The damping guide assembly 30 comprises a protection piece 31 radially sliding along the other side of the shell 10, and a pushing piece 32 movably arranged inside the protection piece 31.

[0030] In the above embodiment, the main advantages are to improve the protection of the pushing piece 32 and reduce the excessive direct contact with the shell cover 11. Secondly, it can provide smooth buffering effect and damping control, making the opening and closing process of the sliding door more smooth and natural. Finally, it can increase the service life of the damper and reduce the damage caused by environmental factors.

[0031] Specifically, the damping kit for door and window displacement adopts a double-shell structure, and the shell 10 is internally provided with the expansion damping piece 20 and the damping guide assembly 30. The expansion damping piece 20 is located at one side of the shell 10, which is used to provide the buffering effect and damping control of the sliding door. The damping guide assembly 30 is located at the other side of the shell 10, which is used to guide and limit the displacement of the expansion damping piece 20. The damping guide assembly 30 comprises the protection piece 31 and the pushing piece 32. The protection piece 31 radially slides along the other side of the shell 10, which can guide the movement direction of the expansion damping piece 20. The pushing piece 32 is located inside the protection piece 31 and is movably arranged in the protection piece 31. The protection piece 31 can not only guide the movement direction, but also not hinder the rotation of the pushing piece 32, further protecting the pushing piece 32 and reducing the excessive direct contact with the shell cover 11. The position of the pushing piece 32 can be adjusted according to actual needs, so that the damping kit for door and window displacement achieves the ideal buffering effect and damping control.

[0032] In some embodiments, the protection piece 31 is internally provided with a U-shaped groove 311 away from the expansion damping piece 20, and the outer side of the pushing piece 32 is adapted in the U-shaped groove 311. The connection between the expansion damping piece 20 and the damping guide assembly 30 is unstable, which may cause the damper to fail or reduce the effect. The positioning of the pushing piece 32 inside the damping guide assembly 30 is not firm enough, which may cause the position to deviate or be not firmly locked. Therefore, in this scheme, a stable connection mode is provided to ensure the good cooperation and movement effect of the expansion damping piece 20 and the damping guide assembly 30, and the positioning performance of the pushing piece 32 inside the damping guide assembly 30 is enhanced to ensure its accurate position and firm locking during movement.

[0033] In the damping guide assembly 30 of the door and window displacement damping kit, the protection piece 31 is internally provided with a U-shaped groove 311 away from the telescopic damping piece 20. The outer side of the push piece 32 is adapted in the U-shaped groove 311, and through the design of the groove, the movable cooperation between the protection piece 31 and the push piece 32 is realized. The design of the U-shaped groove 311 can ensure the stable connection between the protection piece 31 and the push piece 32, and realize flexible action in the process of opening and closing the sliding door. The position of the push piece 32 is adapted in the U-shaped groove 311, so that it is accurately positioned and can be locked in the appropriate position, ensuring the normal movement and function of the damping guide assembly 30. Through this design, the connection and positioning problems of the door and window displacement damping kit are effectively solved, the performance and reliability of the damper are improved, and the stable opening and closing and damping control effect of the sliding door are ensured.

[0034] In the embodiment, due to the movement of the damping guide assembly 30, the protection piece 31 and the push piece 32 may be separated or moved, resulting in poor connection stability and positioning accuracy between the protection piece 31 and the push piece 32. The U-shaped groove 311 is internally provided with a protrusion 312 away from the telescopic damping piece 20, and the outer side of the push piece 32 is provided with a recess 321 that can move and rotate on the protrusion 312. In the embodiment, the connection between the protection piece 31 and the push piece 32 is more stable and reliable, the durability and service life of the damping guide assembly 30 are increased, the positioning accuracy and stability of the damping guide assembly 30 are enhanced, and the correct positioning and movement control of the protection piece 31 and the push piece 32 are ensured.

[0035] The specific implementation method is as follows: through the cooperation of the protrusion and the recess 321, the connection between the protection piece 31 and the push piece 32 is more stable and reliable. The protrusion provides a fixing and supporting function, and the recess 321 provides a freedom of movement and rotation. This design enables the protection piece 31 and the push piece 32 to maintain the correct position and posture during movement, while having certain flexibility and controllability. The implementation of the technical scheme further enhances the durability, connection stability and positioning accuracy of the damping guide assembly 30, effectively solves the problems of looseness, separation or position deviation that may occur during movement, and ensures the normal operation and stable and reliable damping effect of the door and window displacement damping kit.

[0036] In a further embodiment, the toggle piece 32 is provided with a guide block 322 on each side of the end portion away from the protection piece 31, and the protection piece 31 is provided with a guide rib 313 on each side, each guide block 322 and each guide rib 313 are correspondingly arranged on the same side, and a slide channel 111 is formed on one side of the two housings 10 to allow the guide rib 313 and the guide block 322 to slide radially inside the housing 10. This technical solution solves the problem of stable guidance and alignment between the protection piece 31 and the toggle piece 32, ensuring accurate cooperation and movement between them. During the opening and closing of the sliding door, the housing 10 is subjected to force, which may cause the relative position of the protection piece 31 and the toggle piece 32 to change. The implementation of this technical solution has the following technical effects: providing stable and accurate guidance and alignment, ensuring correct cooperation and movement control between the protection piece 31 and the toggle piece 32. Strengthening the stability of the housing 10 structure and the relative position of the protection piece 31 and the toggle piece 32, resisting external force, and maintaining stable movement performance.

[0037] The specific implementation method is that the guide block 322 and the guide rib 313 correspond on the same side and are connected through the slide channel 111. The slide channel 111 slides along the radial direction inside the housing 10 to maintain the sliding and alignment between the guide rib 313 and the guide block 322. The guide block 322 provides the guidance function of the toggle piece 32, ensuring the accuracy and stability of its movement. The guide rib 313 serves as the support and regular movement guide of the protection piece 31, ensuring the cooperation and alignment between the protection piece 31 and the toggle piece 32. The arrangement of the slide channel 111 allows the guide rib 313 and the guide block 322 to slide along the radial direction inside the housing 10 to adapt to the changes during the opening and closing of the sliding door. Through the above structure and design, this technical solution can realize the stable guidance and alignment between the protection piece 31 and the toggle piece 32, and enhance the movement control and stability of the damping guide assembly 30. The design of the slide channel 111 of the housing 10 provides a sliding space for the guide rib 313 and the guide block 322, ensuring their correct position and relative stability during the opening and closing of the sliding door. This ensures smooth movement of the damping sleeve of the door and window displacement, effective damping control, and good durability and service life.

[0038] In some embodiments, the two shell covers 11 are provided with active cutouts 112 on both sides to accommodate the rotation of the guide blocks 322 of the actuating member 32. According to further description, the two shell covers 11 are provided with active cutouts 112 on both sides to accommodate the rotation of the guide blocks 322 of the actuating member 32. The cutouts allow the guide blocks 322 to rotate freely and coordinate with the actuating member 32. Through the design of the active cutouts 112, the guide blocks 322 can rotate freely on the shell covers 11. The actuating member 32 is fitted in the active cutouts 112 and coordinates with the rotational movement of the guide blocks 322. In this way, the shell covers 11 and the actuating member 32 can maintain stable cooperation and achieve good motion control and coordinated movement. This design reduces direct contact between the actuating member 32 and the shell covers 11, avoiding possible collisions and friction. This helps to reduce the wear and tear of the damper during the opening and closing of the sliding door, improving the service life and reliability of the damper. Through the above structure and design, the technical solution realizes the coordinated movement and cooperation between the shell covers 11 and the actuating member 32, reduces collisions and friction, and improves the stability and durability of the damper.

[0039] The above embodiments solve the problem of coordinated cooperation and motion control between the shell covers 11 and the actuating member 32. It solves the technical problem that the actuating member 32 may collide or rub with the shell covers 11 during the opening and closing of the sliding door, affecting the normal operation of the damper. The implementation of this technical solution has the effect of providing coordinated movement and cooperation between the shell covers 11 and the actuating member 32, increasing the stability and accuracy of motion control of the damper. Reducing the collisions and friction between the actuating member 32 and the shell covers 11 reduces the wear and tear that may be caused to the damper.

[0040] In further embodiments, the protective member 31 has a slope on the side away from the telescopic damper 20 to compensate for the rotation action space of the guide blocks 322 of the actuating member 32. This technical solution provides coordinated cooperation and motion control between the protective member 31 and the actuating member 32, increasing the stability and action accuracy of the damper; it expands the rotation action space of the actuating member 32, making it more flexible to adapt to the opening and closing movement of the sliding door.

[0041] The inclined surface provides an operational range for the compensation knob 32 to rotate. Through the design of the inclined surface, the coordinated movement between the protection piece 31 and the compensation knob 32 is achieved. The inclined surface provides space for the compensation knob 32 to rotate, allowing it to freely rotate. In this way, the movement control and precision of the damper are improved. This design expands the rotation action space of the compensation knob 32. It makes the compensation knob 32 more flexible to adapt to the opening and closing movement of the sliding door, ensuring its normal work and adapting to various opening angles and scene requirements. Through the above structure and design, the technical scheme realizes the coordinated movement and alignment between the protection piece 31 and the compensation knob 32, provides a larger rotation action space, and increases the stability and action control precision of the damper. Specifically, it solves the problem of coordinated movement and alignment between the protection piece 31 and the compensation knob 32; during the opening and closing process of the sliding door, the compensation knob 32 may be restricted and cannot fully exert its movement ability.

[0042] In the above embodiment, the shell 11 is provided with an active cutout 112 for the active rotation of the guide block 322 of the knob 32. In this further description, the active cutout 112 is obliquely arranged at one-third of the slide 111 and is in communication with the outside. The two technical solutions are related in that they both involve the cooperation and movement control between the shell 11 and the knob 32. Among them, the technical solution in the previous question provides stable cooperation and coordinated movement, while the technical solution in this further description provides an obliquely arranged active cutout 112 and the characteristics of the active cutout 112 relationship.

[0043] The two technical solutions together solve the following technical problems: the coordinated movement and alignment between the shell 11 and the knob 32. During the opening and closing process of the sliding door, the knob 32 may collide or rub with the shell 11, affecting the normal operation of the damper. The specific implementation method is as follows: the active cutout 112 is obliquely arranged at one-third of the slide 111 and is in communication with the outside. The purpose of this design is to achieve the coordinated movement and avoid collision between the knob 32 and the shell 11. The oblique arrangement of the active cutout 112 allows the knob 32 to slide more smoothly during movement and better cooperate with the shape of the shell 11. At the same time, the communication with the outside can reduce the collision and friction between the knob 32 and the shell 11, reducing potential wear and tear. Through the above structure and design, the two related technical solutions together solve the problem of coordinated movement and alignment between the shell 11 and the knob 32, avoid collision and friction, and improve the stability and durability of the damper. At the same time, it realizes more stable movement and precise damping control effect during the opening and closing process of the sliding door.

[0044] In some embodiments, the actuator 32 and the same side of the movable cutout 112 are provided with a U-shaped actuator opening 323 adapted to the sliding door actuator. By introducing the U-shaped actuator opening 323, the technical solution provides an adaptive interface between the actuator 32 and the sliding door actuator, realizing their stable connection. This can enhance the positioning and control of the actuator 32 in the movable cutout 112, improve the accuracy and stability of movement. Overall, this innovation optimizes the cooperation and movement control between the actuator 32 and the shell 11, further improving the performance and reliability of the damper.

[0045] In some embodiments, T-shaped grooves 324 are provided inside the U-shaped actuator opening 323 on both sides, and elastic I-shaped blocks 325 are provided to reduce actuator wear and adapt to the T-shaped grooves 324. The actual innovation of this technical solution lies in the introduction of the design of T-shaped grooves 324 and elastic I-shaped blocks 325, which are used to reduce wear between the actuator 32 and the U-shaped actuator opening 323, and improve the service life and reliability of the actuator.

[0046] The shape of the I-shaped groove has a nesting effect. The elastic I-shaped block 325 that adapts to the T-shaped groove 324 is filled in the T-shaped groove 324 and is adapted to the shape of the T-shaped groove 324. When the actuator 32 cooperates with the U-shaped actuator opening 323, the elastic I-shaped block 325 is filled in the T-shaped groove 324, which plays a buffering and wear-reducing role. The elastic I-shaped block 325 has certain elastic properties, which can absorb shocks and vibrations during movement, while reducing direct contact between the actuator 32 and the U-shaped actuator opening 323, reducing the degree of wear. In summary, this technical solution reduces wear between the actuator 32 and the U-shaped actuator opening 323 through the design of T-shaped grooves 324 and elastic I-shaped blocks 325, improves the service life and stability of the actuator, and further increases the reliability and performance consistency of the damper.

[0047] In further embodiments, the piston end of the telescopic damper 20 is threadedly connected to the end of the protective member 31 away from the actuator 32. Threaded connection facilitates the disassembly and replacement of the piston end of the telescopic damper 20 and the protective member 31. When maintenance or replacement is required, the operation can be performed by tightening or loosening the threaded connection, which is convenient and fast. Threaded connection can ensure the firm connection between the piston end and the protective member 31, avoiding accidental loosening or falling off, and improving the stability and safety of the entire damper.

[0048] The telescopic damper 20 is a hydraulic damper, an air damper, a magnetic damper, and a spring damper, which means that the telescopic damper 20 can adopt any type of hydraulic damper, air damper, magnetic damper, or spring damper.

[0049] Briefly describe different types of dampers: hydraulic dampers, hydraulic dampers control the damping speed of movement by the resistance of liquid flowing in the damping chamber. It usually includes a piston and a damping cylinder, the flow of liquid through the adjustment of damping valve or adjusting device to achieve the desired damping effect.
