[0033] The present application provides a sliding door.

[0034] With reference to Figures 1-6 In the embodiments of the present application, a sliding door comprises:

[0035] a door body assembly 10;

[0036] a door frame 20 provided with a sliding groove 21, a direction perpendicular to the extension direction of the sliding groove 21 being defined as a first movement direction, the door body assembly 10 being installed at the sliding groove 21 and moving along the first movement direction;

[0037] a closing structure 30 provided on the door body assembly 10, the closing structure 30 being used to drive the door body assembly 10 to move along the first direction;

[0038] A driving structure 40 is connected with the door body assembly 10, the driving structure 40 is drivingly connected with the closing structure 30, the driving structure 40 has a first driving state and a second driving state, in the first driving state, the driving structure 40 is used for driving the door body assembly 10 to separate from the door frame 20, in the second driving state, the driving structure 40 is used for driving the door body assembly 10 to abut against the door frame 20.

[0039] The utility model scheme describes a structure of sliding door, it realizes the opening and closing action of sliding door (door body assembly 10) relative to door frame (door frame 20) through a series of components. Specifically, the design includes the following parts: door body assembly 10 this is actually can open and close part, usually contain glass and frame. Door frame 20 fixed on the frame of wall body, provide sliding groove 21 for door body assembly 10 movement. Sliding groove 21 is the track in door frame 20, allow door body assembly 10 along specific direction (first movement direction, that is perpendicular to the direction of extension of sliding groove 21) sliding. Closure structure 30 is installed on door body assembly 10, for control door body assembly 10 along sliding groove 21 movement, drive structure 40 is connected to door body assembly 10 and can change state to realize the opening and closing of door body assembly 10. Drive structure 40 can be used to automatically or manually push door body assembly, make it move from first drive state to second drive state, or vice versa. It has two states: first drive state makes door body assembly 10 separate from door frame 20, at this time drive structure makes door body assembly 10 separate from door frame 20, allow door body assembly 10 to be opened. Second drive state makes door body assembly 10 abut against door frame 20, at this time drive structure makes door body assembly 10 close to door frame 20, ensure that door body assembly 10 is completely closed and keeps good sealing property. Specifically, open door body assembly 10 (from closing to opening), at this time door body assembly 10 is currently in closed state, door body assembly 10 and door frame 20 close tightly, drive structure 40 is in second drive state, ensure the good sealing between door body assembly 10 and door frame 20. User or automatic system triggers drive structure 40, make it switch from second drive state to first drive state. It can be understood that the action involving unlocking mechanism makes door body assembly 10 can begin to move. When drive structure 40 enters first drive state, it will act on closure structure 30, cause door body assembly 10 to move slightly in the direction away from door frame 20, thereby release any locking or close contact state. Once door body assembly 10 is unlocked, user or drive structure 40 itself can push door body assembly 10 along first movement direction, slide in sliding groove 21, until reach the required open position. Close door body assembly 10 (from opening to closing), to close door body assembly 10, first need to pull door body assembly 10 back to its original position along first movement direction, that is close to the side of door frame 20. This can be completed manually or automatically by drive structure 40. When door body assembly 10 approaches door frame 20, drive structure 40 should be ready to enter second drive state. At this time, closure structure 30 guides door body assembly 10 accurately back to its closed position, so that door body assembly 10 tightly close to door frame 20, realize good sealing effect. The scheme not only enhances the safety of door body assembly 10, but also improves its sealing performance under adverse weather conditions. Good sealing performance helps to reduce heat loss, especially in winter, thereby improving the energy efficiency of buildings.The tight seal can also effectively isolate external noise, providing a more quiet environment indoors.

[0040] With reference to Figures 1-6 In the embodiment of the utility model, the door body assembly 10 comprises a door body outer frame 11 and a door body 12, the door body 12 is arranged in the door body outer frame 11, the door body outer frame 11 is arranged in the door frame 20, and the door body outer frame 11 is in abutment with the door frame 20 along the first direction.

[0041] The door body assembly 10 is further subdivided into the door body outer frame 11 and the door body 12. The door body 12 is installed in the door body outer frame 11, while the door body outer frame 11 is installed in the door frame 20 and can move along the first movement direction (i.e. the direction perpendicular to the extension direction of the sliding groove 21) and eventually abut with the door frame 20. This design means that the door body outer frame 11 is the part that directly contacts the door frame 20 and realizes the sealing, while the door body 12 can be the actual door body part containing glass or other transparent materials. By arranging the door body 12 in the door body outer frame 11, the door body outer frame 11 can be replaced or repaired without affecting the door body itself, and vice versa. The door body outer frame 11, as the main part bearing the influence of the external environment, can be designed to have a stronger and more weather-resistant structure, thereby protecting the internal door body 12. The design of the door body outer frame 11 allows it to achieve tighter contact with the door frame 20, which helps to improve the sealing performance. The sealing between the door body outer frame 11 and the door frame 20, together with the sealing design of the door body 12 itself, constitutes an efficient double-layer sealing system, improving the overall air tightness and waterproof performance of the sliding door.

[0042] With reference to Figures 1-6 In the embodiment of the utility model, the door body outer frame 11 comprises a left frame 111 and a right frame 112 arranged oppositely and an upper frame 113 and a lower frame 114 arranged oppositely, the left frame 111, the right frame 112, the upper frame 113 and the lower frame 114 enclose to form the door body outer frame 11, the sliding groove 21 comprises a first sliding groove and a second sliding groove, the inner edge frame of the upper end of the door frame 20 is provided with the first sliding groove, the inner edge frame of the lower end of the door frame 20 is provided with the second sliding groove, the upper frame 113 slides in the first sliding groove, the lower frame 114 slides in the second sliding groove, the inner side of the first sliding groove and the second sliding groove is provided with a sealing element 22, and in the second driving state, the upper frame 113 and the lower frame 114 are in abutment with the sealing element 22.

[0043] The door body outer frame 11 is composed of four frames (a left frame 111, a right frame 112, an upper frame 113 and a lower frame 114), which form a rectangular structure. The door frame 20 is internally provided with two sliding grooves: a first sliding groove is located in the upper end inner frame of the door frame 20, and a second sliding groove is located in the lower end inner frame of the door frame 20. The upper frame 113 and the lower frame 114 of the door body outer frame 11 slide in the two sliding grooves respectively. In order to ensure good sealing, the inner sides of the first sliding groove and the second sliding groove are provided with sealing members 22, and the upper frame 113 and the lower frame 114 will be in close abutment with the sealing members 22 when the door body assembly 10 is closed. Specifically, when opening the door body assembly 10, the user or the automatic system triggers the driving structure 40 to switch from the second driving state to the first driving state. The driving structure 40 acts on the closing structure 30 to release the locking mechanism between the door body outer frame 11 and the door frame 20. The door body outer frame 11 slightly moves away from the door frame 20 to ensure complete unlocking. The user or the driving structure 40 pushes the door body outer frame 11 in the first movement direction, so that the upper frame 113 slides in the first sliding groove and the lower frame 114 slides in the second sliding groove until reaching the required open position. When closing the door body assembly 10, the door body outer frame 11 is pulled back to the side close to the door frame 20 in the first movement direction. When the door body outer frame 11 approaches the door frame 20, it is ensured that it accurately returns to the closed position. The driving structure 40 switches to the second driving state and applies pressure to make the door body outer frame 11 tightly fit the door frame 20, especially the abutment of the upper frame 113 and the lower frame 114 with the sealing members 22 in the first sliding groove and the second sliding groove respectively. By providing the upper and lower sliding grooves, the existence of the sliding grooves provides a clear movement path for the door body outer frame 11, ensures accurate positioning each time it is closed, enhances the reliability and safety of the door body assembly 10, and the installation of the sealing members 22 in the inner sides of each sliding groove can provide double sealing effect when the door body assembly 10 is closed, greatly improving the air tightness and waterproof performance. In the second driving state, the close abutment of the upper frame 113 and the lower frame 114 with the sealing members 22 ensures that no air or water can enter the room through the gap, improving the overall air tightness and waterproof performance of the sliding door.

[0044] Referring Figures 1-6 In the embodiment of the utility model, the driving structure 40 includes an operating handle 41 and a linkage component 42, the operating handle 41 is arranged on the left frame 111, the operating handle 41 is in transmission connection with the linkage component 42, and the linkage component 42 is in transmission connection with the closing structure 30.

[0045] The position where the operation handle 41 extends downward is defined as a first position, and the position where the operation handle 41 rotates 90° is defined as a second position. When the operation handle 41 is in the first position, the linkage component 42 is configured to drive the door assembly 10 to separate from the door frame 20. When the operation handle 41 is in the second position, the linkage component 42 is configured to drive the door assembly 10 to abut against the door frame 20.

[0046] Further, the driving structure 40 includes an operation handle 41 and a linkage component 42. The operation handle 41 is mounted on the left frame 111 of the door body outer frame 11 and is in transmission connection with the linkage component 42, and the linkage component 42 is in transmission connection with the closing structure 30. By rotating the operation handle 41, a user can control the opening and closing state of the door assembly 10. The first position is the position where the operation handle 41 extends downward, and the linkage component 42 drives the door assembly 10 to separate from the door frame 20, i.e., to open the door assembly 10. The second position is the position where the operation handle 41 rotates 90°, and the linkage component 42 drives the door assembly 10 to abut against the door frame 20, i.e., to close the door assembly 10. Specifically, to open the door assembly 10, the operation handle 41 is in the first position, and the user places the operation handle 41 in the first position extending downward. At this time, the linkage component 42 responds to the position change of the operation handle 41 and releases the locking of the door assembly 10 by the closing structure 30. The door body outer frame 11 (including the upper frame 113 and the lower frame 114) can freely move in the sliding groove 21. The user or the driving structure 40 pushes the door body outer frame 11 in the first movement direction, so that the upper frame 113 slides in the first sliding groove and the lower frame 114 slides in the second sliding groove until reaching the desired open position. To close the door assembly 10, the door body outer frame 11 is pulled back to the side close to the door frame 20 in the first movement direction. The operation handle 41 is rotated to the second position, and the user rotates the operation handle 41 by 90° to the second position. The linkage component 42 adjusts according to the new position of the operation handle 41 and drives the closing structure 30 to work, so that the upper frame 113 and the lower frame 114 of the door body outer frame 11 respectively abut against the sealing member 22 in the sliding groove, ensuring that the sliding door is completely closed and sealed well. The user only needs to complete the opening and closing of the sliding door through a simple rotating action, which reduces the complex manual operation steps and is especially suitable for frequent use scenarios. Since the linkage component 42 directly responds to the position change of the operation handle 41, the user does not need to exert excessive force to open or close the sliding door. The driving structure 40 with the operation handle 41 and the linkage component 42 not only simplifies the operation process of the user, but also significantly enhances the safety and sealing performance of the sliding door.

[0047] Reference Figures 1-6The utility model discloses an operating handle 41, left frame 111, right frame 112, closing structure 30, linkage component 42, first sliding block 422, second sliding block 423, first angle portion transmission part 424 and second angle portion transmission part 425, the utility model discloses a first transmission part and sliding portion are included to the linkage component 42, the rotation axis of first transmission part is connected with operating handle 41 rotation, the sliding portion is along left frame 111 is arranged, the sliding portion is equipped with first tooth portion, first tooth portion with first transmission part engages transmission, the both ends of sliding portion are with first sliding block 422 and second sliding block 423 sliding connection respectively, first sliding block 422 other end with first angle portion transmission part 424 swing joint, second sliding block 423 other end with second angle portion transmission part 425 swing joint, first angle portion transmission part 424 with second angle portion transmission part 425 all with closing structure 30 transmission connection.

These components work together to achieve the opening and closing action of the sliding door. The connecting member 421 is composed of a first transmission member and a sliding part. The rotation axis of the first transmission member is rotationally connected with the operating handle 41, and the sliding part is arranged along the left frame 111 and is provided with a first tooth part which is in meshing transmission with the first transmission member. The sliding part is slidably connected with the first sliding block 422 and the second sliding block 423 at two ends respectively. The other end of the first sliding block 422 is movably connected with the first corner transmission member 424. The other end of the second sliding block 423 is movably connected with the second corner transmission member 425. The first corner transmission member 424 and the second corner transmission member 425 are both in transmission connection with the closing structure 30. Specifically, when opening the door body assembly 10, the operating handle 41 is in the first position, and the user places the operating handle 41 in the first position extending downward. When the operating handle 41 rotates, it drives the first transmission member to rotate, and drives the sliding part to move along the left frame 111 through the first tooth part. The movement of the sliding part causes the first sliding block 422 and the second sliding block 423 to slide in the sliding part. The movement of the first sliding block 422 and the second sliding block 423 drives the first corner transmission member 424 and the second corner transmission member 425 to act, respectively. The first corner transmission member 424 and the second corner transmission member 425 further act on the closing structure 30, so that it switches from the closed state to the open state, i.e. releases the locking between the door body assembly 10 and the door frame 20. The door body outer frame 11 (including the upper frame 113 and the lower frame 114) can move freely in the sliding groove, and the user or the driving structure 40 pushes the door body outer frame 11 in the first movement direction to open the door body assembly 10. When closing the door body assembly 10, the door body outer frame 11 is pulled back to the side close to the door frame 20 along the first movement direction. The operating handle 41 is rotated to the second position, and the user rotates the operating handle 41 by 90° to the second position. When the operating handle 41 rotates again, it drives the first transmission member to rotate, and drives the sliding part to move along the left frame 111 through the first tooth part. The movement of the sliding part causes the first sliding block 422 and the second sliding block 423 to slide reversely in the sliding part. The movement of the first sliding block 422 and the second sliding block 423 drives the first corner transmission member 424 and the second corner transmission member 425 to act, respectively. The first corner transmission member 424 and the second corner transmission member 425 further act on the closing structure 30, so that it switches from the open state to the closed state, i.e. drives the door body outer frame 11 to tightly fit with the door frame 20, to ensure that the sliding door is completely closed and sealed well. It can be understood that the first corner transmission member 424 and the second corner transmission member 425 can be designed to contain springs, connecting rods or other forms of mechanical connection.

The mounting member 31 is in transmission connection with one of a first corner transmission member 424 or a second corner transmission member 425, so that when the handle 41 is rotated, the mounting member 31 is driven to move in a first direction by the action of the connecting member 42, and the locking member 32 is moved along the sliding groove, thereby realizing the opening and closing action of the door body assembly 10. Specifically, when the closing lock is locked, the reverse movement of the first sliding block 422 and the second sliding block 423 causes the first corner transmission member 424 or the second corner transmission member 425 to also adjust the position in the opposite direction, thereby driving the mounting member 31 to move in the opposite first direction. The movement of the mounting member 31 causes the locking member 32 to slide along the sliding groove, re-establishing close contact with the door frame 20 and locking, ensuring that the door body assembly 10 is completely closed and sealed well. When the closing lock is unlocked, the first corner transmission member 424 or the second corner transmission member 425 adjusts the position according to the movement of the mounting member, thereby driving the mounting member 31 to move in the first direction. The movement of the mounting member 31 causes the locking member 32 to slide along the sliding groove (such as the first sliding groove or the second sliding groove), thereby releasing the locking state between the locking member 32 and the door frame 20. The door body outer frame 11 (including the upper frame 113 and the lower frame 114) can be freely moved in the sliding groove, and the user or the driving structure 40 pushes the door body outer frame 11 in the first movement direction to open the door body assembly 10. When the door body assembly 10 is closed, the locking member 32 can ensure that the door body outer frame 11 closely fits the door frame 20, providing better sealing effect and reducing air or water leakage. In combination with the sealing member 22 in the sliding groove, double sealing is realized, enhancing the safety and air tightness of the sliding door. The cooperation of the mounting member 31 and the locking member 32 makes the opening and closing process of the sliding door smoother, reduces the jamming or resistance, and improves the user's experience.

[0051] Referring to Figures 1-6 In the embodiment of the utility model, the locking member 32 comprises a guide part and a second transmission member, the guide part is provided with a second tooth part arranged along the first direction, the outer peripheral wall of the second transmission member is provided with a third tooth part, the second tooth part and the third tooth part are in meshing connection, the second transmission member has a protrusion matched with the sliding groove, and the protrusion is slidingly arranged in the sliding groove.

[0052] The first corner transmission member 424 or the second corner transmission member 425 adjusts the position according to the movement of the mounting member, thereby driving the mounting member 31 to move in the first direction. The movement of the mounting member 31 causes the protrusion of the second transmission member to slide along the sliding groove (such as the first sliding groove or the second sliding groove). Due to the meshing of the second tooth portion and the third tooth portion, the second transmission member rotates with the movement of the mounting member 31, thereby moving the protrusion along the sliding groove and releasing the locking state between the protrusion and the door frame 20. The door body outer frame 11 (including the upper frame 113 and the lower frame 114) can be freely moved in the sliding groove, and the user or the driving structure 40 pushes the door body outer frame 11 in the first movement direction to open the door body assembly 10. Through the meshing transmission of the gears (the second tooth portion and the third tooth portion), the sliding portion and the second transmission member can be accurately controlled, ensuring accurate operation each time. When the door body assembly 10 is closed, the protrusion of the second transmission member can ensure that the door body outer frame 11 is tightly fitted with the door frame 20, providing better sealing effect and reducing air or water leakage. Combined with the sealing member 22 in the sliding groove, double sealing is achieved, enhancing the safety and air tightness of the sliding door.

[0053] With reference to Figures 1-6 In the embodiment of the utility model, the outer peripheral wall of the second transmission member has a first transmission region and a first non-transmission region arranged circumferentially, and the first transmission region is provided with a plurality of third tooth portions arranged circumferentially.

[0054] By arranging the first transmission region and the first non-transmission region on the outer peripheral wall of the second transmission member, the rotation angle and position of the second transmission member can be more accurately controlled, ensuring accurate operation each time. It can be understood that the design of the first transmission region and the first non-transmission region allows the second transmission member to perform different tasks in different states. For example, in some states, the second transmission member only needs to slide without rotating; while in other states, it needs to rotate to complete the locking or unlocking action.

[0055] With reference to Figures 1-6 In the embodiment of the utility model, the sliding door further comprises a stop structure 50, the stop structure 50 comprises a limiting member 51 and a stop member 52, the limiting member 51 is arranged on the left frame 111, and the stop member 52 is arranged on at least one of the first sliding block 422 and the second sliding block 423, the limiting member 51 is constructed with an arc-shaped guide groove, and the stop member 52 has a guide block matched with the arc-shaped guide groove.

[0056] The limiting piece 51 is installed on the left frame 111 and is configured with an arc-shaped guide groove. The stop piece 52 is provided at least on one of the first sliding block 422 or the second sliding block 423 and is provided with a guide block matched with the arc-shaped guide groove. When the operating handle 41 is rotated, the movement of the connecting component 42 can drive the mounting piece (the first sliding block 422 or the second sliding block 423) to move in a first direction, and the guide block of the stop piece 52 moves in the arc-shaped guide groove of the limiting piece 51, thereby realizing the opening and closing of the door body assembly 10. At the same time, the stop structure 50 ensures that the movement path of the mounting piece is stable and controllable, avoiding accidental jamming or deviation. It can be understood that the limiting piece 51 is configured as an arc-shaped guide rail fixed on the left frame 111. The stop piece 52 includes a mounting piece matched with the arc-shaped guide rail and provided with a guide block; or the limiting piece 51 is configured as a fixed piece with an arc-shaped guide groove and is located on the left frame 111. The stop piece 52 includes a mounting piece provided with a gear, the gear is engaged with a rack in the arc-shaped guide groove, and the mounting piece is provided with a guide block. It can be understood that the guide block can be a ball guide block, the ball is embedded in the guide block and in contact with the arc-shaped guide groove; or the guide block is a T-shaped guide block, the cross section of the guide block is T-shaped, the bottom wide part is embedded in the arc-shaped guide groove, and the top narrow part is used for connecting the mounting piece or other components.
