Description

Technical Field

[0001] The invention relates to the field of hardware accessories, in particular to a spring-free driven cabinet door rebounder. Background Art

[0002] Existing cabinet door rebounders, especially push-type cabinet door rebounders, usually rely on springs and complex rebound control mechanisms to achieve their functions. These traditional designs generally include springs, latches, and other cooperating components, which store and release energy through the elastic deformation of the springs to drive the cabinet door to open and close. For example, in a push-type cabinet door rebounder, when the user presses the cabinet door, the spring is compressed to store energy, and then the energy is released through the rebound control mechanism to push the cabinet door to open. However, this traditional spring-based design has the following significant disadvantages: Complex structure: Traditional push-type cabinet door rebounders require integrated springs and complex rebound control mechanisms, such as multi-stage latches or damping devices, to ensure that the cabinet door can be smoothly and reliably opened after being pressed. This design usually involves multiple moving parts, resulting in a complex overall structure. The complex structure not only increases the difficulty of design and assembly, but may also reduce the stability of the device due to the interaction between components.

[0003] High manufacturing cost: Due to the need for springs, latches and other precision parts, the manufacturing process of traditional cabinet door rebounders is relatively cumbersome, and the material and processing costs are high. In particular, the damping or guide components in the rebound control mechanism often require high manufacturing precision, further pushing up production costs.

[0004] Limited service life: As a core component, the spring will fatigue due to repeated compression and release during long-term use, resulting in weakened elasticity or even breakage. This wear and aging phenomenon significantly shortens the service life of the rebounder, bringing additional replacement costs to users. Therefore, it is necessary to make further improvements to it. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the existing technology and provide a new cabinet door rebounder with a simple structure, easy use, and the ability to eliminate the use of springs and simplify the rebound control mechanism, so as to reduce the structural complexity, reduce the manufacturing and maintenance costs, and at the same time improve the reliability and service life of the device. A spring-free driven cabinet door rebounder.

[0006] The object of the present invention is achieved by the following method: a spring-free driven cabinet door rebounder, comprising a fixed shell installed in a cabinet, a hollow interior of the fixed shell is provided with a turning cavity; a turning frame is rotatably installed in the turning cavity, and a first magnet is installed on the turning frame; A guide groove is extended inwardly from the front end surface of the fixed shell, and a driving arm is slidably installed in the guide groove. The driving arm is linked with the flip frame, and the flip frame is pushed to swing by pressing the driving arm, so that the first magnet on the flip frame rotates from an upward state to a forward state; It also includes a second magnet installed on the cabinet door, and the magnetic pole direction of the second magnet is the same as the magnetic pole direction of the first magnet.

[0007] Furthermore, a hinge seat is symmetrically arranged in the flip chamber, and hinge shafts are extended outwardly at the left and right ends of the flip frame. The flip frame is rotatably installed in the hinge seat through the hinge shaft.

[0008] Furthermore: the guide groove is arranged on the outer side of one of the hinge seats, and a linkage arm is arranged on the hinge shaft on the same side, and the linkage arm extends into the guide groove and is connected with the driving arm.

[0009] Furthermore: a pushing step is provided on one side of the driving arm facing the linkage arm, and the pushing step presses against the linkage arm.

[0010] Furthermore: an anti-slip block is extended outwardly from the side wall of the driving arm.

[0011] Furthermore: a counterweight block is also arranged on the flip frame, and under normal conditions, the counterweight block is located at the bottom to push the first magnet to tilt upward.

[0012] Furthermore: the surface of the second magnet is covered with a protective cover, and the protective cover is embedded in the door body.

[0013] Furthermore: the first magnet and the second magnet are permanent magnets.

[0014] The beneficial effects of the present invention are: 1. Simple structure, low production cost and improved market competitiveness.

[0015] 2. The present invention adopts a magnetic repulsion mechanism to replace the spring and complex rebound control system, significantly reducing the number of moving parts. This simplified design makes the device easier to design, assemble and maintain, and avoids the complexity caused by the coordinated work of multiple parts in traditional designs.

[0016] 3. Since the precision springs and complex mechanical parts are omitted, the material and production costs of the present invention are greatly reduced. The use of standardized permanent magnets and simplified mechanical structures not only reduces the processing difficulty, but also improves the cost-effectiveness of the production process.

[0017] 4. The present invention has a simple design, a small number of parts, and a more intuitive and efficient installation process. Compared with the traditional rebounder that requires precise alignment of multiple moving parts, the present invention reduces the installation time and professional skills requirements and reduces the incidence of installation errors.

[0018] 5. The present invention avoids using springs that are prone to fatigue and breakage, and instead uses durable permanent magnets and a stable mechanical linkage structure. The permanent magnets will not lose their performance due to long-term use, thereby significantly extending the service life of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention is further described in detail below with reference to the accompanying drawings. A spring-free driven cabinet door rebounder comprises a fixed shell 2 installed in a cabinet body 1, wherein a turning cavity 21 is provided in a hollow space inside the fixed shell 2; a turning frame 3 is rotatably installed in the turning cavity 21, and a first magnet 4 is installed on the turning frame 3; The front end surface of the fixed shell 2 is extended inwardly to form a guide groove 22, and a driving arm 5 is slidably installed in the guide groove 22. The driving arm 5 is linked with the flip frame 3. Pressing the driving arm 5 pushes the flip frame 3 to swing, so that the first magnet 4 on the flip frame 3 rotates from an upward state to a forward state. It also includes a second magnet 7 mounted on the cabinet door 6 , and the magnetic pole orientation of the second magnet 7 is the same as that of the first magnet 4 .

[0029] The core component of the device includes a fixed shell installed in the cabinet, a hollow flip cavity is provided inside the fixed shell, a flip frame is installed in the flip cavity by rotation, and a first magnet is fixed on the flip frame. The front end of the fixed shell extends inward to form a guide groove, and a driving arm is slidably installed in the guide groove. The driving arm is connected to the flip frame through a linkage mechanism. In addition, a second magnet is installed on the cabinet door, and its magnetic pole direction is the same as that of the first magnet.

[0030] like Figure 5 , 7 As shown, under normal conditions: the first magnet is in an upward state, and the cabinet door is in a closed position under the resetting action of the self-resetting hinge 9. At this time, the first magnet and the second magnet are not directly aligned, the magnetic force is weak, and the cabinet door remains closed.

[0031] like Figure 6 , 8 As shown, when the user presses the cabinet door, the cabinet door pushes the driving arm inward, causing the driving arm to slide inward along the guide groove. During the sliding process of the driving arm, the flip frame is pushed to swing around its rotation axis through linkage with the flip frame. The swing of the flip frame drives the first magnet to rotate from an upward state to a forward state, so that the first magnet is opposite to the front of the second magnet on the cabinet door. Since the magnetic poles of the first magnet and the second magnet are in the same direction, such as both the N pole or the S pole is facing forward, the two produce a magnetic repulsion effect. When the user completes pressing and releases the cabinet door, the repulsive force pushes the cabinet door to open a gap outward, and the user can open the cabinet door through the gap.

[0032] Compared with traditional technologies, this case uses a magnetic repulsion mechanism to replace traditional springs and complex mechanical structures, reducing moving parts and simplifying the overall design. At the same time, springs and precision parts are eliminated, reducing manufacturing and material costs, reducing mechanical failure points, and enhancing the stability of the device.

[0033] In one embodiment, the flip chamber 21 is symmetrically provided with an articulated seat 23, and the flip frame 3 is provided with an articulated shaft 31 extending outward at both ends. The flip frame 3 is rotatably installed in the articulated seat 23 via the articulated shaft 31. When the driving arm is pressed and the flip frame is pushed through the linkage mechanism, the flip frame uses the articulated shaft as a fulcrum to achieve a smooth swinging motion in the articulated seat. The symmetrical articulated seat provides stable support for the flip frame, ensuring that it will not deflect or shake during the rotation process. At the same time, the symmetrical articulated seat design and the rotatable installation method of the articulated shaft improve the stability and durability of the rotation of the flip frame.

[0034] In one of the embodiments, the guide groove 22 is arranged on the outside of one of the articulated seats 23, and a linkage arm 32 is arranged on the articulated shaft 31 on the same side, and the linkage arm 32 extends into the guide groove 22 and is connected to the driving arm 5. When the user presses the cabinet door, the driving arm slides inward along the guide groove. When the driving arm slides, it contacts the linkage arm and pushes the linkage arm to move, and the linkage arm then drives the articulated shaft and the flip frame to rotate, realizing the state switching of the first magnet. In this embodiment, the cooperation of the guide groove and the linkage arm realizes the precise linkage between the driving arm and the flip frame, ensuring the reliability of the motion transmission. At the same time, the guide groove is arranged on the outside of the articulated seat to make full use of the space and make the overall structure of the device more compact.

[0035] In one embodiment, the driving arm 5 is provided with a pushing step 51 on the side facing the linkage arm 32, and the pushing step 51 presses against the linkage arm 32. When pressing the cabinet door, the driving arm slides inward along the guide groove, and the pushing step presses against the linkage arm, transmitting the force to the linkage arm. After the linkage arm is subjected to the force, the flip frame is driven to rotate, and the design of the pushing step ensures that the force is effectively transmitted when pressing, and does not interfere with the resetting of the flip frame after releasing. At the same time, the pressing method realizes direct and effective force transmission and reduces energy loss.

[0036] In one embodiment, the side wall of the driving arm 5 extends outwardly to form an anti-drop block 52. In this embodiment, the side wall of the driving arm extends outward to form an anti-drop block, and the anti-drop block cooperates with the inner wall of the guide groove to limit the sliding range of the driving arm. When the driving arm slides in the guide groove, the anti-drop block prevents it from falling off the guide groove due to excessive sliding or external force, thereby ensuring the stability of the device during operation. The anti-drop design prevents accidental falling of components and enhances the reliability and safety of the device.

[0037] In one of the embodiments, a counterweight 33 is further provided on the flip frame 3. Under normal circumstances, the counterweight 33 is located at the bottom to push the first magnet 4 to tilt upward. Therefore, under normal circumstances, when there is no external force pressing, the counterweight is located at the bottom of the flip frame due to the action of gravity, so that the flip frame remains stable and the first magnet is pushed to an upward state. After the pressing operation is completed, the external pressure is released, and the counterweight drives the flip frame to reset by gravity, and the first magnet returns to an upward state to prepare for the next operation. The counterweight replaces the traditional spring to realize the reset function, avoids the problem of spring fatigue, and prolongs the service life. At the same time, the gravity effect is stable and reliable, and is not easily affected by environmental factors, ensuring the long-term effectiveness of the reset function.

[0038] In one of the embodiments, the surface of the second magnet 7 is covered with a protective cover 8, and the protective cover 8 is embedded in the door body. The protective cover covers the second magnet to prevent it from being affected by external impact, dust or moisture, thereby ensuring the stability of the magnet performance. At the same time, the protective cover is embedded in the door body, so that the second magnet is firmly fixed on the cabinet door, and cooperates with the first magnet to achieve a rebound function. At the same time, the protective cover improves the durability and safety of the second magnet and extends its service life. In addition, the hidden embedded design keeps the cabinet door clean and tidy, and improves the overall aesthetics of the furniture.

[0039] In one embodiment, the first magnet 4 and the second magnet 7 are permanent magnets. The magnetic force of the permanent magnets will not decay due to prolonged use, thus ensuring the long-term operation stability of the device.

[0040] In summary, the spring-free driven cabinet door rebounder of the present invention realizes the push-and-rebound function of the cabinet door through innovative magnetic repulsion and simplified mechanical linkage mechanism. The magnetic mechanism and simple linkage replace springs and complex mechanisms, reducing the number of components. At the same time, springs and precision components are omitted, reducing manufacturing and material costs, so it can be widely promoted and used.
