejecting member 3 abuts against the cabinet body back panel. As a result, when the drawer stops, the drawer can make the ejecting member 3 abut against the cabinet body back panel under the pulling force of the buffer assembly. At this time, the second engaging device 31 is still located between the first engaging device 13 and the cabinet body back panel. In this case, the user can manually pull open the drawer so that the first engaging device 13 can move past the second engaging device 31 to between the cabinet body back panel and the second engaging device 31, or the user can press to close the drawer so that the cabinet body back panel directly abuts against the ejecting member 3 to make the ejecting member 3 switch from the ejected state to the retracted state. This design has a high fault tolerance rate and will not cause additional damage to the device in the case of abnormal use. Then, in a 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 a direction approaching the cabinet body back panel, the stroke of the pressing member 1 rotating from the position where the third connecting portion 311 is under the action of the cabinet body back panel to the position where the first engaging device 13 and the second engaging device 31 are in mating contact connection to the fully closed state of the drawer 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 engaging device 13 and the second engaging device 31 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 in the direction of the cabinet body back panel to the position where the first engaging device 13 and the second engaging device 31 are in mating contact connection. In either case, when used normally, a sufficiently large external force can be set to push the drawer towards the closed state, that is, a sufficiently large external force can be set to drive the drawer to move in a direction approaching the cabinet body back panel so that the pressing member 1 can drive the ejecting member 3 to switch from the ejected state to the retracted state. In an abnormal situation where the external force is not large enough to enable the pressing member 1 to drive the ejecting member 3 to switch from the ejected state to the retracted state, the elastic force of the ejecting member 3 acts on the first engaging device 13 through the second engaging device 31 so that the rebounding force of the ejecting member 3 acts on the cabinet body back panel through the third connecting portion 311, thereby causing the drawer to move towards the open state. In this case, the user only needs to apply a sufficiently large external force to the drawer to close it again.

[0110] In addition, in a preferred case, the stroke of the buffer is greater than or equal to the drawer stroke from when the first engaging device 13 and the second engaging device 31 are misaligned and separated to when the drawer is fully closed. In a non-preferred case, the stroke of the buffer may also be less than the stroke from when the first engaging device 13 and the second engaging device 31 are misaligned and separated to when the drawer is fully closed, which will not be elaborated here.

[0111] In addition, in the case of abnormal use, when the drawer is in the 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 rebounding function is not used, and only the buffering function is used. Therefore, this abnormal use situation does not damage the furniture and the rebounding device 10 either, and this design has a high fault tolerance rate.

[0112] For another example, the first member 100 may be a cabinet body, the pressing member 1 and the ejecting member 3 are installed on the cabinet body, the second member 200 may be a cabinet door, and the buffer assembly may be a buffer hinge for mounting the cabinet door on the cabinet body.

[0113] 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 elaborated here.

[0114] In some embodiments, a second elastic member is included. After the first engaging device 13 is in contact and cooperation with the second engaging device 31 and drives the ejecting member 3 to switch from the ejected state to the retracted state, the second elastic member can drive the second member 200 to move in a direction approaching the first member 100; at this time, the force of the second elastic member driving the second member 200 to move in a direction approaching the first member 100 is greater than the reaction force of the first elastic member 2 on it and the resistance of the buffer assembly, so that the second member 200 approaches the first member 100 relatively slowly, achieving a buffering effect. The second elastic member is, for example, a spring or an elastic object. The buffering acting force generated by the buffer assembly is in the opposite direction to the acting force of the second elastic member. When the second member 200 moves in a direction approaching the first member 100 to a preset position, the resistance of the buffer assembly and the acting force of the first elastic member 2 are less than the acting force of the second elastic member, so that the second member 200 slowly approaches the first member 100 to close the door or the drawer.

[0115] In some embodiments, the pressing member 1 includes a first swing arm 11 and a second swing arm 12 connected to each other, a second connecting portion 16 is located on the second swing arm 12, and a first mating 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 about the first connecting portion 15, and the second connecting portion 16 generates a thrust on the second member 200 when in contact with the second member 200. In actual application, 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 the direction away from the second component 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 the external force drives the first component 100 to move in the direction close to the second component 200, the second component 200 acts on the first swing arm 11 to drive the second swing arm 12 to move, thereby making the first matching device 13 on the second swing arm 12 contact and link with the second matching device 31, so that the second swing arm 12 drives the pop-up member 3 to switch from the pop-up state to the folded state, and the second component 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 an integrally formed structure, or the first swing arm 11 and the second swing arm 12 are threadedly connected or snap-connected or concave-convexly matched to form a whole, so that when the first swing arm 11 moves, it drives the second swing arm 12 to move synchronously.

[0117] In some embodiments, the first swing arm 11 and the second swing arm 12 form a specific angle, and the angle range can be 10° to 80°, for example, 10°, 20°, 40°, 60° or 80°, etc. The range of the angle is specifically designed according to the pop-up distance of the pop-up member 33 or the distance of relative movement between the first component 100 and the second component 200.

[0118] The rebounding device according to an embodiment of the present invention further includes a mounting plate 20 for being fixed on the first member 100 or the second member 200, and a part of the pressing member 1 is pivotally connected to the mounting plate 20; and / or, the ejecting member 3 is located on the mounting plate 20; and / or, the first elastic member 2 is located on the mounting plate 20; and / or, at least a part of the buffer assembly is located on the mounting plate 20. In this way, the rebounding device 10 can be integrated, so that it is more convenient to mount the rebounding device 10 on the first member 100 or the second member 200 and the structure is more firm and stable. In addition, multiple mounting plates 20 can be provided to surround most of the rebounding device 10, thereby providing a protection effect on the rebounding device 10.

[0119] In some embodiments, at least two adjusting slots 201 are formed on the mounting plate 20. During installation, bolts or the like can be passed through the adjusting slots 201 to lock the mounting plate 20 on the first member 100 or the second member 200. By loosening the bolts and sliding the bolts along the adjusting slots 201, the distance between the rebounding device 10 and the first member 100 or the second member 200 can be adjusted, and the operation is convenient.
