Description

Technical Field

[0001] The present 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 improvement of users' requirements 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 the traction rope (such as the X-type and Z-type) have problems of large space occupation and low power transmission efficiency, resulting in insufficient power when the door body opens and closes, which affects 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] At present, the anti-sway mechanism of double-opening sliding doors is mainly realized by the winding method of the traction rope. The common winding methods include the X-type and Z-type. The X-type winding realizes multi-point fixation of the door body through the crossed traction ropes, but its structure is complex and it occupies a large space; the Z-type winding reduces the space occupation through the folded traction rope, but it performs poorly in power transmission and anti-sway effect. In addition, some technologies attempt to improve the stability of the door body 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-type and Z-type winding methods of the traction rope in the prior art occupy a large space, resulting in insufficient power for the door body to open and close; 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. Summary of the Invention

The hinge piece on the connecting piece is fixedly connected to the first sliding door or the second sliding door, which can transmit power during the movement of the door body, ensure the door body slides smoothly along the predetermined track, and avoid the problems of large space occupation and low power transmission efficiency existing in the traditional X-type and Z-type winding connection methods, thereby improving the smoothness of the door body opening and closing and the user experience.

The multiple upper guiding parts are distributed in a triangular shape, making the winding connection of the upper traction part more compact, reducing the space occupation while improving the power transmission efficiency. The first fixing component between the upper traction part and the load-bearing part further enhances the structural stability, avoiding the swinging or jamming phenomenon of the cabinet door caused by uneven force during the movement, thereby improving the smoothness of the cabinet door opening and closing and the user experience.

One end of the fixing adjusting part is rotatably connected to the fixing sliding part, and the other end passes through the fixing branch.

[0023] By adopting the above technical solution, the structural design of the first fixing component can achieve precise adjustment and fixation of the connection between the upper traction part and the load-bearing part. Specifically, the fixing branch provides an installation basis for the entire fixing component, ensuring its stable connection on the load-bearing part, thereby improving the reliability of the overall structure; the sliding design of the fixing sliding part allows the upper traction part to adjust its position within a certain range to adapt to the tension change generated during the movement of the door body. The limiting part further limits the sliding direction of the fixing sliding part, avoiding unnecessary displacement that may cause structural failure; the rotational connection and clamping design of the fixing adjusting part enable the position of the fixing sliding part to be finely adjusted and locked according to actual needs, enhancing the flexibility and stability of the structure, and ensuring that the upper traction part can maintain a stable connection under different working conditions.

Multiple middle boosting parts are slidably connected to the middle rail part, reducing the frictional resistance and ensuring the smooth movement of the cabinet door. The upper traction part is fixedly connected to the middle support, realizing the effective transmission of the traction force, and further enhancing the stability and power transmission efficiency during the opening and closing process of the cabinet door.

[0029] Preferably, the bottom stabilizing member includes:

[0034] The lower traction part and the lower support are connected by a second fixing member.

[0035] By adopting the above technical solutions, the bottom stabilizing member can effectively improve the stability of the double-opening sliding door during the opening and closing process. Specifically, the fixed connection of the lower support to the connecting piece and the sliding connection to the lower rail part ensure that the cabinet door is evenly stressed during the movement, avoiding the occurrence of swinging and blocking phenomena. The setting of multiple lower boosting parts further enhances the sliding smoothness between the lower support and the lower rail part, improving the reliability of the overall structure. Multiple lower guiding parts distributed in a triangular shape optimize the winding path of the traction rope, reducing the space occupation and improving the power transmission efficiency.

The lower traction part and the lower support are connected by a second fixing member, ensuring the firmness and adjustability of the structure and adapting to the requirements of different usage scenarios.

[0036] Preferably, the upper traction part is wound around multiple upper guiding parts in a zigzag shape.

[0037] By adopting the above technical solution, the upper traction part is wound around a plurality of upper guiding parts in a "J" shape, enabling the traction rope to form a more compact structure when transmitting power, reducing space occupation, and improving the power transmission efficiency at the same time. Compared with the traditional X-shaped and Z-shaped winding methods, the "J" shape winding method can optimize the force distribution while ensuring the stability of the door opening and closing, avoiding the phenomenon of swinging or jamming during the movement of the door, thus enhancing the user experience. In addition, this winding method helps to further enhance the anti-swing effect and meet the high-precision opening and closing requirements.

[0043] A locking component is provided on the middle rail part, and the locking component is used to lock the cabinet door in the energy storage state.

[0044] By adopting the above technical solution, the power recovery component can effectively utilize the kinetic energy during the opening and closing of the cabinet door and convert it into potential energy and store it in the energy storage part. When the cabinet door is closed, the energy storage part 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 enhancing the user's operation experience.

[0050] By adopting the above technical solutions, the locking component can effectively lock the cabinet door in the energy storage state, preventing the cabinet door from accidentally moving due to external forces during the opening or closing process. Specifically, the locking support part serves as a fixed foundation to ensure the stability of the entire locking structure and provides an installation and movement reference for the clamping and locking part. The clamping and locking part cooperates with the clamping part on the middle support part to achieve precise locking of the position of the cabinet door, preventing the cabinet door from shaking or sliding in the non-operating state. The rail guiding part guides the movement trajectory of the clamping and locking part and further enhances the reliability of locking through the clamping function, ensuring that the clamping and locking part operates accurately without error.

[0051] The elastic characteristics of the elastic part enable the clamping and locking part to have buffering ability during the locking and unlocking processes, reducing mechanical shock, extending the service life of the components, and improving the smoothness of operation at the same time.

[0089] See Figures 7 to 9, the locking member 9 includes a locking branch 91, a clamping lock portion 92, a rail guiding portion 93 and an elastic portion 94. The locking branch 91 is fixedly installed on the middle branch 51; the clamping lock portion 92 is slidably installed on the locking branch 91. A clamping portion 16 is provided on the middle branch 51, and the clamping portion 16 is clamped to the clamping lock portion 92, and the clamping lock portion 92 is used to lock the clamping portion 16; the clamping lock portion 92 is slidably connected to the rail guiding portion 93, and the rail guiding portion 93 is used to guide the movement of the clamping lock portion 92 and lock the clamping lock portion 92; one end of the elastic portion 94 is fixedly connected to the locking branch 91, and the other end is fixedly connected to the clamping lock portion 92, and the elastic portion 94 has elasticity.

[0090] Specifically, the locking branch 91 includes a locking box.

[0091] 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 stably covers the clamping lock lower support plate 921.

[0092] 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.

[0093] 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.

[0094] 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, and when the cabinet door is locked, the clamping rod is clamped by the first clamping block 922 and the second clamping block 923.

[0095] Locking principle: Open the cabinet door and push it against the side of the cabinet body 1. The clamping part 16 on the middle branch 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 simultaneously. 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 of the locking box, pushing the upper clamping lock plate 920 in the reverse direction. 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. Remove 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 in the reverse direction 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 disengages 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 disengages from the lock groove 931. The upper clamping lock plate 920 and the lower clamping lock plate 921 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 during the opening and closing process of 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 the energy storage state, avoid accidental movement of the cabinet door, and ensure the structural stability and safety.

[0096] See Figure 10 , Further, buffer limiters 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 limiters 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.

[0097] Specifically, the buffer limiter 10 includes a buffer shell 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.

[0098] 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 limit 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 limit block 105 is hinged to the second limit block 105, and the second limit 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 limit block 23 is respectively arranged on the load-bearing part 41 and the lower support part 61. When the cabinet door is closed, the third limit block 23 is clamped by the first limit block 104 and the second limit block 105.

[0099] 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 limit block 23 on the load-bearing part 41 and the lower support part 61 to move. The third limit 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 limit block 23 disengages from the first limit block 104 and the second limit 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.

[0100] When the cabinet door is closed, the cabinet door disengages from the locking component 9. The cabinet door is reset under the action of the power recovery component 3. When the third limit block 23 approaches the second limit block 105 and contacts the second limit block 105, it pushes the second limit block 105 to reset. The second limit 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 to avoid the cabinet door closing too fast. Until the cabinet door pops out from the side of the cabinet body 1, the third limit block 23 is clamped into the first limit block 104 and the second limit 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.

[0101] The working principle of the power recovery structure of a double-opening sliding door in this application is as follows:

[0102] The power recovery structure of the double-opening sliding door realizes its functions through the coordinated operation of the stability component 2 and the power recovery component 3.

[0103] Stability component 2: The load-bearing part 41 (including load-bearing wheels 410 and upper rail pulleys 412) of the upper stability part 4 slides along the upper slide rail of the cabinet body 1, bearing the weight of the door body. The upper traction steel rope is wound around the upper guide wheels distributed in a triangular shape in a "ji" shape. One end is connected to the load-bearing part 41, and the other end is connected to the middle stability part 5. The tension of the steel rope is adjusted through the fixed adjustment part 73 (such as a fixed screw) to dynamically balance the traction force. The middle rail pulley of the middle stability part 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 stability part 6 slides along the lower slide rail. The lower traction steel rope is also wound around the lower guide wheels in a "ji" shape and is connected to the middle stability part 5. The three are fixed to the cabinet door through aluminum connecting columns. By using the triangularly distributed guide wheels and the "ji" shaped winding path, the gaps generated during long-term use are automatically compensated, ensuring the stable trajectory when the door body moves horizontally, reducing space occupation and improving the power transmission efficiency.

[0104] 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 stability part 5. When the door is opened, the coil spring is stretched and stores energy. The locking component 9 (including the clamping lock part 92 and the elastic spring) locks the door body through the cooperation of the clamping rod (clamping part 16) and the clamping lock block, storing kinetic energy; when the door is closed, the coil spring releases potential energy to assist the door body to close smoothly. 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.

[0105] Through the collaborative design of "multi-level stability components + ji-shaped traction ropes + power recovery", the following effects are achieved: The stability component 2 ensures that there is no shaking or deviation when the cabinet door opens and closes. The power recovery component 3 realizes kinetic energy storage and potential energy release, assisting the cabinet door to close and providing a locking function. Compared with the traditional structure, the "ji" shaped winding method optimizes the layout of the traction rope, reduces power loss, and reduces the space occupation by more than 50%; the dynamic gap compensation mechanism makes the error of the cabinet door during long-term use <0.5 mm, 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 ≤5 N; the locking component 9 realizes "one touch to lock and one touch to open", and the locking reliability reaches 99.5%. It effectively solves the problems of offset shaking, large closing resistance, and unreliable locking caused by gap accumulation in traditional sliding doors, and significantly improves the service life of the cabinet door and the user experience.
