[0027] The utility model will be further explained in connection with the drawings and embodiment:

[0028] Embodiment 1

[0029] Referring to Figures 1 to 3As shown, the embodiment discloses a sliding door, which comprises a frame 11 and a movable door 12 movably arranged on the frame 11, and an electric moving mechanism 3 for driving the movable door 12 to move back and forth, wherein the electric moving mechanism 3 comprises a gear member 31, a power assembly 33 for driving the gear member 31 to rotate, and a movable rack 32 for intermeshing with the gear member 31, the gear member 31 and the power assembly 33 are arranged on the frame 11, the movable rack 32 is arranged on the movable door 12, and the movable rack 32 is arranged in a horizontal direction,

[0030] The gear member 31 is connected with a first clutch member 34, the power assembly 33 is provided with a second clutch member 331 which can be separated from or engaged with the first clutch member 34, and the power assembly 33 is connected with a clutch driving assembly 35 for driving the power assembly 33 to move in a direction close to or away from the first clutch member 34.

[0031] In use, the gear member 31 and the power assembly 33 are arranged on the frame 11, and the movable rack 32 is arranged on the movable door 12. When it is needed to drive the movable door 12 to move by electricity to adjust the opening degree of the movable door 12, the clutch driving assembly 35 drives the second clutch member 331 on the power assembly 33 to move in a direction close to the first clutch member 34 until the second clutch member 331 is engaged with the first clutch member 34, and then the power assembly 33 is engaged with the gear member 31 through the clutch structure composed of the first clutch member 34 and the second clutch member 331, and then the power assembly 33 drives the gear member 31 to rotate, and drives the movable rack 32 intermeshing with the gear member 31 to move in a horizontal direction, so as to realize the opening and closing of the movable door 12. When it is needed to convert the movable door 12 to be manually driven to move, the second clutch member 331 on the power assembly 33 is driven by the clutch driving assembly 35 to move away from the first clutch member 34, so that the power assembly 33 is separated from the gear member 31, and then the electric moving mechanism 3 can be avoided to interfere with the manual driving of the movable door 12, and then the user can manually drive the movable door 12 to move.

[0032] In this embodiment, a gear 31 and a movable rack 32 meshing with each other are provided between the frame 11 and the movable door 12. A first clutch 34 and a second clutch 331 that can approach or engage with each other are provided between the power assembly 33 and the gear 31. A clutch drive assembly 35, which can drive the power assembly 33 to move towards or away from the first clutch 34, is also provided. When the movable door 12 needs to be pushed or pulled electrically, the clutch drive assembly 35 can drive the second clutch 331 to approach and engage with the first clutch 34. The power can then be transmitted to the gear component 31 to realize the electric push-pull sliding door 12. When it is necessary to push or pull the sliding door 12 manually, the clutch drive component 35 can drive the second clutch component 331 away from the first clutch component 34, and the power component 33 can be disconnected from the gear component 31. The user can then push or pull the sliding door 12 manually. The user can choose to push or pull the sliding door 12 electrically or manually according to their needs. The switching between the two modes of electric push-pull operation and manual push-pull operation of the sliding door 12 is simple and quick, and the sliding door is more flexible.

[0033] The gear component 31 and the first clutch component 34 can be integrally formed and rotatably mounted on the frame 11 via a bearing seat, or they can be connected by two independent components.

[0034] In some embodiments, a guide rod is provided at the axis of the first clutch 34, and a guide sleeve is provided at the axis of the second clutch 331. The guide rod is slidably disposed in the guide sleeve to increase the stability of the movement of the second clutch 331.

[0035] In some embodiments, see Figure 3 As shown, the first clutch 34 and the second clutch 331 have intermeshing ring teeth on their opposite end faces, and the first clutch 34, the second clutch 331 and the gear 31 are arranged along the same axial direction.

[0036] By providing meshing annular teeth on the first clutch 34 and the second clutch 331, the first clutch 34 and the second clutch 331 can engage with each other when they approach each other, forming a joint action in the circumferential direction to transmit the power of the power assembly 33. At the same time, the second clutch 331 can smoothly disengage from the first clutch 34 when it moves away from the first clutch 34, breaking the transmission connection between the power assembly 33 and the gear 31. The overall structure of the clutch structure composed of the first clutch 34 and the second clutch 331 is simpler and easier to manufacture.

[0037] In some embodiments, see Figure 3 As shown, the power assembly 33 includes a drive motor 332, and the output shaft of the drive motor 332 is connected to the second clutch 331.

[0038] When the first clutch 34 and the second clutch 331 are engaged with each other, the transmission motor 332 rotates to drive the second clutch 331 to rotate, which in turn drives the gear 31 connected with the first clutch 34 to rotate, and further drives the movable rack 32 to move in the horizontal direction, thereby driving the movable door 12 to move.

[0039] In some embodiments, referring to Figure 3 As shown, the clutch driving assembly 35 comprises a base 351, and the base 351 is provided with a transmission rod 352, which is parallel to the axis direction of the gear 31. The transmission rod 352 is provided with a sliding piece 354 which is connected with the transmission motor 332.

[0040] In the first embodiment, the transmission rod 352 is a threaded rod, and the sliding piece 354 is driven to reciprocate along the transmission rod 352 by rotating the transmission rod 352, which in turn drives the second clutch 331 of the transmission motor 332 to approach or move away from the first clutch 34, thereby changing the connection relationship between the power assembly 33 and the gear 31, and further quickly completing the switching between the electrically-driven push-pull operation and the manually-driven push-pull operation of the movable door 12.

[0041] In the second embodiment, referring to Figure 3 As shown, the sliding piece 354 is provided with a cavity, and the cavity is provided with a spiral elastic deformation piece 355. One end of the elastic deformation piece 355 is connected with the sliding piece 354, and the elastic deformation piece 355 is spirally wound outside the side wall of the transmission rod 352 and is arranged in opposite rotation with the transmission rod 352. The side wall of the transmission rod 352 is provided with a limiting protruding column 353, and the transmission rod 352 is connected with a clutch driving motor 356 for driving the transmission rod 352 to rotate.

[0042] In use, the clutch driving motor 356 is started to drive the transmission rod 352 to rotate forward or reverse, which in turn drives the limiting protruding column 353 to rotate around the axis of the transmission rod 352. Since the elastic deformation piece 355 is spirally wound outside the side wall of the transmission rod 352, and one end of the elastic deformation piece 355 is connected with the sliding piece 354, the elastic deformation piece 355 will not rotate with the transmission rod 352. Under the cooperation of the rotating limiting protruding column 353 and the spiral structure of the elastic deformation piece 355, the elastic deformation piece 355 moves longitudinally, and in turn drives the sliding piece 354 to move along the transmission rod 352.

[0043] In some embodiments, referring to Figure 3As shown, the output shaft of the clutch driving motor 356 is arranged in parallel with the transmission rod 352, and a first transmission gear set 357 is arranged between the clutch driving motor 356 and the transmission rod 352. The first transmission gear set 357 can adjust the rotating speed and torque, and change the power transmission direction. The overall layout of the clutch driving assembly 35 and the power assembly 33 is more compact.

[0044] Embodiment 2

[0045] The difference between this embodiment and embodiment 1 is that, referring to Figures 4 to 5 As shown, the frame 11 is provided with a limiting groove rail 4, and the movable door 12 is provided with a locking member 5 and a driving assembly 7 for driving the locking member 5 to extend into or out of the positioning groove 41. The driving assembly 7 includes a first elastic member 71 for driving the locking member 5 to move in the direction close to the positioning groove 41, a transmission member 72, and a control assembly 73 for driving the transmission member 72 to reciprocate in the horizontal direction. The locking member 5 is provided with a sliding groove, and the transmission member 72 is provided with a sliding block. The sliding groove has a V-shaped structure, which includes a transition section and first and second inclined sections arranged on the left and right sides of the transition section, respectively. In this embodiment, the first inclined section is on the left side, and the second inclined section is on the right side. In this embodiment, the sliding groove has a V-shaped structure with an opening facing the limiting groove rail 4.

[0046] For example, the limiting groove rail 4 can be arranged on the upper rail or the lower rail of the frame 11. Preferably, the limiting groove rail 4 is arranged on the upper rail to avoid affecting the user's access, and to avoid being contaminated, blocked, and affecting the normal use of the sliding door by dust, foreign matter, and the like.

[0047] Specifically, taking the opening of the door by moving the movable door 12 to the left and closing the door by moving it to the right as an example, the use principle of the sliding door of this embodiment is as follows:

[0048] In the normal state, the locking member 5 extends into the positioning groove 41 under the action of the driving assembly 7, and the movable door 12 and the frame 11 are locked with each other, and the movable door 12 is fixed at this position.

[0049] Referring to Figures 4 to 6 and Figure 8As shown, when it is needed to open the movable door 12 to the required position, the transmission member 72 is moved horizontally to the left by the control assembly 73, which drives the sliding block to move horizontally to the left, and the sliding block moves correspondingly to the left from the transition section in the sliding groove until the sliding block moves to the end of the first inclined section away from the transition section. In this process, the locking member 5 moves downward under the joint action of the sliding block and the sliding groove, so that the end of the locking member 5 extends out of the positioning groove 41, and the locking of the movable door 12 is released. After the movable door 12 moves to the required position, the locking member 5 moves upward under the action of the driving assembly 7, and the sliding block moves correspondingly to the right from the end of the first inclined section away from the transition section to the transition section in the sliding groove. The end of the locking member 5 extends into the positioning groove 41, and the movable door 12 is locked and fixed at this position.

[0050] As shown in FIG. 1, Figures 4 to 5 and Figure 7 As shown, when it is needed to open the movable door 12 to the required position, the transmission member 72 is moved horizontally to the left by the control assembly 73, which drives the sliding block to move horizontally to the left, and the sliding block moves correspondingly to the left from the transition section in the sliding groove until the sliding block moves to the end of the first inclined section away from the transition section. In this process, the locking member 5 moves downward under the joint action of the sliding block and the sliding groove, so that the end of the locking member 5 extends out of the positioning groove 41, and the locking of the movable door 12 is released. After the movable door 12 moves to the required position, the locking member 5 moves upward under the action of the driving assembly 7, and the sliding block moves correspondingly to the right from the end of the first inclined section away from the transition section to the transition section in the sliding groove. The end of the locking member 5 extends into the positioning groove 41, and the movable door 12 is locked and fixed at this position.

[0051] The movable door 12 of the sliding door can be fixed at any position, which meets the requirement of free control of the opening degree of the user and provides better use experience. Meanwhile, the driving assembly 7 converts the up-down telescopic movement of the locking member 5 into the horizontal reciprocating movement of the transmission member 72, so that when the control assembly 73 is manually operated, the force direction of the user when pushing and pulling left and right to open and close the movable door 12 can be more adapted, and the unlocking and locking operations of the movable door 12 are more convenient.

[0052] Compared with the closed loop sliding groove, the sliding groove 61 adopts a V-shaped structure. When the movable door 12 is stationary, the locking member 5 can extend into the positioning groove 41 to fix the movable door 12 at this position and freely control the opening degree of the sliding door. When it is needed to move the movable door 12 left and right, the locking member 5 can correspondingly extend out of the positioning groove 41 to enable the movable door 12 to move freely. The groove structure of the sliding groove 61 is simple and has low precision requirement, which is easier to manufacture.

[0053] In some embodiments, as shown in FIG. 1, Figures 4 to 8As shown, the driving assembly 7 comprises a base 74, the base 74 is provided with a horizontal bar 741 extending in horizontal direction, the transmission member 72 is slidingly arranged on the horizontal bar 741, the transmission member 72 is provided with an inner cavity, the inner cavity is provided with a deformable helical elastic member 721, the helical elastic member 721 is helically arranged outside the side wall of the horizontal bar 741, and the side wall of the horizontal bar 741 is provided with a limiting protrusion 742;

[0054] The control assembly 73 comprises a manual control assembly 73A and an electric control assembly 73B, the electric control assembly 73B comprises a rotating driving motor 732 for driving the horizontal bar 741 to rotate, at least one end of the helical elastic member 721 is connected with the transmission member 72, and the helical elastic member 721 is arranged in opposite rotation with the horizontal bar 741.

[0055] As shown in Figure 4 , Figure 5 and Figure 8 When it is needed to open or close the movable door 12 to a required position by using the manual control assembly 73A, the user manually drives the transmission member 72 to move along the corresponding direction of opening or closing of the movable door 12 by the manual control assembly 73A, so that the end of the locking member 5 extends out of the positioning groove 41 from the positioning groove 41, and the locking of the movable door 12 is released, at the same time, the transmission member 72 moves relative to the limiting protrusion 742 on the horizontal bar 741, and the helical elastic member 721 is compressed by the limiting protrusion 742. Then, the operating handle 731 is continuously pulled, the movable door 12 is moved in horizontal direction, until the movable door 12 is moved to the required position, the compressed helical elastic member 721 provides a restoring force to reset the transmission member 72, and the locking member 5 is automatically locked when the movable door 12 is positioned, so that the user does not need to specially operate, the use is more convenient, and the use experience is better.

[0056] As shown in Figures 5 to 7As shown, when it is required to open or close the movable door 12 to a desired position by using the electric control assembly 73B, the rotary drive motor 732 is started to drive the horizontal rod 741 to rotate forward or reverse, and the limiting block 742 is driven to rotate around the axis of the horizontal rod 741. Since the helical elastic member 721 is arranged outside the horizontal rod 741 and one end of the helical elastic member 721 is connected with the transmission member 72, the helical elastic member 721 will not rotate with the horizontal rod 741. Under the cooperation of the rotating limiting block 742 and the helical structure of the helical elastic member 721, the helical elastic member 721 moves horizontally, thereby driving the transmission member 72 to move, and driving the end of the locking member 5 to extend out of the positioning groove 41, thereby releasing the locking of the movable door 12, and the movable door 12 can move freely. After the movable door 12 is moved to the desired position, the rotary drive motor 732 is started again to reset the transmission member 72, thereby driving the end of the locking member 5 to extend into the positioning groove 41 from outside the positioning groove 41, and locking and fixing the movable door 12 at the position.

[0057] The limiting block 742 and the helical elastic member 721 have multiple functions. On the one hand, the limiting block 742 can limit the movement stroke of the helical elastic member 721 and the transmission member 72 on the horizontal rod 741, and the helical elastic member 721 can reset the transmission member 72. It can be understood that when the manual control assembly 73A is used to rotate the transmission member 72, the helical elastic member 721 has the function of the elastic reset member. On the other hand, when the control assembly 73 has both the manual control assembly 73A and the electric control assembly 73B, the limiting block 742 and the helical elastic member 721 can cooperate with the horizontal rod 741 and the rotary drive motor 732 to realize the automatic horizontal movement of the transmission member 72. If a conventional screw sliding block transmission mode is used, there will be a self-locking problem, which will interfere with the normal use of the driving mode of the manual control assembly 73A to move the transmission member 72. However, in the embodiment, the limiting block 742 and the helical elastic member 721 are used, so that the manual control assembly 73A and the electric control assembly 73B can be normally used, and the user can independently select whether to use a manual mode or an electric mode to move the transmission member 72 based on needs, so that the sliding door has higher flexibility and better use experience. At the same time, the manual control assembly 73A and the electric control assembly 73B can be fully integrated, and the overall structure is more compact.

[0058] In some embodiments, referring to Figures 5 to 7 As shown, the output shaft of the rotary drive motor 732 is arranged in the parallel direction of the horizontal rod 741, and a second transmission gear set 733 is arranged between the rotary drive motor 732 and the horizontal rod 741. The second transmission gear set 733 is arranged on one side of the base 74, and the manual control assembly 73A and the electric control assembly 73B have a more compact overall structure.

[0059] In some embodiments, referring to Figure 4 andFigure 8 As shown, the manual control assembly 73A includes an operation handle 731 movably arranged on the movable door 12 in a horizontal direction, and the operation handle 731 is movably connected with the transmission member 72.

[0060] Specifically, taking the movable door 12 moving to the left as opening the door and moving to the right as closing the door as an example, the use principle of the manual mode of opening / closing the movable door 12 in the embodiment is as follows:

[0061] When it is needed to open the movable door 12 to a required position, the user pulls the operation handle 731 to the left, driving the transmission member 72 to move to the left in a horizontal direction, and the locking member 5 moves downward under the joint action of the sliding block and the sliding groove, so that the end of the locking member 5 extends out of the positioning groove 41, and the locking of the movable door 12 is released. The operation handle 731 is continuously pulled to the left, the movable door 12 moves to the left under force, until the movable door 12 moves to the required position, and the external force is removed. The elastic recovery force of the compressed spiral elastic member 721 makes the transmission member 72 reset, and the end of the locking member 5 is driven to extend into the positioning groove 41 from outside the positioning groove 41, so as to lock and fix the movable door 12 at the position.

[0062] When it is needed to close the movable door 12 to a required position, the user pulls the operation handle 731 to the right, driving the transmission member 72 to move to the right in a horizontal direction, and the locking member 5 moves downward under the joint action of the sliding block and the sliding groove, so that the end of the locking member 5 extends out of the positioning groove 41, and the locking of the movable door 12 is released. The operation handle 731 is continuously pulled to the right, the movable door 12 moves to the right under force, until the movable door 12 moves to the required position, and the external force is removed. The elastic recovery force of the compressed spiral elastic member 721 makes the transmission member 72 reset, and the end of the locking member 5 is driven to extend into the positioning groove 41 from outside the positioning groove 41, so as to lock and fix the movable door 12 at the position.

[0063] Therefore, the locking member 5 can be automatically locked when the movable door 12 is positioned, without the user needing to perform special operation. Meanwhile, the opening / closing operation of the movable door 12 and the operation of unlocking / locking can be realized by pulling the operation handle 731 in the corresponding direction of opening or closing the movable door 12, so that the use is more convenient, and the use experience is better.

[0064] In some embodiments, the second elastic member is symmetrically arranged on both sides of the operation handle 731, so that the operation handle 731 can be automatically reset after the hand is released.
