Description

Technical Field

[0001] This invention relates to the field of sliding door technology, specifically to a movable sliding door. Background Technology

[0002] Sliding doors are a type of door that opens and closes by pushing or pulling, and can slide left and right on a track to save space. During opening and closing, sliding doors rely on a sliding track system for smooth movement and accurate positioning. Common sliding doors mainly use a double-track or single-track structure. In a double-track design, the upper and lower edges of the sliding door are embedded or fitted with the upper and lower tracks respectively. This design is suitable for taller and heavier sliding doors, ensuring smooth and consistent movement over long-term use. A single-track design typically only has a main load-bearing track at the bottom, with only a simple guide bar or limiter at the top, or conversely, the upper track is the main suspension load-bearing track, with only an auxiliary guide at the bottom. Single-track sliding doors have a relatively simple structure and are easier to install.

[0003] However, in actual use, the installation precision of double-track sliding doors is extremely strict. When the two tracks are not perfectly parallel or when the tracks are offset from the door opening plane, it can easily cause the sliding door to jam, producing abnormal noise or causing additional wear on the tracks. Single-track sliding doors, after prolonged use, may experience slight sagging or tilting, affecting the overall sealing and smoothness of movement. Single-track sliding doors offer weaker constraint on the door leaf, making them prone to wobbling or derailment under external force or frequent pushing. Furthermore, regardless of whether it's a double-track or single-track sliding door, the door's movement is strictly limited to the entire length of the track; the door cannot move beyond the track endpoints, thus failing to achieve concealment. Summary of the Invention

[0004] The present invention was made to solve the above-mentioned technical problems, and its purpose is to provide a movable sliding door. By setting the sliding component in the middle of the sliding door, the sliding door's movement distance is not limited to the end of the slide rail, thus expanding the sliding door's movement distance.

[0005] To achieve the above objectives, the present invention provides a movable sliding door, installed on a building wall, including a door body; a sliding assembly, at least two sets of which are installed in the middle of the movable sliding door, including a slide rail and a slider, wherein the slide rail is installed on the building wall and the slider is installed on the door body; and a drive assembly, including a drive motor, a rotating gear and a rack, wherein the drive motor is connected to the rotating gear and the rack is installed on the door body, and the rack meshes with the rotating gear.

[0006] Preferably, the door body includes a first door and a second door, which are arranged opposite to each other.

[0007] Preferably, the first door body and the second door body have accommodating grooves formed on opposite sides, and a first sealing element is provided in the accommodating groove.

[0008] Preferably, it further includes a door gap latch connected to the first door body and the second door body, wherein the first door body and the second door body are respectively provided with connecting holes on opposite sides, and the door gap latch is connected to the connecting holes.

[0009] Preferably, a second sealing element is provided on the side of the door body facing the building wall.

[0010] Preferably, the door body further includes a latch, and the building wall includes a latch hole, the latch being inserted into the latch hole to fix the door body to the building wall.

[0011] Preferably, it further includes a locking device connected to the pin.

[0012] Based on the above description and practice, the movable sliding door of this invention, installed on a building wall, includes a door body, a sliding assembly, and a drive assembly. The drive assembly drives the door body to move along the sliding assembly, realizing the opening and closing of the movable sliding door. At least two sets of sliding assemblies are provided, installed in the middle of the movable sliding door, ensuring that the movable sliding door always moves along the direction of the sliding assembly during movement. The sliding assembly includes a slide rail and a slider. The slide rail is installed on the building wall, and the slider is installed on the door body, slidingly mounted on the slide rail. By providing multiple sets of sliding assemblies, even if the slider accidentally falls off the slide rail during movement, the other sliding assemblies can still provide guidance, and the entire movable sliding door can be used normally. The drive assembly includes a drive motor, a rotating gear, and a rack. The drive motor is connected to the rotating gear, and the rack is installed on the door body. The rack meshes with the rotating gear, and the drive motor drives the rotating gear to rotate, meshing with the rack and thus moving the door body. Furthermore, by cooperating with the rotating gears and racks, the entire moving sliding door's path can be determined according to the rack's length, with the slide rail only serving a positioning and guiding function. This further enables the moving sliding door to move a distance beyond the slide rail's length, extending its movement path and expanding its application scenarios. Attached Figure Description

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] This invention discloses a movable sliding door; please refer to [the relevant documentation]. Figures 1 to 7The sliding door includes a door body 1, a sliding assembly 2, and a drive assembly 3, all installed on a building wall 10. The drive assembly 3 drives the door body 1 to move along the sliding assembly 2, thus opening and closing the sliding door. At least two sets of sliding assemblies 2 are provided, installed in the middle of the sliding door, ensuring that the sliding door always moves along the direction of the sliding assembly 2 during movement. The sliding assembly 2 includes a track 21 and a slider 22. The track 21 is installed on the building wall 10, and the slider 22 is installed on the door body 1, slidingly mounted on the track 21. By providing multiple sets of sliding assemblies 2, even if the slider 22 accidentally falls off the track 21 during movement, the other sliding assemblies 2 can still provide guidance, allowing the entire sliding door to function normally. The drive assembly 3 includes a drive motor 31, a rotating gear 32, and a rack 33. The drive motor 31 is connected to the rotating gear 32, and the rack 33 is mounted on the door body 1. The rack 33 meshes with the rotating gear 32. The drive motor 31 drives the rotating gear 32 to rotate, which in turn meshes with the rack 33, thus moving the door body 1. Furthermore, through the cooperation of the rotating gear 32 and the rack 33, the entire travel path of the sliding door can be determined according to the length of the rack 33. The slide rail 21 only serves as a positioning guide, further enabling the sliding door to move a distance beyond the length of the slide rail, extending the movement path of the sliding door and expanding its application scenarios.

[0025] Understandably, to prevent vertical vibration or jumping of the sliding door when it moves along the sliding assembly 2, in some embodiments, the sliding door also includes a limiting assembly 4. The limiting assembly 4 is installed above the sliding assembly 2 and can exert a certain force on the slide rail 21 to prevent the sliding door from vibrating or jumping under the action of external forces during the opening and closing process, which would cause the slider 22 to fall off the slide rail 21 and affect the smooth use of the sliding door.

[0026] To ensure the overall strength of the sliding door, in some embodiments, the door body 1 further includes a support frame 11 and a filling material layer 12. The filling material layer 12 is located within the support frame 11, which covers the entire door body 1, thus strengthening the overall strength and rigidity of the sliding door and preventing deformation under external forces or wind pressure during use. The sliding assembly 2 and the drive assembly 3 are installed on the support frame 11, further strengthening the connection between the sliding assembly 2 and the drive assembly 3 and the door body 1.

[0027] Understandably, in some embodiments, the filling material layer 12 includes a thermal insulation layer and a sound insulation layer, which ensures the thermal insulation and sound insulation effect inside the door body 1, and further improves the usability of the sliding door.

[0028] Furthermore, sliding doors are typically designed with two doors, increasing the opening area while maintaining the strength of each door panel. In some embodiments, the door body 1 includes a first door panel 13 and a second door panel 14, which are arranged opposite to each other. When the sliding door is opened, its entrance can be fully opened, facilitating the passage of large items and allowing for quick passage of a large number of people. When the first door panel 13 and the second door panel 14 are fully open, a more open sense of space is created, enhancing the user experience. Simultaneously, by having the first door panel 13 and the second door panel 14, if one door panel malfunctions, the other door panel can still be used to allow items and people to enter and exit. Moreover, the complementary arrangement of the opposite sides of the first door panel 13 and the second door panel 14 ensures a stable interlocking fit while also guaranteeing the airtightness of the sliding door when closed.

[0029] Understandably, in order to achieve a sealing effect for the sliding door, in some embodiments, receiving grooves 15 are formed on opposite sides of the first door body 13 and the second door body 14, and a first sealing element 16 is provided in the receiving groove 15. When the first door body 13 and the second door body 14 are closed together, the closing noise is reduced and the sealing between the first door body 13 and the second door body 14 is strengthened, which can also achieve noise reduction and heat preservation effects on the inside and outside of the sliding door. In addition, the setting of the first sealing element 16 can also strengthen the friction between the first door body 13 and the second door body 14, preventing the sliding door from being easily opened under the action of external wind or other factors, thus ensuring its tightness.

[0030] Understandably, in some embodiments, door gap sealing strips 7 are also provided on the opposite sides of the first door body 13 and the second door body 14. When the first door body 13 and the second door body 14 are closed, the door gap sealing strips 7 on both sides are staggered, which further ensures the sealing performance of the sliding door while improving the sound insulation and heat preservation effect of the sliding door.

[0031] To ensure the stability of the first door 13 and the second door 14 when closed, in some embodiments, the sliding door further includes a door gap latch 5. The door gap latch 5 is connected to the first door 13 and the second door 14. Corresponding connecting holes 17 are provided on opposite sides of the first door 13 and the second door 14, and the door gap latch 519 is connected to the connecting holes 17. When the sliding door is closed, the first door 13 and the second door 14 are fitted together. By using the door gap latch 519 to pass through the connecting holes 17 on the first door 13 and the second door 14, the first door 13 and the second door 14 are fixed, ensuring the sealing effect of the entire sliding door when closed, and preventing the first door 13 and the second door 14 from moving under the action of external force when closed, thus preventing the sliding door from opening.

[0032] Furthermore, in some embodiments, a second seal 18 is provided on the side of the door body 1 facing the building wall 10. The second seal 18 can fill and seal the space between the building wall 10 and the door body 1 to prevent noise or low temperature from leaking out between the door body 1 and the building wall 10, thus affecting the sound insulation and heat preservation effect of the entire sliding door.

[0033] Understandably, the sliding door can also be opened only a certain distance and then stopped stably when it does not need to be fully opened. In some embodiments, the door body 1 also includes a latch 19, and the building wall 10 includes a door pin hole 101. The latch 19 can be inserted into the door pin hole 101 to fix the door body 1 to the building wall 10. Multiple door pin holes 101 can be provided along the horizontal direction of the door body 1. When the door body 1 moves a certain distance but is not fully opened, the latch 19 can be inserted into the corresponding door pin hole 101 to fix the door body 1, preventing the sliding door from easily shaking when subjected to external force when it moves to the corresponding position, thus affecting the usability of the sliding door.

[0034] Furthermore, the sliding door also includes a locking device 6, which is connected to the bolt 19. When the door body 1 moves along the slide rail 21 to a specific position, the locking device 6 is activated, pushing the bolt 19 into the door pin hole 101, thus fixing the door body 1 and preventing the sliding door from shaking under external force after opening. The locking device 6 can be connected to an external control system. A sensor is installed near each door pin hole 101, and the sensor is also connected to the control system, enabling the locking device 6 to automatically open and insert the bolt 19 into the door pin hole 101. The connection method and control method between the control system, sensors, and locking device 6 are all existing technologies, and those skilled in the art can implement this control using existing devices, so they will not be described in detail here. In addition, the locking device 6 may also include an elastic element and a locking block. The locking block compresses the elastic element to cause it to deform, and the elastic element is connected to the bolt 19. After the door body 1 reaches the corresponding position, the user can release the locking block, causing the elastic element to return to its original shape and push the bolt 19 into the door bolt hole 101, thereby manually locking the door body 1.

[0035] Since the sliding door is driven by the drive assembly 3 to move the door body 1 along the sliding assembly 2, and the sliding assembly 2 is located in the middle of the door body 1, the movement of the door body 1 no longer requires the upper and lower sliding rails 21. Therefore, in some embodiments, the sliding door can be composed of multiple sets of door bodies 1, sliding assemblies 2, and drive assemblies 3 arranged sequentially along the direction of gravity, and multiple sets of door bodies 1 can be closed simultaneously (e.g., Figure 7 -a), open simultaneously (e.g.) Figure 7 -b) or partially open (e.g.)Figure 7 -c), and each door body 1 can move a distance beyond the length of the slide rail 21, making the movable sliding door have a larger opening area and more suitable for various usage scenarios.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
