[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings.

[0027] Reference Figures 1 to 10 A sliding door with a hidden guide rail comprises a door body 1, a guide rail 2 arranged at the bottom of the door body 1, and a driving mechanism 3 arranged at the top of the door body 1 and driving the door body 1 to move along the guide rail 2, the guide rail 2 is provided with a slide groove 21, the bottom end of the door body 1 is provided with a moving part 11 that can slide in the slide groove 21, the left and right sides of the slide groove 21 are provided with grooves 22, the groove 22 is provided with a plurality of baffles 4 that can move in the left and right directions and can extend out of the groove 22, and the matching baffles 4 on the left and right sides are engaged with each other to cover and block the slide groove 21, the groove 22 is provided with a reset mechanism 5 that can drive the baffle 4 to move toward the outside of the groove 22, the moving part 11 includes a push plate 111 arranged at the baffle 4, and a push plate mechanism 6 that can make the baffles 4 on both sides move toward the inside of the groove 22 is provided between the baffle 4 and the push plate 111. In this way, the baffles 4 on the left and right sides will be closed to cover and block the slide groove 21 on the track at ordinary times, so as to hide the guide rail 2 and prevent it from being exposed to the outside, thereby preventing dust and debris from entering the slide groove 21, facilitating the sliding of the caster in the slide groove 21, and improving its service life. At the same time, it can also reduce the trouble of cleaning the slide groove 21. When the moving part 11 slides along the slide groove 21, the push plate 111 thereon moves the baffles 4 on both sides toward the inside of the groove 22 through the push plate mechanism 6, so that the moving part 11 can move forward and backward along the slide groove 21, and after the moving part 11 passes, the baffles 4 on the left and right sides are moved toward the outside of the groove 22 through the reset mechanism 5, so that the baffles 4 on the left and right sides are re-engaged with each other to cover and block the slide groove 21. In addition, the opening and closing of the door body 1 is controlled by the driving mechanism 3, so that it is easy to operate.

[0028] In this solution, the driving mechanism 3 includes a driving block 31 disposed on the top of the door body 1 and capable of driving the door body 1 to move along the slide groove 21, and a linear module 32 disposed on the top of the door body 1 and driving the driving block 31 to move, wherein the linear module 32 is fixed on the wall, and includes a slide rail 321 disposed above the door body 1, and a plurality of rollers 322 are rotatably disposed on the slide rail 321, and the driving block 31 is disposed on the slide rail 321 and slidably cooperates with the rollers 322, so as to facilitate the linear module 32 to drive the driving block 31 to move, thereby driving the door body 1 to move. There is also an induction switch 7 disposed on the door body 1 and connected to the linear module 32 for communication, so as to control the operation of the linear module 32, thereby controlling the opening and closing of the door body 1.

[0029] In this solution, the slide grooves 21 are two and are respectively arranged on the left and right sides of the guide rail 2. The door body 1 has two leaves and corresponds to the slide grooves 21 one by one. The moving part 11 includes a plurality of casters 112 arranged on the door body 1.

[0030] In the present embodiment, the reset mechanism 5 includes a reset spring 51 which is arranged in the groove 22 and abuts against the inner side of the baffle 4. Specifically, a docking joint for assembling the reset spring 51 is provided on the inner side of each baffle 4 and the inner wall of the groove 22, so that the baffle 4 is pushed to move toward the outside of the groove 22 by the reset spring 51, so that the baffles 4 on both sides are engaged with each other to cover and block the slide groove 21.

[0031] In this solution, a first strip plate 23 is provided on both sides of the left and right sides of the slide groove 21, and a second strip plate 24 is provided below the first strip plate 23. The height of the upper surface of the first strip plate 23 is the same as the height of the upper surface of the track. The first strip plate 23 and the second strip plate 24 are combined to form the groove 22. In this way, the slide groove 21 is covered and shielded by the cooperation of the first strip plate 23 and the baffle 4 in the groove 22.

[0032] In the present embodiment, a guide pair 41 is provided between the two adjacent front and rear baffles 4 for guiding the baffle 4 to move in the left and right directions. The guide pair 41 includes a guide groove 411 provided on one side of the front end or rear end of the baffle 4, and a guide rail 412 provided on the adjacent baffle 4 and cooperating with the guide groove 411, so that the baffle 4 can move in the left and right directions in the groove 22 without deviation through the guide pair 41.

[0033] In this embodiment, the baffle plate 4 includes a first baffle plate 43 located on the left side of the groove 22, and a second baffle plate 44 located on the right side of the groove 22. A V-shaped groove 431 is provided on the outer side of the first baffle plate 43, and a plug 441 matching the V-shaped groove 431 is provided on the outer side of the second baffle plate 44. The V-shaped groove 431 and the plug 441 are connected to each other, which facilitates the connection between the first baffle plate 43 and the second baffle plate 44 on the left and right sides.

[0034] In the present embodiment, the push plate mechanism 6 includes a push-up structure 61 arranged between the push plate 111 and the baffle plate 4, and the push-up structure 61 includes a first push-up slope 611 arranged on the rear side of the bottom of the baffle plate 4, and a second push-up slope 612 arranged at the front end of the push plate 111 and matched with the first push-up slope 611 on the left and right sides. Specifically, the first push-up slopes 611 on the baffle plates 4 on the left and right sides cooperate to form a V-shaped push-up surface, and the shape of the second push-up slope 612 is also V-shaped, so that when the push plate 111 passes by, the first push-up slope 611 is pushed by the second push-up slope 612, so that the baffle plates 4 on both sides move into the groove 22 to avoid blocking the caster from moving in the slide groove 21. Furthermore, a third pushing inclined surface 613 is provided on the front bottom side of the baffle 4, and a fourth pushing inclined surface 614 is provided at the rear end of the push plate 111 and cooperates with the third pushing inclined surfaces 613 on the left and right sides. Specifically, the third pushing inclined surfaces 613 on the baffles 4 on the left and right sides cooperate to form a V-shaped pushing inclined surface, and the shape of the fourth pushing inclined surface 614 is also V-shaped, so that after the casters slide over, the baffles 4 on both sides will not close quickly under the action of the reset mechanism 5, but have a certain buffer, thereby reducing noise and preventing the baffles 4 on the left and right sides from being damaged by a large impact.

[0035] In this embodiment, a roller 615 is provided at the bottom of the baffle 4 and between the first push-up slope 611 and the third push-up slope 613. Specifically, the first push-up slope 611 cooperates with the third push-up slope to form a V-shaped surface at the bottom of the baffle 4, and the roller 615 is arranged at the apex of the V-shaped surface, so that the push plate 111 can be used to push open the baffles 4 on the left and right sides.

[0036] In the present embodiment, the push plate mechanism 6 includes a magnetic push structure 62 arranged between the push plate 111 and the baffle 4, and the magnetic push structure 62 includes a first magnet 621 arranged at the bottom of the first baffle 43, a second magnet 622 arranged at the bottom of the second baffle 44 and magnetically attracted to the first magnet 621, a third magnet 623 arranged at the left side of the front end of the push plate 111 and magnetically repelled by the first magnet 621, and a fourth magnet 624 arranged at the right side of the front end of the push plate 111 and magnetically repelled by the second magnet 622. In this way, when the push plate 111 passes by, the first magnet 621 repels the third magnet 623, and the second magnet 622 repels the fourth magnet 624, thereby causing the baffles 4 on both sides to move into the groove 22. Furthermore, a fifth magnet 625 that magnetically repels the third magnet 623 is provided on the left side of the rear end of the push plate 111, and a sixth magnet 626 that magnetically repels the fourth magnet 624 is provided on the right side of the rear end of the push plate 111. In this way, after the caster slides over, the baffles 4 on both sides will not close quickly under the action of the reset mechanism 5, but will have a certain buffer, thereby reducing noise and preventing the baffles 4 on the left and right sides from being damaged by a large impact.

[0037] The working process of the sliding door is as follows: when the door body 1 needs to be opened, the user triggers the induction switch 7, the induction switch 7 sends a signal to the linear module 32, the linear module 32 drives the driving block 31 to move, and drives the door body 1 to move along the slide groove 21 of the guide rail 2. The push plate 111 on the moving part 11 moves with the door body 1, and when the push plate 111 approaches the baffle 4, the push plate mechanism 6 starts to work. If the push-up structure 61 is adopted, the second push-up inclined surface 612 at the front end of the push plate 111 contacts the first push-up inclined surface 611 at the rear side of the bottom of the baffle 4. As the push plate 111 continues to move, the second push-up inclined surface 612 pushes the first push-up inclined surface 611, so that the baffles 4 on both sides overcome the elastic force of the reset spring 51 and move to the inside of the groove 22, and the caster 112 can move back and forth smoothly in the slide groove 21. After the caster 112 slides over, the third push-up inclined surface 613 at the front side of the bottom of the baffle 4 contacts the fourth push-up inclined surface 614 at the rear end of the push plate 111. Due to the V-shaped structure of the two, the baffle 4 will not close quickly under the action of the reset spring 51, but will slowly reset, playing a buffering role. If the magnetic push structure 62 is adopted, the third magnet 623 and the fourth magnet 624 at the front end of the push plate 111 will repel each other with the first magnet 621 at the bottom of the first baffle 42 and the second magnet 622 at the bottom of the second baffle 43, respectively, so that the baffles 4 on both sides move toward the inside of the groove 22; the fifth magnet 625 and the sixth magnet 626 at the rear end of the push plate 111 will repel each other with the third magnet 623 and the fourth magnet 624, respectively, so that the baffle 4 will slowly reset after the caster 112 slides over. When the door body 1 is closed, the induction switch 7 controls the linear module 32 again to make the door body 1 move in the opposite direction, and the process is similar to that when the door is opened.

[0038] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description.
