Description

Technical Field

[0001] The invention relates to a stable opening and closing structure of a press-rebound device. Background Art

[0002] Chinese patent document No. CN110786658A disclosed on November 8, 2019 an adjustable furniture stable press-rebound structure, including a movable slide rail and a fixed slide rail that slide and open and close with each other, the movable slide rail is provided with a movable part and a press-action component, and the fixed slide rail is provided with a press-rebound device; the press-action component includes a press bracket and an adjusting part, the press bracket is fixedly arranged on the movable slide rail, and the adjusting part is adjustably and movably arranged on the press bracket, and has a press-rebound effect on each other with the press-rebound device; the movable slide rail is acted on by a tool or manually, and the movable slide rail is driven to slide on the fixed slide rail, and the movable slide rail automatically slides and opens on the fixed slide rail through the interaction between the adjusting part and the press-rebound device when sliding; the mutual press-rebound action position between the movable slide rail and the fixed slide rail is adjusted by the adjusting part; when the movable slide rail slides open or closes to a certain position relative to the fixed slide rail, the movable part acts and drives the press-rebound device to reset to the terminal initial position.

[0003] When the above structure is pressed to open, the elasticity of the pressing elastic member must be overcome so that the push member can slide open along the track of the heart-shaped slide groove. Due to the large elasticity of the pressing elastic member, the user needs to apply the same force when pressing, which results in the user having to use a large force to press open the furniture. At the same time, due to the low compactness of the connection between the components in the pressing rebound device, there will always be collisions between the components when opening or closing, resulting in various abnormal noises during the opening and closing process of the furniture, reducing the service life of the product. In addition, the assembly positions of the movable rail and the fixed rail are fixed when leaving the factory. When the pressing rebound device and the movable part are respectively fixed on the movable rail and the fixed rail, the assembly requirements are high. If the assembly positions of the pressing rebound device and the movable part on the movable rail and the fixed rail are too forward or too backward, then there will be problems with the effective action position between the pressing rebound device and the movable part, resulting in the inability of the two to function normally, or to be separated normally after functioning, resulting in the inability of the movable rail and the fixed rail to be pressed open and closed normally, affecting the user experience. Further improvements are necessary. Summary of the invention

The rebound bracket is provided with a heart-shaped slide groove, and the pushing element is provided with a sliding shaft portion. The sliding element elastically telescopes and limits the sliding on the pushing element and / or the rebound bracket, and acts and drives the sliding shaft portion to position and / or slide along the trajectory of the heart-shaped slide groove in a sequential direction during sliding. It is characterized in that: the sliding element is provided with a heart-groove sliding guide portion and an auxiliary part, the auxiliary part elastically positions and slides on the sliding element, and is provided with a heart-groove sliding buffer portion and a temporary portion.

When the sliding shaft part slides to a certain position, it is disengaged from the core groove sliding into the guide part, and relies on and acts on the core groove sliding into the buffer part and / or the inclined guide part. The sliding shaft part is guided by the core groove sliding into the buffer part and / or the inclined guide part to slide in and be temporarily positioned on the temporary part and the pause area; wherein, the sliding element elastically slides with the auxiliary part when the sliding shaft part and the core groove sliding into the guide part are disengaged.

[0011] When the sliding shaft portion is temporarily positioned on the temporary portion and the pause area, and the sliding element and the auxiliary part elastically reset and slide relative to each other, the sliding shaft portion is separated from the temporary portion and the pause area, and is guided to slide on the inclined guide portion and stay in the heart-shaped stay area; wherein the pushing element and / or the sliding element is positioned in the rebound bracket when the sliding shaft portion stays in the heart-shaped stay area.

[0012] The auxiliary part is provided with a positioning portion, the sliding element is provided with a positioning matching portion, and an auxiliary elastic part is also provided between the auxiliary part and the sliding element. One end of the auxiliary elastic part is elastically connected to the auxiliary part, and the other end is elastically connected to the sliding element. The auxiliary part is elastically positioned and slid on the positioning matching portion of the sliding element in the sliding direction of the sliding element through the cooperation of the positioning portion and the auxiliary elastic part.

[0013] A limiting portion is provided on the sliding element, a limiting matching portion is provided on the pushing element, and a sliding elastic member is also provided between the sliding element and the pushing element, one end of the sliding elastic member is elastically connected to the sliding element, and the other end is elastically connected to the pushing element; the sliding element always slides in the opposite direction toward the sliding element through the cooperation of the limiting portion and the sliding elastic member, and elastically telescopes and limits the sliding on the limiting matching portion of the pushing element.

[0014] A pressing elastic part is arranged between the pushing element and the rebound bracket, one end of the pressing elastic part is elastically connected to the pushing element, and the other end is elastically connected to the rebound bracket; when the sliding shaft portion stays in the heart-shaped staying area and the sliding element presses and slides relative to the rebound bracket, the sliding element and / or the auxiliary part acts and drives the sliding shaft portion to slide out of the heart-shaped staying area, and the pushing element and / or the sliding element slides out of the rebound bracket through the pressing elastic part when the sliding shaft portion slides out of the heart-shaped staying area.

[0015] The elastic force generated by the pressing elastic part is greater than the elastic force generated by the sliding elastic part and / or the auxiliary elastic part; the elastic force generated by the auxiliary elastic part is greater than the elastic force generated by the sliding elastic part; the force of the sliding shaft part guiding the sliding on the inclined guide part is greater than the elastic force generated by the sliding elastic part.

[0016] The sliding element and / or the auxiliary component is provided with a core groove sliding out guide portion.

[0017] When the sliding shaft portion stays in the heart-shaped staying area and the sliding element is pressed and slid relative to the rebound bracket, the sliding element and / or the auxiliary part slides out of the heart groove guide portion and drives the sliding shaft portion to slide out of the heart-shaped staying area, and the pushing element and / or the sliding element slides out of the rebound bracket by pressing the elastic part when the sliding shaft portion slides out of the heart-shaped staying area.

[0018] The heart-shaped slide is also provided with an upper limit sliding area and a conversion area; the upper limit sliding area, the conversion area, the lower limit sliding area, the pause area, and the heart-shaped stay area are connected end to end to form a heart-shaped slide.

[0019] When the sliding element slides into the rebound bracket, it is acted on by the core groove sliding guide part and drives the sliding shaft part to slide on the lower limit sliding area. When the sliding shaft part slides to a certain position, it is disengaged from the core groove sliding guide part, and relies on and acts on the core groove sliding buffer part and the inclined guide part. The sliding shaft part is guided by the core groove sliding buffer part and the inclined guide part to slide in and be temporarily positioned on the temporary part and the pause area; wherein, the sliding element elastically slides with the auxiliary part when the sliding shaft part and the core groove sliding guide part are disengaged.

[0020] The sliding shaft portion is temporarily positioned on the temporary portion and the pause area, and when the sliding element slides elastically with the auxiliary member through the auxiliary elastic member, the sliding shaft portion is separated from the temporary portion and the pause area, and is guided to slide on the inclined guide portion and stay in the heart-shaped stay area; wherein the pushing element and / or the sliding element is positioned in the rebound bracket when the sliding shaft portion stays in the heart-shaped stay area.

[0021] When the sliding shaft portion stays in the heart-shaped staying area and the sliding element is pressed and slid relative to the rebound bracket, the sliding element and / or the auxiliary part slides out of the heart-shaped staying area through the heart groove guide part and drives the sliding shaft portion to slide out of the heart-shaped staying area and slide on the upper limit sliding area. When the sliding shaft portion slides to a certain position on the upper limit sliding area, it buffers and slides from the conversion area to the lower limit sliding area; wherein, the pushing element and / or the sliding element slides out of the rebound bracket by pressing the elastic part when the sliding shaft portion slides out of the heart-shaped staying area.

[0022] The core groove sliding-in guide part, the core groove sliding-in buffer part, the inclined guide part, the core groove sliding-out guide part, and the conversion area are respectively composed of at least one curved segment, and the curvatures of the curved segments are the same or different; the core groove sliding-in guide part, the core groove sliding-in buffer part, the inclined guide part, the core groove sliding-out guide part, and the conversion area interact with the sliding shaft part through the curved segments.

[0023] The present invention has the following advantages compared with the prior art through the improvement of the above structure:

[0024] 1. When in use, the user drives the sliding element to slide into the rebound bracket through an external driving device. When sliding, the sliding element will act through the core groove sliding guide part and drive the sliding shaft part to slide on the lower limit sliding area. When the sliding shaft part slides to a certain position, it will be separated from the core groove sliding guide part, and rely on and act on the core groove sliding buffer part and the inclined guide part. The sliding shaft part guides the buffer to slide in and is temporarily positioned on the temporary part and the pause area through the action of the core groove sliding buffer part and the inclined guide part. At this time, the sliding element can slide elastically with the auxiliary part when the sliding shaft part and the core groove sliding guide part are separated, thereby avoiding the problem that the pressing and rebounding device and the external driving device cannot function normally due to errors in the assembly position, so as to simplify the process of assembling the pressing and rebounding device and the driving device with the movable parts and the fixed parts of the furniture respectively. When the sliding shaft is temporarily positioned on the temporary part and the pause area, and the sliding element slides elastically with the auxiliary part through the auxiliary elastic part, the sliding shaft will be separated from the temporary part and the pause area, and guided to slide on the inclined guide part and stay in the heart-shaped stay area, so as to finally realize the positioning of the push element and the sliding element in the rebound bracket. Since the heart groove slides into the buffer part, the inclined guide part, and the guiding buffer of the inclined guide part, the collision between the sliding shaft and the push element, the sliding element, and the auxiliary part can be avoided when sliding, and the sliding shaft can slide into and stay in the heart-shaped stay area without collision, abnormal noise, and silently, and the rebound bracket, the pushing element, and the sliding element can be prevented from being loosely assembled due to inaccurate production size and assembly position, and collision, abnormal noise, and other problems occur when the sliding shaft slides into and stays in the heart-shaped stay area, thereby improving the compactness of the connection between the components of the press-rebound device and the service life.

[0025] When the sliding shaft portion stays in the heart-shaped stay area and the user presses the sliding element to slide relative to the rebound bracket, the sliding element and / or the auxiliary part slides out of the heart-shaped stay area through the heart groove guide portion and drives the sliding shaft portion to slide out of the heart-shaped stay area and slide on the upper limit sliding area. When the sliding shaft portion slides to a certain position on the upper limit sliding area, it buffers and slides from the conversion area to the lower limit sliding area, so as to finally realize the sliding extension of the push element and the sliding element out of the rebound bracket. Due to the buffering effect of the conversion area, the sliding shaft portion can slide from the upper limit sliding area to the lower limit sliding area without collision, abnormal noise, and silently, thereby avoiding the problem that the sliding shaft portion is stuck due to non-standard assembly position and cannot enter the lower limit sliding area normally. At the same time, it can further solve the problem that the rebound bracket, the push element, and the sliding element are loosely assembled due to inaccurate production size and assembly position, and the sliding shaft portion encounters collisions and abnormal noises when sliding from the upper limit sliding area to the lower limit sliding area.

[0026] 2. The core groove sliding-in guide part, the core groove sliding-in buffer part, the inclined guide part, the core groove sliding-out guide part, and the conversion area do not interfere with each other during operation, and are respectively composed of at least one tortuous section. Therefore, when the pushing element and the sliding element are closed relative to the rebound bracket, the elastic force of the pressing elastic part on the pushing element can be offset by the matching parts of the core groove sliding-in guide part, the core groove sliding-in buffer part, and the inclined guide part, so that the pushing element and the sliding element can automatically slide into and position in the rebound bracket through their own inertia; when the pushing element and the sliding element slide out and open relative to the rebound bracket, the elastic locking force of the pressing elastic part on the pushing element can also be offset by the core groove sliding-in guide part, so that the user can use less pressing force to drive the pushing element and the sliding element to automatically slide out of the rebound bracket, thereby effectively improving the user's experience; the conversion area can convert the pop-up force of the pressing elastic part on the pushing element and the sliding element to avoid excessive pop-up force, which leads to collision, abnormal noise and other problems of the rebound bracket, the pushing element and the sliding element.

[0027] 3. The upper limit sliding area, the conversion area, the lower limit sliding area, the pause area, and the heart-shaped stop area are connected end to end, which can effectively force the sliding shaft part to slide only in a sequential direction along the trajectory of the heart-shaped slide groove, thereby avoiding the problem that the sliding shaft part of the prior art cannot be positioned on the pushing element, and is easily displaced on the pushing element during transportation or use, causing the sliding shaft part to be stuck on the pushing element and unable to be positioned and slide along the trajectory of the heart-shaped slide groove, making the product more stable in use.

[0028] 4. The size of the pause area is comparable to that of the sliding shaft portion. At the same time, due to the elastic effect of the auxiliary elastic member, the pressing elastic member, and the sliding elastic member, when the sliding shaft portion is temporarily positioned in the temporary portion and the pause area, there will be no up-down, left-right, front-back displacement problems. This not only improves the stability of the product, but also avoids the problem that the core groove of the sliding element slides into the guide portion and cannot be separated from the sliding shaft portion, resulting in the sliding element and the sliding shaft portion being stuck to each other, thereby reducing the production error of the press-rebound device and the assembly error of the press-rebound device and the external drive device, thereby further ensuring that the press-rebound device and the external drive device can interact normally without being affected by the assembly position.

[0029] In general, it has the characteristics of simple and reasonable structure, low manufacturing cost, reliable performance, compact connection between components, quiet and no abnormal noise during opening and closing, high flexibility, long service life and wide range of use, and strong practicality.

[0042] When the sliding shaft portion 5 is temporarily positioned on the temporary portion 9 and the pause area 10, and the sliding element 3 and the auxiliary component 7 elastically return to slide with each other, the sliding shaft portion 5 is disengaged from the temporary portion 9 and the pause area 10, and is guided to slide on the inclined guide portion 13 and stay in the heart-shaped stay area 12; wherein, the pushing element 2 and / or the sliding element 3 are positioned in the rebound bracket 1 when the sliding shaft portion 5 stays in the heart-shaped stay area 12.
