Description

Technical Field

[0001] The present invention relates to a pressing energy storage and rebound mechanism. Background Art

[0002] The patent document number of the applicant is CN211883005U, which discloses an adjustable furniture stable pressing and rebounding structure on November 10, 2020. It includes a moving slide rail and a fixed slide rail that are slidably opened and closed in cooperation with each other. An active member and a pressing action assembly are arranged on the moving slide rail, and a pressing and rebounding device is arranged on the fixed slide rail; the pressing action assembly includes a pressing bracket and an adjusting member. The pressing bracket is fixedly arranged on the moving slide rail, and the adjusting member is adjustably movably arranged on the pressing bracket and presses and rebounds with the pressing and rebounding device; by using a tool or manually acting on the moving slide rail and driving the moving slide rail to slide on the fixed slide rail, when the moving slide rail slides, it automatically slides and opens on the fixed slide rail through the interaction between the adjusting member and the pressing and rebounding device; the mutual pressing and rebounding position between the moving slide rail and the fixed slide rail is adjusted through the adjusting member; when the moving slide rail slides open or closed relative to the fixed slide rail to a certain position, it acts through the active member and drives the pressing and rebounding device to reset to the terminal initial position. Although the above structure can achieve the effect of pressing opening and closing of furniture and the automatic reset of each device when the furniture is opened and closed, however, it is necessary to set multiple components and devices on the furniture product and cooperate with each other through these components and devices, and through the pressing action of the furniture door panel, the above effect can be achieved. Its structure is quite complex and the production cost is quite high. If the assembly position between the components and devices is inaccurate, or displacement and detachment occur during use, the corresponding functions cannot be achieved, affecting the use stability of the furniture product; at the same time, due to the need for the pressing action of the furniture door panel, the entire pressing and rebounding structure needs to extend out of the furniture product to interact with the furniture door panel, which not only occupies the space position of the furniture product but also affects the overall appearance of the furniture product. Therefore, it is necessary to further improve.

[0003] Therefore, it is necessary to make further improvements. Summary of the Invention

[0004] The purpose of the present invention is to provide a pressing energy storage and rebound mechanism to overcome the deficiencies in the prior art.

[0005] A press-storage energy rebound mechanism designed for this purpose includes a rebound device and an assembly element, and is characterized in that: the rebound device includes a bracket element, on which a pressing component, a pushing component and a connecting arm are arranged; the pressing component and the pushing component are arranged independently of each other, and are elastically movable on the bracket element respectively; the connecting arm is hinged to open and close on the bracket element, and a transmission component is arranged on it, and is driven and connected to the pushing component through the transmission component; a disassembly component is arranged between the connecting arm and the assembly element, and the two are disassembled and connected through the disassembly component; when the connecting arm is hinged to open and close relative to the bracket element, it slides on the assembly element through the disassembly component.

[0006] The connecting arm, and / or the assembly element, and / or the disassembly assembly press against each other and drive the pressing assembly and the pushing assembly to lock or unlock each other; when unlocked, the pushing assembly elastically moves on the bracket element and drives the connecting arm to automatically hinge and open to a certain position relative to the bracket element through the transmission assembly.

[0007] The pressing assembly includes a pressing member, on which a pressing elastic portion is provided; the pressing member is provided with a pressing portion in the direction of the connecting arm, and / or the assembly element, and / or the disassembly assembly; the connecting arm, and / or the assembly element, and / or the disassembly assembly and the pressing portion press each other, and drive the pressing member to elastically move on the bracket element through the pressing elastic portion; the pressing member is also provided with a locking portion, and is locked or unlocked with the pushing assembly through the locking portion when elastically moving.

[0008] The pressing portion is arranged at one end of the pressing member, and its end portion at least partially extends out of the bracket element or is located inside the bracket element; the connecting arm, and / or the assembly element, and / or the removal component are provided with a pressing fitting portion in the direction of the pressing portion, and the pressing fitting portion and the pressing portion press each other.

[0009] The pressing member is provided with a position adjustment, and the position adjustment member is adjustably arranged on the pressing member; the pressing part is arranged on the position adjustment member, and is displaced relative to the connecting arm, and / or the assembly element, and / or the dismantling assembly through the adjustment of the position adjustment member, so as to adjust the mutual pressing position between the connecting arm, and / or the assembly element, and / or the dismantling assembly and the pressing part. The pressing elastic part is integrally or separately arranged with the pressing member, one end of which elastically acts on the pressing member, and the other end elastically acts on the bracket element; the pressing part is arranged at one end of the pressing member; the locking part is arranged at the other end of the pressing member; a transfer part is arranged in the middle of the pressing member, and is rotated or swung on the bracket element through the pressing cooperation of the connecting arm, and / or the assembly element, and / or the dismantling assembly with the pressing part.

[0010] The pushing component includes a pushing member and a pushing elastic member; the transmission component includes an opening transmission member and a reset transmission member that are independently arranged.

[0011] A locking and separating cooperation portion is provided on the pushing member, and the pushing member is locked or unlocked with the locking and separating portion through the locking and separating cooperation portion. When unlocked, the pushing member elastically moves on the support element through the pushing elastic member, and when elastically moving, drives the connecting arm to automatically hinge and open a certain position on the support element through the opening transmission member.

[0012] When the connecting arm continues to hinge and open relative to the support element, the pushing member is driven to reset and slide through the reset transmission member. When the pushing member resets and slides to a certain position, it is locked with the locking and separating portion through the locking and separating cooperation portion.

[0013] A hinge portion is provided at the end of the connecting arm, and the connecting arm is hinged to open and close on the support element through the hinge portion; an opening acting portion and a reset connecting portion are respectively provided on both sides of the hinge portion.

[0014] One end of the opening transmission member is hinged to the pushing member, and the other end is driven and connected to the opening acting portion when the connecting arm automatically hinges and opens a certain position, and depends on or separates from the opening acting portion when the connecting arm continues to hinge and open.

[0015] The connecting arm is hinged with an intermediate member through the reset connecting portion, and is in transmission hinge with one end of the reset transmission member in the middle. The other end of the reset transmission member acts and drives the pushing member to reset and slide at least when the connecting arm continues to hinge and open to a certain position.

[0016] A pushing limit groove and an opening limit groove are provided on the support element; a pushing guiding portion and a reset portion are further provided on the pushing member; a pressing guiding portion is further provided on the pressing member.

[0017] When the connecting arm is in the closed state, the pushing member is always locked with the locking and separating portion of the pressing member through the locking and separating cooperation portion. The opening acting portion freely moves on the support element through the drive of the connecting arm and depends on or forms a distance with the opening transmission member. The reset transmission member freely moves on the support element through the drive of the connecting arm and depends on or forms a distance with the reset portion.

[0018] When the connecting arm is in the closed state, an external force drives the connecting arm, and / or the assembling element, and / or the removing and disassembling component to act on the pressing part, and drives the pressing acting part to press against the elastic force of the pressing elastic part, and rotate or swing on the bracket element. When the locking and separating part rotates or swings, it separates from the locking and separating mating part. The pushing acting part elastically linearly limits and slides on the pushing limiting groove through the pushing elastic part when the locking and separating part separates from the locking and separating mating part, and acts on and relies on the pressing guiding part through the pushing guiding part. When the pushing acting part elastically linearly limits and slides, it drives the opening transmission part to limit and slide on the opening limiting groove, and acts on the opening acting part, and drives the connecting arm to automatically hinge and open to a certain position relative to the bracket element. Among them, when the connecting arm opens to a certain position, the reset part and the reset transmission part rely on each other or form a distance.

[0019] When the connecting arm continues to hinge and open relative to the bracket element, the opening acting part separates from the opening transmission part. The connecting arm drives the reset transmission part to linearly slide on the bracket element through the intermediate part. When the reset transmission part linearly slides to a certain position, it acts on the reset part and drives the pushing acting part to reset and slide on the bracket element by overcoming the elastic force of the pushing elastic part. When the pushing acting part resets and slides to a certain position, the pushing guiding part separates from the pressing guiding part. The pressing acting part resets and rotates or swings on the bracket element through the elastic force of the pressing elastic part and is locked with the locking and separating mating part through the locking and separating part.

[0020] When the connecting arm automatically hinges and opens to a certain position relative to the bracket element, an external force drives the connecting arm, and / or the assembling element, and / or the removing and disassembling component to move towards the bracket element, and acts on the opening transmission part through the opening acting part, and drives the pushing acting part to reset and slide on the bracket element by overcoming the elastic force of the pushing elastic part. When the pushing acting part resets and slides to a certain position, the pushing guiding part separates from the pressing guiding part. The pressing acting part resets and rotates or swings on the bracket element through the elastic force of the pressing elastic part and is locked with the locking and separating mating part through the locking and separating part.

[0021] The removing and disassembling component includes a moving part and a disassembling and assembling part. The moving part is arranged on the assembling element, and the disassembling and assembling part is arranged on the connecting arm. A sliding groove part is arranged on the assembling element. The moving part is slidably arranged on the sliding groove part and is provided with a rotating part thereon. An elastic part is arranged between the disassembling and assembling part and the connecting arm. The disassembling and assembling part is elastically arranged on the connecting arm through the elastic part. A buckle part is arranged between the connecting arm and the disassembling and assembling part, and is detachably arranged on the rotating part through the buckle part to realize the detachable rotational sliding connection between the connecting arm and the assembling element.

[0022] Through the improvement of the above structure, the present invention has the following advantages compared with the prior art:

[0023] 1. Integrate the pressing component, the pushing component, the connecting arm, and the transmission component onto the bracket element to simplify the overall structure of the rebounding device, reduce the number of components, and lower the production cost. Since the above components are all integrated onto the bracket element, the connection compactness between components can be improved, which not only facilitates the overall setting of the rebounding device, making it convenient for users' daily use and maintenance, but also enables the working cooperation between components, ensuring that the rebounding device can achieve the effects of automatically hinging and opening the connecting arm to a certain position and automatically resetting the driving component when continuing to open, improving its use stability. At the same time, it can also reduce the volume of the rebounding device, thereby reducing the space occupied during assembly and use.

[0024] 2. Utilize the disassembly, installation, and sliding functions of the dismounting and moving component to enable the connecting arm to be detachably connected to the assembly element and slide on the assembly element when the connecting arm is hinged and opened or closed relative to the bracket element. Furthermore, the entire rebounding device can be applied to the disassembly, installation, opening, and closing cooperation between the furniture door body and the furniture cabinet body, enabling users to conveniently disassemble and install the furniture door body on the furniture cabinet body and hinge and open or close the furniture door body on the furniture cabinet body, greatly facilitating the use of furniture products by users.

[0025] 3. Simply by the mutual pressing action of the connecting arm, and / or the assembly element, and / or the dismounting and moving component with the pressing component, the pushing component can be unlocked, and a opening force can be generated on the connecting arm through the transmission component, driving the connecting arm to automatically hinge and open to a certain position relative to the bracket element, ensuring that users can complete the automatic opening of the connecting arm with the simplest and most convenient operation. At the same time, it also avoids the drawback that the pressing component must be actuated by the furniture door body, reducing the pressing damage to the furniture door body. Moreover, since the connecting arm, and / or the assembly element, and / or the dismounting and moving component act on the pressing component, the rebounding device can be hidden deeper inside the furniture cabinet body during assembly, reducing its exposure or protrusion. Additionally, the pressing component does not need to be set in an extended manner, reducing the risk of accidental touch by users and improving the assembly stability and use safety of the rebounding device.

[0026] 4. When the pushing component is locked, the connecting arm can be freely hinged and opened or closed on the bracket element, facilitating users to directly open and close the connecting arm at any time in addition to the pressing opening operation, and further facilitating the opening and closing of the furniture door body by users.

[0027] 5. When the connecting arm continues to open, it can also reset the pushing component through the transmission component, causing the pushing component to lock with the pressing component again, ensuring that all components can automatically reset when the connecting arm opens, avoiding problems such as the connecting arm being unable to close normally due to inaccurate assembly positions of components or displacement during use, and ensuring the opening and closing stability of the furniture door body.

[0028] 6. When the pushing component is locked, there is no effect between it and the connecting arm. Therefore, the connecting arm can be freely hinged and opened and closed relative to the bracket element, which not only meets more usage requirements of users, but also enables the rebounding device to cooperate with an external hinge to achieve automatic damped closing or automatic closing of the furniture door body, so as to improve the adaptability of the rebounding device.

[0029] 7. When the connecting arm is automatically hinged and opened relative to the bracket element by a certain position, the connecting arm can also be hinged and closed relative to the bracket element again under the action of an external force, and the pushing component can be locked with the pressing component again, so as to further ensure the opening and closing stability and usage safety of the furniture door body.

[0030] Generally speaking, it has the characteristics of simple and reasonable structure, excellent performance, low manufacturing cost, small volume, high connection compactness of each component, simple disassembly and assembly, and safe, convenient, reliable, worry-free, labor-saving and long service life in use, and has strong practicability.

[0043] A position adjusting part 9 is arranged on the pressing element 4, and the position adjusting part 9 is adjustably arranged on the pressing element 4; the pressing part 6 is arranged on the position adjusting part 9, and generates a displacement relative to the connecting arm 3, and / or the assembly element 1, and / or the disassembly and removal component through the adjustment of the position adjusting part 9, so as to adjust the mutual pressing position between the connecting arm 3, and / or the assembly element 1, and / or the disassembly and removal component and the pressing part 6.

[0044] The pressing elastic part 5 is integrally or separately provided with the pressing acting part 4. One end of the pressing elastic part 5 elastically acts on the pressing acting part 4, and the other end elastically acts on the bracket element 2; the pressing part 6 is arranged at one end of the pressing acting part 4; the locking and separating part 7 is arranged at the other end of the pressing acting part 4; a transfer part 10 is arranged in the middle of the pressing acting part 4, and the pressing acting part 4 rotates or swings on the bracket element 2 through the connecting arm 3, and / or the assembling element 1, and / or the removing and moving assembly in pressing cooperation with the pressing part 6.

[0045] The pushing assembly includes a pushing acting part 11 and a pushing elastic part 12; the transmission assembly includes an opening transmission part 13 and a reset transmission part 14 which are independently arranged.

[0046] A locking and separating cooperation part 15 is arranged on the pushing acting part 11, and the pushing acting part 11 is locked or unlocked with the locking and separating part 7 through the locking and separating cooperation part 15.

[0047] When unlocked, the pushing acting part 11 elastically moves on the bracket element 2 through the pushing elastic part 12, and when elastically moving, the pushing acting part 11 drives the connecting arm 3 through the opening transmission part 13 to automatically hinge and open the bracket element 2 to a certain position.

[0048] When the connecting arm 3 continues to hinge and open relative to the bracket element 2, the pushing acting part 11 is driven by the reset transmission part 14 to reset and slide. When the pushing acting part 11 resets and slides to a certain position, the pushing acting part 11 is locked with the locking and separating part 7 through the locking and separating cooperation part 15.

[0049] An articulation part 16 is arranged at the end of the connecting arm 3, and the connecting arm 3 is hinged to open and close on the bracket element 2 through the articulation part 16; an opening acting part 17 and a reset connecting part 18 are respectively arranged on both sides of the articulation part 16.

[0050] One end of the opening transmission part 13 is hinged to the pushing acting part 11, and the other end is driven and connected to the opening acting part 17 when the connecting arm 3 automatically hinges and opens to a certain position, and depends on or separates from the opening acting part 17 when the connecting arm 3 continues to hinge and open.

[0051] The connecting arm 3 is hinged with an intermediate part 19 through the reset connecting part 18. The intermediate part 19 is in transmission hinge connection with one end of the reset transmission part 14. The other end of the reset transmission part 14 acts on and drives the pushing acting part 11 to reset and slide at least when the connecting arm 3 continues to hinge and open to a certain position.

[0052] A pushing limiting groove 20 and an opening limiting groove 21 are arranged on the bracket element 2; a pushing guiding part 22 and a reset part 23 are further arranged on the pushing acting part 11; a pressing guiding part 24 is further arranged on the pressing acting part 4.

[0053] When the connecting arm 3 is in the closed state, the pushing member 11 is always locked with the locking and separating portion 7 of the pressing member 4 through the locking and separating engaging portion 15. The opening portion 17 is driven by the connecting arm 3 to move freely on the bracket element 2 and depends on or forms a distance from the opening transmission member 13. The reset transmission member 14 is driven by the connecting arm 3 to move freely on the bracket element 2 and depends on or forms a distance from the reset portion 23.

[0054] When the connecting arm 3 is in the closed state, an external force is used to drive the connecting arm 3, and / or the assembly element 1, and / or the dismounting assembly to act on the pressing portion 6, and drive the pressing member 4 to press against the elastic force of the pressing elastic portion 5 and rotate or swing on the bracket element 2. The locking and separating portion 7 separates from the locking and separating engaging portion 15 when the pressing member 4 rotates or swings. The pushing member 11 elastically linearly limits and slides on the pushing limiting groove 20 through the pushing elastic member 12 when the locking and separating portion 7 separates from the locking and separating engaging portion 15, and acts on and depends on the pressing guiding portion 24 through the pushing guiding portion 22. The pushing member 11 drives the opening transmission member 13 to limit and slide on the opening limiting groove 21 and act on the opening portion 17 when elastically linearly limiting and sliding, and drives the connecting arm 3 to automatically hinge and open by a certain position relative to the bracket element 2. Wherein, the reset portion 23 depends on or forms a distance from the reset transmission member 14 when the connecting arm 3 opens by a certain position.

[0055] When the connecting arm 3 continues to hinge and open relative to the bracket element 2, the opening portion 17 separates from the opening transmission member 13. The connecting arm 3 drives the reset transmission member 14 to linearly slide on the bracket element 2 through the intermediate member 19. The reset transmission member 14 acts on the reset portion 23 when linearly sliding to a certain position and drives the pushing member 11 to reset and slide on the bracket element 2 by overcoming the elastic force of the pushing elastic member 12. When the pushing member 11 resets and slides to a certain position, the pushing guiding portion 22 separates from the pressing guiding portion 24. The pressing member 4 resets and rotates or swings on the bracket element 2 by the elastic force of the pressing elastic portion 5 and is locked with the locking and separating engaging portion 15 through the locking and separating portion 7.

[0056] Its working principle is as follows:

[0057] See Figures 6 - 10, the connecting arm 3 is in the closed state. By applying an external force to drive the connecting arm 3, and / or the assembly element 1, and / or the removal and installation component, the pressing and fitting part 8 acts on the pressing part 6, so that the pressing acting part 4 presses and overcomes the elastic force of the pressing elastic part 5 to rotate or swing on the bracket element 2. The locking and separating part 7 separates from the locking and separating fitting part 15 when the pressing acting part 4 rotates or swings. At this time, the pushing acting part 11 elastically linearly limits and slides on the pushing limit groove 20 (to the right) through the pushing elastic part 12, and acts on and relies on the pressing guiding part 24 through the pushing guiding part 22. At the same time, when the pushing acting part 11 elastically linearly limits and slides, it drives the opening transmission part 13 to limit and slide on the opening limit groove 21 (tilted to the right) and acts on the opening acting part 17, and drives the connecting arm 3 to automatically hinge and open to a certain position relative to the bracket element 2. Among them, the opening transmission part 13 and the reset transmission part 14 are respectively located on both sides of the hinge part 16 of the connecting arm 3. Therefore, when the connecting arm 3 automatically hinges and opens, the reset transmission part 14 will slide in the opposite direction relative to the opening transmission part 13 (that is, the reset transmission part 14 slides to the left on the bracket element 2). At this time, the reset part 23 relies on each other or forms a distance from the reset transmission part 14 when the connecting arm 3 opens to a certain position.

[0058] When the connecting arm 3 continues to hinge and open relative to the bracket element 2 (by applying an external force), the opening acting part 17 separates from the opening transmission part 13. The connecting arm 3 drives the reset transmission part 14 to linearly slide on the bracket element 2 (to the left) through the intermediate part 19. When the reset transmission part 14 linearly slides, it acts on the reset part 23 and drives the pushing acting part 11 to reset and slide on the bracket element 2 (to the left) by overcoming the elastic force of the pushing elastic part 12. When the pushing acting part 11 resets and slides to a certain position, the pushing guiding part 22 separates from the pressing guiding part 24. The pressing acting part 4 resets and rotates or swings on the bracket element 2 through the elastic force of the pressing elastic part 5 and is locked with the locking and separating fitting part 15 through the locking and separating part 7. At this time, the pushing acting part 11 will be positioned on the bracket element 2, and at the same time, a distance is also formed between the opening transmission part 13 and the opening acting part 17.

[0059] Since the pushing acting part 11 is in the locked state and there is no acting relationship between it and the connecting arm 3 and the reset transmission part 14, the connecting arm 3 can freely hinge and open and close relative to the bracket element 2.

[0060] When the connecting arm 3 is automatically hinged and opened relative to the support element 2 by a certain position, the connecting arm 3, and / or the assembling element 1, and / or the removing and installing assembly are driven by an external force to move in the direction of the support element 2, and act on the opening transmission member 13 through the opening acting portion 17, and drive the pushing acting member 11 to overcome the elastic force of the pushing elastic member 12 and reset and slide on the support element 2; when the pushing acting member 11 is reset and slides to a certain position, the pushing guiding portion 22 is separated from the pressing guiding portion 24, and the pressing acting member 4 is reset and rotated or swung on the support element 2 by the elastic force of the pressing elastic portion 5, and is locked with the unlocking and engaging portion 15 through the unlocking portion 7.

[0061] Its working principle is as follows:

[0062] See Figures 11 - 13 , when the connecting arm 3 is automatically hinged and opened relative to the support element 2 by a certain position, the connecting arm 3, and / or the assembling element 1, and / or the removing and installing assembly are driven by an external force to move in the direction of the support element 21 (i.e., the connecting arm 3 is re-hinged and closed), so that the pressing cooperation portion 8 acts on the pressing portion 6, and the pressing acting member 4 presses and overcomes the elastic force of the pressing elastic portion 5 and rotates or swings on the support element 2. At the same time, the connecting arm 3 acts on the opening transmission member 13 through the opening acting portion 17, and drives the pushing acting member 11 to overcome the elastic force of the pushing elastic member 12 and reset and slide on the support element 2 (to the left); when the pushing acting member 11 is reset and slides to a certain position, the pushing guiding portion 22 is separated from the pressing guiding portion 24. At this time, the external force disappears, and the pressing acting member 4 is reset and rotated or swung on the support element 2 by the elastic force of the pressing elastic portion 5, and is locked with the unlocking and engaging portion 15 through the unlocking portion 7, so that the pressing acting member 4 and the pushing acting member 11 are re-locked.

[0063] The removing and installing assembly includes a moving member 29 and a disassembling and installing member 30; the moving member 29 is arranged on the assembling element 1, and the disassembling and installing member 30 is arranged on the connecting arm 3; a sliding groove portion 25 is arranged on the assembling element 1; the moving member 29 is slidably arranged on the sliding groove portion 25, and a rotating portion 26 is arranged thereon; an elastic member 27 is arranged between the disassembling and installing member 30 and the connecting arm 3; the disassembling and installing member 30 is elastically arranged on the connecting arm 3 through the elastic member 27; a buckle portion 28 is arranged between the connecting arm 3 and the disassembling and installing member 30, and is detachably arranged on the rotating portion 26 through the buckle portion 28 to realize the detachable and rotatable sliding connection between the connecting arm 3 and the assembling element 1.
