[0014] The locking member is locked with the action shaft through the cooperation of the locking portion and the locking elastic member at least when the connecting arm is in the closed state.

[0015] When the locking member moves elastically, the arc-shaped locking position and the arc-shaped acting position of the acting shaft are mutually locked or unlocked in an arc form.

[0016] The locking member is also provided with a positioning portion; the action shaft is separated from the locking portion at least when the connecting arm is in the open state, and acts on the positioning portion, so that the locking member overcomes the elastic force of the locking elastic member and is positioned on the bracket.

[0017] The pressing assembly also includes a pressing piece and an intermediate piece; a pressing elastic piece is arranged between the pressing piece and the bracket, one end of the pressing elastic piece is elastically positioned on the pressing piece, and the other end is elastically positioned on the bracket; the pressing piece slides on the bracket through the pressing elastic piece's pressing elastic telescopic movement; the intermediate piece rotates or swings on the bracket, and its two ends are respectively hinged to the pressing piece and the locking piece for mutual transmission.

[0018] The pressing piece is pressed and moved when the connecting arm is in a closed state, and drives the locking piece through the intermediate piece to overcome the elastic force of the locking elastic piece and slide on the bracket. When the locking piece slides, the locking part unlocks each other in an arc form through the arc-shaped locking position and the arc-shaped action position, so as to realize the automatic hinged opening of the connecting arm relative to the bracket to a certain position or fully open to the terminal position.

[0019] The pushing component further includes a pushing elastic member; a pushing acting portion is provided on the pushing acting member; one end of the pushing elastic member is elastically positioned and acts on the pushing acting member, and the other end is elastically positioned and acts on the bracket; when unlocked, the pushing acting member elastically linearly slides on the bracket through the pushing elastic member, and when elastically linearly sliding, acts on the pushing transmission member through the pushing acting portion, and drives the connecting arm to automatically hinge and open a certain position or fully open to the terminal position relative to the bracket.

[0020] The opening and closing component includes an opening and closing acting member and an opening and closing elastic member; the opening and closing acting member is cooperatively connected with the opening and closing transmission member; one end of the opening and closing elastic member is elastically positioned and acts on the opening and closing acting member, and the other end is elastically positioned and acts on the bracket; when the connecting arm hinges and opens or closes relative to the bracket, the opening and closing acting member elastically linearly slides on the bracket through the opening and closing elastic member, and when elastically linearly sliding, applies an opening and closing acting force to the connecting arm through the opening and closing transmission member.

[0021] The reset component includes a pushing reset member and an opening and closing reset member.

[0022] A pushing reset elastic member is provided between the pushing reset member and the pushing acting member. One end of the pushing reset elastic member elastically acts on the pushing reset member, and the other end elastically acts on the pushing acting member; the pushing reset member elastically moves on the pushing acting member through the pushing reset elastic member.

[0023] An opening and closing reset elastic member is provided between the opening and closing reset member and the opening and closing acting member. One end of the opening and closing reset elastic member is elastically positioned and acts on the opening and closing reset member, and the other end is elastically positioned and acts on the opening and closing acting member; the opening and closing reset member elastically moves on the opening and closing acting member through the opening and closing reset elastic member.

[0025] A guiding portion is provided on the bracket.

[0026] When the connecting arm automatically hinges and opens a certain position relative to the bracket, the pushing reset member acts on and relies on the guiding portion, and interacts with the opening and closing reset member. When the connecting arm continues to hinge and open relative to the bracket, the opening and closing acting member slides in the direction of the pushing acting member, and drives the pushing acting member to reset and slide on the bracket through the cooperation of the opening and closing reset member and the pushing reset member. When the pushing acting member resets and slides to a certain position, it is arc-shaped and locked with the unlocking member through the arc-shaped cooperation portion; wherein, when the connecting arm hinges and closes relative to the bracket, the opening and closing reset member and the pushing reset member are separated from each other, and the connecting arm freely hinges and closes relative to the bracket.

[0027] Alternatively, the pushing and resetting member acts and relies on the guiding portion when the connecting arm is fully opened relative to the bracket to the terminal position, and interacts with the opening and closing resetting member. When the connecting arm is hinged and closed relative to the bracket, the opening and closing acting member slides in the direction of the pushing acting member, and drives the pushing acting member to reset and slide on the bracket through the cooperation of the opening and closing resetting member and the pushing and resetting member. When the pushing acting member resets and slides to a certain position, it is arc-shaped and locked with the unlocking member through the arc-shaped matching portion.

[0028] The bracket is respectively provided with a first linear groove portion, a second linear groove portion and an arc groove portion.

[0029] One end of the pushing transmission member slides on the first linear groove portion, and a first shaft portion is provided between the other end and the connecting arm, and the two are hinged through the first shaft portion.

[0030] A second shaft portion (28) is provided between one end of the opening and closing transmission member and the connecting arm, and the two are hinged and slide on the arc groove portion through the second shaft portion. A third shaft portion is provided between the other end of the opening and closing transmission member and the opening and closing acting member, and the two are hinged and slide on the second linear groove portion through the third shaft portion.

[0031] When the connecting arm is hinged and opened relative to the bracket, and the included angle a between the first, second and third shaft portions is less than 180 degrees, the opening and closing acting member elastically moves on the bracket through the opening and closing elastic member, and applies an opening acting force to the connecting arm through the opening and closing transmission member during the elastic movement.

[0032] When the connecting arm is hinged and closed relative to the bracket, and the included angle a between the first, second and third shaft portions is greater than 180 degrees, the opening and closing acting member elastically moves on the bracket through the opening and closing elastic member, and applies a closing acting force to the connecting arm through the opening and closing transmission member during the elastic movement.

[0033] Through the improvement of the above structure, the present invention has the following advantages compared with the prior art:

[0034] 1. The pressing assembly, the pushing assembly, the opening and closing assembly, the connecting arm and the reset assembly are arranged on the bracket to simplify the overall structure of the pressing and opening and closing device, reduce the number of components, and reduce the production cost; since the above components are all arranged on the bracket, the connection compactness between the components can be improved, which is not only beneficial to the overall setting of the pressing and opening and closing device, convenient for the daily use and maintenance of users, but also convenient for the working cooperation between the components, ensuring that the pressing and opening and closing device can achieve the effect of automatic pressing, opening and closing and resetting, improving its use stability, and at the same time reducing the volume of the pressing and opening and closing device, thereby reducing the space position occupied during assembly and use.

[0035] 2. By interlocking or unlocking between the pressing component and the pushing component, the connecting arm can be stably closed on the bracket. Among them, when unlocked, the pushing component can drive the connecting arm to be hingedly opened through the pushing transmission part. When the connecting arm is hingedly opened, the hinged angle between the pushing transmission part and the opening / closing transmission part changes, so that the connecting arm can be automatically hingedly opened to a certain position or fully opened to the terminal position relative to the bracket, ensuring that the user can complete the automatic opening of the connecting arm with the simplest, convenient and fast operation.

[0036] 3. When the connecting arm is opened or closed, it can reset the pushing component through the cooperation of the opening / closing component and the reset component, so that the pushing component is locked with the pressing component again, ensuring that each component can be automatically reset when opened or closed, so as to avoid the problem that the connecting arm cannot be normally opened or closed due to non-standard assembly positions of each component or detachment during use.

[0037] 4. By using the arc matching effect of the arc matching part, the pushing acting part and the locking / unlocking part can achieve arc-shaped interlocking or unlocking with each other, which not only reduces the friction between the two, improves the service life, but also improves the position conversion speed and rationality when the two are locked or unlocked, allowing the locking / unlocking part to only slide a small position to lock or unlock with the locking / unlocking part, enabling the pushing acting part and the locking / unlocking part to achieve rapid locking or unlocking, and improving the user's convenience of use.

[0038] 5. The opening / closing acting part can apply an opening or closing force to the connecting arm through the opening / closing elastic part, so that when the connecting arm is hingedly opened or closed relative to the bracket to a certain position, it can freely achieve automatic opening or automatic closing, so as to improve the convenience of use of the pressing opening / closing device.

[0039] Generally speaking, it has the characteristics of simple and reasonable structure, excellent performance, low manufacturing cost, small volume, high connection compactness of each component, and safe, convenient, reliable, worry-free and labor-saving for users, and has strong practicability.

[0072] A guiding portion 23 is provided on the bracket 1.

[0073] When the pushing and resetting member 19 acts and relies on the guiding portion 23 when the connecting arm 2 is automatically hinged and opened by a certain position relative to the bracket 1, and interacts with the opening and closing resetting member 20, the opening and closing acting member 17 slides in the direction of the pushing acting member 6 when the connecting arm 2 continues to be hinged and opened relative to the bracket 1, and drives the pushing acting member 6 to reset and slide on the bracket 1 through the cooperation of the opening and closing resetting member 20 and the pushing and resetting member 19; when the pushing acting member 6 resets and slides to a certain position, it is arc-shaped and locked with the unlocking member 5 through the arc-shaped cooperation portion; wherein, when the connecting arm 2 is hinged and closed relative to the bracket 1, the opening and closing resetting member 20 and the pushing and resetting member 19 are separated from each other, and the connecting arm 2 is freely hinged and closed relative to the bracket 1.

[0074] Specifically, a reset portion 31 and a guiding and cooperating portion 32 are provided on the pushing and resetting member 19; a reset cooperating portion 33 and an opening and closing guiding portion 34 are provided on the opening and closing resetting member 20.

[0075] A first linear groove portion 24, a second linear groove portion 25 and an arc groove portion 26 are respectively provided on the bracket 1.

[0076] One end of the pushing transmission member 3 slides on the first linear groove portion 24, and a first shaft portion 27 is provided between the other end and the connecting arm 2, and the two are hinged through the first shaft portion 27.

[0077] One end of the opening and closing transmission member 4 is provided with a second shaft portion 28 between it and the connecting arm 2, and the two are hinged and slide on the arc groove portion 26 through the second shaft portion 28. A third shaft portion 29 is provided between the other end of the opening and closing transmission member 4 and the opening and closing acting member 17, and the two are hinged and slide on the second linear groove portion 25 through the third shaft portion 29.

[0078] The above-mentioned first linear groove portion 24, second linear groove portion 25 and arc groove portion 26 only have the functions of avoidance and guiding, and can make the activities between the pushing transmission member 3, the opening and closing transmission member 4 and the connecting arm 2 more stable. And the first linear groove portion 24, the second linear groove portion 25 and the arc groove portion 26 can also not be provided according to the production and assembly conditions.

[0079] When the connecting arm 2 is hinged and opened relative to the bracket 1, and the included angle a between the first, second and third shaft portions is less than 180 degrees, the opening and closing acting member 17 elastically moves on the bracket 1 through the opening and closing elastic member 18, and applies an opening acting force to the connecting arm 2 through the opening and closing transmission member 4 during the elastic movement.

[0080] When the connecting arm 2 is hinged and closed relative to the bracket 1, and the included angle a between the first, second and third shaft portions is greater than 180 degrees, the opening and closing acting member 17 elastically moves on the bracket 1 through the opening and closing elastic member 18, and applies a closing acting force to the connecting arm 2 through the opening and closing transmission member 4 during the elastic movement.

[0081] Such as Figures 7 - 11As shown, press the pressing member 13 to slide it in the direction of the bracket 1 against the elastic force of the pressing elastic member 30, and drive the intermediate member 14 to rotate or swing on the bracket 1. When the intermediate member 14 rotates or swings, it drives the locking and separating member 5 to slide on the bracket 1 against the elastic force of the locking and separating elastic member 9. At this time, the arc acting position 8 and the locking and separating portion 11 are separated from each other. At the same time, the locking and separating member 5 and the pushing acting member 6 are unlocked from each other, and the pushing acting member 6 elastically linearly slides on the bracket 1 (to the right) through the pushing elastic member 15, and drives the connecting arm 2 to automatically hinge open to a certain position.

[0082] Among them, when the pushing acting member 6 elastically linearly slides to a certain position, it acts through the guiding and fitting portion 32 and relies on the guiding portion 23, and drives the pushing and resetting member 19 to move on the pushing acting member 6 against the elastic force of the pushing and resetting elastic member 21. At the same time, the resetting and fitting portion 33 also relies on the resetting portion 31.

[0083] Act on the connecting arm 2 by means of a tool or manually, and drive the connecting arm 2 to continue to hinge open relative to the bracket 1. When the connecting arm 2 continues to hinge open on 1, it drives the opening and closing acting member 17 to move on the bracket 1 (to the left) against the elastic force of the opening and closing elastic member 18 through the opening and closing transmission member 4, and the opening and closing elastic member 18 compresses and stores energy; when the opening and closing acting member 17 moves to a certain position, it acts on the resetting portion 31 through the resetting and fitting portion 33, and drives the pushing acting member 6 to reset and slide (to the left) against the elastic force of the pushing elastic member 15. When the pushing acting member 6 resets and slides to a certain position, it is arc-shaped and locked with the locking and separating member 5 through the arc-shaped fitting portion. At this time, the guiding and fitting portion 32 is separated from the guiding portion 23, the resetting and fitting portion 33 is separated from the resetting portion 31, and the pushing and resetting member 19 is reset to the initial position through the pushing and resetting elastic member 21.

[0084] When the connecting arm 2 continues to open and the angle a between the first, second, and third shaft portions is less than 180 degrees, the opening and closing acting member 17 realizes a steering action. The opening and closing acting member 17 elastically moves on the bracket 1 (to the right) through the opening and closing elastic member 18, and applies an opening force to the connecting arm 2 through the opening and closing transmission member 4, so that the connecting arm 2 is completely hinged open to the terminal position and is positioned on the bracket 1.

[0085] When the connecting arm 2 is in the open state, a gap is formed between the pushing transmission member 3 and the pushing acting portion 16.

[0086] Apply a closing force to the connecting arm 2. The connecting arm 2 is hinged and closed on the bracket 1, and drives the opening and closing acting member 17 to move on the bracket 1 (to the left) against the elastic force of the opening and closing elastic member 18 through the opening and closing transmission member 4, and the opening and closing elastic member 18 compresses and stores energy. Since the pushing assembly is in the locked state, and at the same time the opening and closing resetting member 20 and the pushing and resetting member 19 are in a state of being separated from each other and not in contact, the connecting arm 2 can be freely hinged and closed relative to the bracket 1.

[0087] When the included angle a between the first, second, and third shaft parts is greater than 180 degrees, the opening and closing acting part 17 realizes the steering function. The opening and closing acting part 17 elastically moves on the bracket 1 (to the right) through the opening and closing elastic part 18, and applies a closing acting force to the connecting arm 2 through the opening and closing transmission part 4. The connecting arm 2 realizes completely automatic articulated closing through the elastic sliding of the pushing acting part 6 and is positioned on the bracket 1.

[0088] Among them, the above-mentioned pressing opening and closing device can be applied to furniture equipment, where the furniture equipment includes a cabinet body X, a door body Y, and a hinge 40. The bracket 1 is fixedly arranged on the cabinet body. A sliding part Z is arranged on the door body Y. The outer end of the connecting arm 2 is detachably slid on the sliding part Z. The hinge 40 is respectively hinged and matched with the cabinet body X and the door body Y. The door body Y can be automatically articulated and opened and closed in a pressing manner on the cabinet body X by the cooperation of the pressing opening and closing device, the sliding part Z, and the hinge 40.

[0089] At the same time, in order to enable the door body Y to realize damped closing, the hinge 40 is a damped hinge 40, and the door body Y is damped and closed on the cabinet body X through the damped hinge 40 when closing. Embodiment

[0090] See Figures 12 - 16 , this automatic reset pressing opening and closing device is different from the first embodiment in that: a reset component is arranged between the pushing component and the opening and closing component, and the two are reset and cooperated through the reset component when the connecting arm 2 is articulated and closed.

[0091] The pressing part 13 presses and moves when the connecting arm 2 is in the closed state, and drives the locking and separating part 5 to slide on the bracket 1 by overcoming the elastic force of the locking and separating elastic part 9 through the intermediate part 14. When the locking and separating part 5 slides, the locking and separating part 11 is arc-shaped and unlocked from the arc-shaped acting position 8 through the arc-shaped locking and separating position 7, so as to realize the automatic complete articulated opening of the connecting arm 2 relative to the bracket 1 to the terminal position.

[0092] When unlocking, the pushing acting part 6 elastically linearly slides on the bracket 1 through the pushing elastic part 15, and when elastically linearly sliding, acts on the pushing transmission part 3 through the pushing acting part 16, and drives the connecting arm 2 to automatically completely articulate and open relative to the bracket 1 to the terminal position.

[0093] The pushing reset part 19 acts and relies on the guiding part 23 when the connecting arm 2 is completely opened relative to the bracket 1 to the terminal position, and interacts with the opening and closing reset part 20. When the connecting arm 2 is articulated and closed relative to the bracket 1, the opening and closing acting part 17 slides in the direction of the pushing acting part 6, and drives the pushing acting part 6 to reset and slide on the bracket 1 through the cooperation of the opening and closing reset part 20 and the pushing reset part 19. When the pushing acting part 6 resets and slides to a certain position, it is arc-shaped and locked with the locking and separating part 5 through the arc-shaped matching part.

[0094] Specifically, asFigures 14 - 16 As shown, press the pressing member 13 so that it slides in the direction of the bracket 1 against the elastic force of the pressing elastic member 30, and drive the intermediate member 14 to rotate or swing on the bracket 1. When the intermediate member 14 rotates or swings, it drives the locking and separating member 5 to slide on the bracket 1 against the elastic force of the locking and separating elastic member 9. At this time, the arc acting position 8 and the locking and separating portion 11 are separated from each other, and at the same time, the locking and separating member 5 and the pushing acting member 6 are unlocked from each other. The pushing acting member 6 then elastically linearly slides on the bracket 1 (to the right) through the pushing elastic member 15, and drives the connecting arm 2 to be automatically hinged and opened; wherein, when the pushing acting member 6 elastically linearly slides to a certain position, it acts through the guiding and fitting portion 32 and relies on the guiding portion 23, and drives the pushing reset member 19 to move on the pushing acting member 6 against the elastic force of the pushing reset elastic member 21.

[0095] The elastic acting force generated by the pushing elastic member 15 is greater than the elastic acting force generated by the opening and closing elastic member 18. Therefore, when the pushing acting member 6 unlocks and slides, it slides to the right on the bracket 1. The opening and closing acting member 17 linearly slides in the opposite direction (to the left) relative to the pushing acting member 6 due to the turning action of the connecting arm 2 and the opening and closing transmission member 4, and the opening and closing elastic member 18 is compressed and stores energy.

[0096] When the connecting arm 2 continues to be automatically opened due to inertia and the included angle a between the first, second, and third shaft portions is less than 180 degrees, the opening and closing acting member 17 realizes the turning action. The opening and closing acting member 17 elastically moves on the bracket 1 (to the right) through the opening and closing elastic member 18, and applies an opening acting force to the connecting arm 2 through the opening and closing transmission member 4. At this time, the pushing reset member 19 and the opening and closing guiding portion 34 interact with each other, and drive the opening and closing reset member 20 to move on the opening and closing acting member 17 against the elastic force of the opening and closing reset elastic member 22 and avoid each other with the pushing reset member 19; when the opening and closing acting member 17 continues to elastically move, the opening and closing guiding portion 34 and the pushing reset member 19 are separated from each other. When the opening and closing guiding portion 34 and the pushing reset member 19 are separated, the opening and closing reset member 20 is reset to the initial position through the opening and closing reset elastic member 22. The connecting arm 2 is then automatically fully hinged and opened to the terminal position through the elastic sliding of the pushing acting member 6 and is positioned on the bracket 1.

[0097] A closing force is applied to the connecting arm 2. The connecting arm 2 is hinged and closed on the bracket 1, and drives the opening and closing acting member 17 through the opening and closing transmission member 4 to move (to the left) on the bracket 1 against the elastic force of the opening and closing elastic member 18, and the opening and closing elastic member 18 is compressed to store energy. When the opening and closing acting member 17 moves to a certain position, it acts on the reset portion 31 through the reset mating portion 33, and drives the pushing acting member 6 to reset and slide (to the left) against the elastic force of the pushing elastic member 15. When the pushing acting member 6 resets and slides to a certain position, it is arc-shaped and locked with the unlocking member 5 through the arc-shaped mating portion. At this time, the guiding mating portion 32 is separated from the guiding portion 23, the reset mating portion 33 is separated from the reset portion 31, and the pushing reset member 19 resets to the initial position through the pushing reset elastic member 21.

[0098] When the included angle a between the first, second, and third shaft portions is greater than 180 degrees, the opening and closing acting member 17 realizes a steering function. The opening and closing acting member 17 elastically moves (to the right) on the bracket 1 through the opening and closing elastic member 18, and applies a closing acting force to the connecting arm 2 through the opening and closing transmission member 4. The connecting arm 2 realizes completely automatic hinged closing through the elastic sliding of the pushing acting member 6 and is positioned on the bracket 1.

[0099] In order to enable the connecting arm 2 to achieve a damped hinged opening effect, an opening damper 35 is further provided on the bracket 1 or the opening and closing acting member 17 of the opening and closing assembly. The opening damper 35 is an automatic reset damper or a non-automatic reset damper and is positioned on the bracket 1 or the opening and closing acting member 17. When the connecting arm 2 is hinged and opened relative to the bracket 1 to a certain position, the opening and closing acting member 17 acts on the opening damper 35, and the opening damper 35 is compressed and generates an opening damping force to realize the automatic complete damped hinged opening of the connecting arm 2 relative to the bracket 1 to the terminal position.

[0100] In order to enable the connecting arm 2 to achieve a damped hinged closing effect, a closing damper 36 is further provided on the bracket 1 or the pushing acting member 6 of the pushing assembly. The closing damper 36 is an automatic reset damper or a non-automatic reset damper and is positioned on the bracket 1 or the pushing acting member 6. When the connecting arm 2 is hinged and closed relative to the bracket 1 to a certain position, the pushing transmission member 3 of the transmission assembly acts on the closing damper 36, and the closing damper 36 is compressed and generates a closing damping force to realize the automatic damped hinged closing of the connecting arm 2 relative to the bracket 1.
