Description

Technical Field

[0001] This application relates to the technical field of hardware fittings, and particularly to a power recovery structure for a double-opening sliding door. Background Art

[0002] Double-opening sliding doors are widely used in the fields of home, office, and industry, and their opening and closing methods usually rely on manual or electric drive. With the increasing requirements of users for the convenience and stability of door operation, a traction rope anti-sway mechanism is mostly adopted in the prior art to enhance the stability of the door body. However, the traditional winding methods of traction ropes (such as X-shaped and Z-shaped) have problems of large space occupation and low power transmission efficiency, resulting in insufficient power during the opening and closing of the door body and affecting the user experience. In addition, there is a lack of an effective power recovery mechanism in the prior art, and the efficient utilization of energy cannot be achieved during the opening and closing process of the door body.

[0003] Currently, the anti-sway mechanism of double-opening sliding doors is mainly achieved through the winding method of traction ropes. Common winding methods include X-shaped and Z-shaped. The X-shaped winding realizes multi-point fixation of the door body through crossed traction ropes, but its structure is complex and occupies a large space; the Z-shaped winding reduces the space occupation through a zigzag traction rope, but it performs poorly in power transmission and anti-sway effect. In addition, some technologies attempt to improve the stability of door opening and closing by adding springs or dampers, but these solutions often cannot take into account both power recovery and anti-sway effect, and have complex structures and high costs.

[0004] The X-shaped and Z-shaped winding methods of traction ropes in the prior art occupy a large space, resulting in insufficient power for the opening and closing of the door body; the stability of the anti-sway mechanism is poor and cannot meet the high-precision opening and closing requirements; there is a lack of an effective power recovery mechanism, and the energy utilization rate is low.

The elastic portion 94 has elasticity.

[0052] Specifically, the locking branch 91 includes a locking box.

[0053] Specifically, the clamping lock portion 92 includes a clamping lock upper support plate 920, a clamping lock lower support plate 921, a first clamping block 922, a second clamping block 923, a clamping rail piece 924, a clamping rail pressing piece 925 and an unlocking spring column 926. The clamping lock upper support plate 920 covers the clamping lock lower support plate 921, and a clamping lock sliding column 928 is installed on the clamping lock upper support plate 920. One end of the clamping lock sliding column 928 is fixedly connected to the clamping lock upper support plate 920, and the other end passes through the clamping lock lower support plate 921 and is slidably connected to the clamping lock lower support plate 921. In addition, a flange is convexly provided on the clamping lock sliding column 928 and is clamped to the surface of the clamping lock lower support plate 921, so that the clamping lock upper support plate 920 is stably covered on the clamping lock lower support plate 921.

[0054] One end of the unlocking spring column 926 is clamped to the clamping lock lower support plate 921. One ends of the first clamping block 922 and the second clamping block 923 are respectively hinged to the lower support plate, and a torsion spring 927 is installed at each hinge point. In addition, one ends of the torsion springs 927 are both abutted against the unlocking spring column 926. The clamping rail pressing piece 925 is slidably installed on the clamping lock lower support plate 921. One end of the clamping rail piece 924 is hinged to the clamping rail pressing piece 925, and the other end is clamped to the rail guiding portion 93.

[0055] Specifically, the rail guiding portion 93 includes a Y-shaped sliding groove 930 and a locking groove 931 opened on the clamping lock lower support plate 921. The Y-shaped sliding groove 930 and the locking groove 931 are communicated. The clamping rail piece 924 is slidably connected to the Y-shaped sliding groove 930, and when the cabinet door is locked, the clamping rail piece 924 is located in the locking groove 931.

[0056] The elastic portion 94 includes two elastic springs, and the two elastic springs are respectively installed at the upper and lower ends of the locking box. The elastic springs are used to provide a reaction force for the clamping lock portion 92. The clamping portion 16 on the middle branch 51 includes a clamping rod. When the cabinet door is locked, the clamping rod is clamped by the first clamping block 922 and the second clamping block 923.

[0057] Locking principle: Open the cabinet door and push it to the side of the cabinet body 1. The clamping part 16 on the middle support part 51 abuts against the clamping lock part 92 until the clamping part 16 abuts against the first clamping block 922 and the second clamping block 923 at the same time. The clamping part 16 pushes the upper clamping lock plate 920 and the lower clamping lock plate 921 to slide. The clamping rail piece 924 slides along the Y-shaped chute 930 towards the lock groove 931. At the same time, the clamping rail piece 924 abuts against the inner end part of the locking box, and reversely pushes the upper clamping lock plate 920. The upper clamping lock plate 920 pushes the unlocking spring column 926 into a compressed state. The unlocking spring column 926 pushes two torsion springs 927, and the two torsion springs 927 are in an energy storage state. The first clamping block 922 and the second clamping block 923 open. The clamping part 16 is clamped between the first clamping block 922 and the second clamping block 923. Withdraw the force pushing the cabinet door. The first clamping block 922 and the second clamping block 923 are clamped under the action of the two torsion springs 927, and the clamping part 16 is locked. At the same time, the clamping rail piece 924 moves reversely under the action of the elastic part 94 and slides into the lock groove 931. The upper clamping lock plate 920 and the lower clamping lock plate 921 are locked, and the cabinet door is locked. At this time, the energy storage coiled spring is stretched and in an energy storage state; the elastic part 94 is also in an energy storage state. When unlocking the cabinet door, push the cabinet door once. The cabinet door slowly moves out from the side of the cabinet body 1 under the action of the energy storage coiled spring. At the same time, the clamping part 16 pushes the upper clamping lock plate 920 and the lower clamping lock plate 921 to move. The unlocking spring column 926 is compressed by the force and pushes open the two torsion springs 927. The first clamping block 922 and the second clamping block 923 open. The clamping part 16 is separated from the first clamping block 922 and the second clamping block 923 under the action of the energy storage coiled spring. At this time, the clamping rail piece 924 is separated from the lock groove 931. The upper clamping lock plate 920 and the lower clamping lock plate 921 are reset along the Y-shaped chute 930 under the reaction force of the elastic part 94, and the clamping rail piece 924 also drives the reset synchronously. The above solution realizes the locking and automatic ejection of the cabinet door, can effectively utilize the kinetic energy in the process of opening and closing the cabinet door and convert it into potential energy and store it in the energy storage part 32. When the cabinet door is closed, the energy storage part 32 releases the stored potential energy to assist the cabinet door to close smoothly, significantly reducing the resistance during the closing process of the cabinet door and improving the user's operation experience. At the same time, it can achieve precise locking when the cabinet door is in an energy storage state, avoid accidental movement of the cabinet door, and ensure the structural stability and safety.

[0058] See Figure 10 , Further, buffer limit members 10 are respectively provided on the upper rail part 13 and the lower rail part 15 of the first sliding door 11 and the second sliding door 12. The buffer limit members 10 are used to limit the sliding range of the first sliding door 11 and the second sliding door 12 to prevent the cabinet door from disengaging from the upper rail part 13, the middle rail part 14 and the lower rail part 15.

[0059] Specifically, the buffer limit member 10 includes a buffer housing 100, a buffer spring 101, a buffer oil cylinder 103, a buffer push rod 102, a first limit block 104 and a second limit block 105.

[0060] The buffer housing 100 is fixedly installed on the upper rail part 13 or the lower rail part 15. The buffer oil cylinder 103 is slidably installed in the buffer housing 100, and the output end of the buffer oil cylinder 103 is clamped in the buffer housing 100. A clamping block is fixedly installed in the buffer housing 100, and the output end of the buffer oil cylinder 103 is clamped on the clamping block. The buffer push rod 102 is slidably installed in the buffer housing 100. One end of the buffer push rod 102 abuts against the inner wall of the buffer housing 100, and the other end is fixedly connected to the body of the buffer oil cylinder 103. The first limiting block 104 is fixedly installed at one end of the buffer push rod 102, and is located at the end where the buffer push rod 102 abuts against the buffer housing 100. One end of the second limiting block 105 is hinged to the second limiting block 105, and the second limiting block 105 is a plastic elastic block. The buffer spring 101 is installed in the buffer housing 100. One end of the buffer spring 101 abuts against the inner wall of the buffer housing 100, and the other end is fixedly connected to the output end of the buffer oil cylinder 103. A third limiting block 23 is respectively arranged on the load-bearing part 41 and the lower branch part 61. When the cabinet door is closed, the third limiting block 23 is clamped by the first limiting block 104 and the second limiting block 105.

[0061] See Figure 4 and Figure 10 , buffer principle: When the cabinet door is opened and pushed to the side of the cabinet body 1, the cabinet door synchronously drives the third limiting block 23 on the load-bearing part 41 and the lower branch part 61 to move. The third limiting block 23 pushes the buffer push rod 102 to move. The buffer push rod 102 pushes the buffer oil cylinder 103 to slide. The output end of the buffer oil cylinder 103 contracts, and a section exposed outside the body pushes the buffer spring 101 to compress until the buffer oil cylinder 103 cannot move. The third limiting block 23 disengages from the first limiting block 104 and the second limiting block 105. At this time, the cabinet door continues to move until the locking component 9 locks the cabinet door. The acting force of the buffer spring 101 pushes the buffer push rod 102 to retreat a certain distance, and the buffer spring 101 can reduce the impact force received by the buffer oil cylinder 103.

[0062] When the cabinet door is closed, the cabinet door disengages from the locking component 9, and the cabinet door is reset under the action of the power recovery component 3. The third limiting block 23 approaches the second limiting block 105. When contacting the second limiting block 105, it pushes the second limiting block 105 to reset. The second limiting block 105 drives the buffer push rod 102 to reset. The piston rod of the buffer oil cylinder 103 gradually pulls out from the body, so that the buffer oil cylinder 103 decelerates the kinetic energy of the power recovery component 3 acting on the cabinet door, avoiding the cabinet door closing too fast. Until the cabinet door pops out from the side of the cabinet body 1, the third limiting block 23 is clamped into the first limiting block 104 and the second limiting block 105, and the cabinet door reaches the closed position, thereby restricting the sliding range of the cabinet door on the upper rail part 13 and the lower rail part 15, and avoiding the cabinet door disengaging from the upper rail part 13, the middle rail part 14 and the lower rail part 15.

[0063] The working principle of the power recovery structure of a double-opening sliding door in this application is as follows: The power recovery structure of the double-opening horizontal sliding door realizes its function through the coordinated operation of the stabilizing component 2 and the power recovery component 3.

[0064] Stabilizing component 2: The load-bearing part 41 (including the load-bearing wheel 410 and the upper rail pulley 412) of the upper stabilizer 4 slides along the upper slide rail of the cabinet body 1 to bear the weight of the door body. The upper traction steel rope is wrapped around the upper guide wheel with a triangular distribution in an "J" shape, one end of which is connected to the load-bearing part 41, and the other end is connected to the middle stabilizer 5. The tension of the steel rope is adjusted by the fixed adjustment part 73 (such as a fixed screw) to dynamically balance the traction force. The middle rail pulley of the middle stabilizer 5 slides along the middle slide rail and is connected to the upper and lower traction steel ropes to form a multi-point support. The lower rail pulley of the bottom stabilizer 6 slides along the lower slide rail, and the lower traction steel rope is also wrapped around the lower guide wheel in an "J" shape to connect the middle stabilizer 5. The three are fixed to the cabinet door through an aluminum connecting column. The triangular distribution of the guide wheels and the "J" shaped winding path are used to automatically compensate for the gap caused by long-term use, ensuring that the trajectory is stable when the door body moves horizontally, reducing space occupancy and improving power transmission efficiency.

[0065] Power recovery component 3: One end of the energy storage coil spring (energy storage part 32) is fixed to the energy storage box of the cabinet body 1, and the other end is connected to the middle stabilizing part 5. When the door is opened, the coil spring is stretched to store energy, and the locking component 9 (including the clamping part 92 and the elastic spring) locks the door body through the cooperation of the clamping rod (clamping part 16) and the clamping block to store kinetic energy; when the door is closed, the coil spring releases potential energy to assist the door body to close smoothly, and at the same time the elastic part 94 provides a reaction force to realize the automatic pop-up and precise locking of the cabinet door, reducing the closing resistance.

[0066] Through the collaborative design of "multi-level stabilizer + J-shaped traction rope + power recovery", the following effects are achieved: the stabilizer component 2 ensures that there is no shaking or offset when the cabinet door is opened and closed, and the power recovery component 3 realizes kinetic energy storage and potential energy release, assists the cabinet door to close and provides a locking function. Compared with the traditional structure, the "J-shaped" winding method optimizes the layout of the traction rope, reduces power loss, and reduces space occupancy by more than 50%; the dynamic gap compensation mechanism makes the long-term use error of the cabinet door less than 0.5mm, and the stability is improved by 70%; the energy storage coil spring assists in closing, reducing the closing resistance by 60%, and the operating force is ≤5N; the locking component 9 realizes "one touch to lock, one touch to open", and the locking reliability reaches 99.5%. It effectively solves the problems of offset shaking, large closing resistance, unreliable locking, etc. caused by gap accumulation in traditional flat sliding doors, and significantly improves the service life and user experience of the cabinet door.
