In existing door sliding mechanisms, the tracks are typically exposed to the external environment. This structure has several drawbacks: firstly, dust and debris can easily enter the tracks through openings above them, affecting not only the smoothness of the door's movement but also accelerating wear between the door's moving parts and the tracks, thus shortening the equipment's lifespan; secondly, exposed tracks are unsightly and increase the difficulty and frequency of daily cleaning, causing inconvenience to users. Utility Model Content
[0003] Therefore, the purpose of this utility model is to provide a concealed track that can hide the opening above the slide to prevent dust or debris from entering and is aesthetically pleasing.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows:
[0005] A concealed track for a sliding door includes a guide rail, a slide groove disposed on the guide rail, and a slide block disposed within the slide groove and slidable along the slide groove. The slide groove has unfoldable or retractable baffles on both its left and right sides. When unfolded, the baffles cover and block the opening above the slide groove. The slide groove also has storage slots on both its left and right sides for storing the retracted baffles. Each storage slot has a moving mechanism that can move left and right to drag the baffles to retract. A drive structure is provided between the moving mechanism and the slide block to drive the moving mechanism to move.
[0006] In a preferred embodiment of this utility model, the baffle is hinged to the upper end of the moving mechanism, and there is a gap between the moving mechanism and the upper side wall of the storage groove to form a storage area for storing the baffle when it is retracted.
[0007] In a preferred embodiment of this utility model, a first return spring is provided between the baffle and the moving mechanism to allow the baffle to unfold. The baffle is arc-shaped, and inclined guide surfaces that cooperate with the upper side of the baffle are provided on the left and right side walls of the opening above the slide groove.
[0008] In a preferred embodiment of this utility model, the upper side of the extended end of the baffle is a horizontal plane and is flush with the upper end surface of the guide rail.
[0009] In a preferred embodiment of the present invention, the moving mechanism includes a guide seat disposed in the storage slot, several moving blocks disposed on the guide seat and movable left and right, and a second return spring disposed between the storage slot and the moving blocks and capable of resetting the moving blocks. The upper end of the moving block is provided with a hinge joint, and the baffle is provided with a hinge part that can be hinged to the hinge joint.
[0010] In a preferred embodiment of this utility model, the guide seat is provided with a plurality of sliding grooves that slide with the moving block, and guide ribs are provided on the front and rear side walls of the sliding grooves. Guide grooves that cooperate with the guide ribs are provided on the front and rear sides of the moving block.
[0011] In a preferred embodiment of this utility model, the hinge joint is provided with a first hinge hole, the hinge part is provided with a second hinge hole communicating with the first hinge hole, a hinge shaft that can connect the two in series passes through the first hinge hole and the second hinge hole, a notch is provided in the middle of the hinge part, the first return spring is sleeved on the hinge shaft and disposed at the notch, one end of the first return spring abuts against the lower side of the baffle, and the other end abuts against the upper side of the moving block.
[0012] In a preferred embodiment of the present invention, a limiting plate is provided on the guide seat and on the side near the slide to prevent the moving block from disengaging from the slide groove.
[0013] In a preferred embodiment of this utility model, the bottom of the movable block is provided with a slot, and the driving structure includes a first magnetic block disposed in the slot and a second magnetic block disposed on the left and right sides of the slide and corresponding to the first magnetic block.
[0014] In a preferred embodiment of this utility model, the slide includes a lower seat body disposed below, an upper seat body disposed above, and a support plate disposed between the upper seat body and the lower seat body. The storage slots on both sides are spaced apart to form a channel through which the support plate can pass. There are at least two second magnetic blocks, which are paired up and disposed on the front and rear sides of the lower seat body respectively. The second magnetic block located at the frontmost side is disposed in front of the support plate, and the second magnetic block located at the rearmost side is disposed behind the support plate.
[0015] The beneficial effects of this utility model are as follows: The concealed track includes a slide block that slides within a guide rail groove. Inside the groove, on both its left and right sides, are unfoldable or retractable baffles. When unfolded, the baffles cover and block the opening above the groove. Inside the groove, on both its left and right sides, are storage slots for storing the retracted baffles. These storage slots contain a moving mechanism that can move left and right to drag the baffles to retract. A drive structure is provided between the moving mechanism and the slide block to drive the moving mechanism. In this way, when not in use, the baffles on both sides unfold and close together, covering and blocking the opening above the groove, thus concealing the groove and preventing it from being exposed to the outside. This prevents dust and debris from entering the groove, facilitates the movement of the slide block within the groove, reduces wear, increases service life, and reduces the hassle of cleaning the inside of the groove. When the slide block slides along the slide groove, the driving structure on it drives the moving mechanism to move, thereby moving the baffle towards the storage groove to retract it and store it in the storage groove, thus avoiding obstructing the passage of the slide block.

[0021] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.
[0022] Reference Figures 1 to 5A concealed track for a sliding door includes a guide rail 1, a slide groove 11 disposed on the guide rail 1, and a slide block 2 disposed in the slide groove 11 and slidable along the slide groove 11. The slide groove 11 is provided with unfoldable or retractable baffles 3 on its left and right sides. When the baffles 3 on both sides are unfolded, they can cover and block the opening above the slide groove 11. The slide groove 11 is provided with storage slots 12 on its left and right sides for storing the baffles 3 when retracted. The storage slots 12 are provided with a moving mechanism 4 that can move left and right to drag the baffles 3 to retract. A driving structure 5 is provided between the moving mechanism 4 and the slide block 2 to drive the moving mechanism 4 to move. Normally, the baffles 3 on both sides unfold and then close together to cover and conceal the opening above the slide 11, thus hiding the slide 11 and preventing it from being exposed to the outside. This prevents dust and debris from entering the slide 11, facilitates the movement of the slide 2 within the slide 11, reduces wear, extends its service life, and reduces the hassle of cleaning the inside of the slide 11. When the slide 2 slides along the slide 11, the driving structure 5 drives the moving mechanism 4 to move, which in turn moves the baffle 3 towards the storage slot 12 to retract it and store it inside the storage slot 12, thus avoiding obstructing the passage of the slide 2. After the slide 2 has passed, the moving mechanism 4 and the baffle 3 have reset components that allow the baffle 3 to return to its unfolded state, and then cover and conceal the opening above the slide 11 again.
[0023] In this solution, the baffle 3 is hinged to the upper end of the moving mechanism 4. There is a gap between the moving mechanism 4 and the upper side wall of the storage groove 12 to form a storage area 121 for storing the baffle 3 when it is retracted. In this way, the moving mechanism 4 will pull the baffle 3 down and move it into the storage groove 12, so that the baffle 3 can be stored in the storage area 121.
[0024] In this design, a first return spring 31 is provided between the baffle 3 and the moving mechanism 4 to allow the baffle 3 to be unfolded. The baffle 3 is arc-shaped. Inclined guide surfaces 13 that cooperate with the upper side of the baffle 3 are provided on the left and right side walls of the opening above the slide groove 11. Specifically, the inclined guide surface 13 is an arc surface. In this way, the baffle 3 can be smoothly retracted into the storage area 121 or unfolded from the storage area 121 by the inclined guide surface 13 abutting against the upper side of the baffle 3. At the same time, the first return spring 31 ensures that the baffle 3 can remain straight after unfolding, and then cooperate with the baffle 3 on the other side to cover and block the opening above the slide groove 11.
[0025] In this design, the upper side of the extended end of the baffle 3 is a horizontal plane and is flush with the upper surface of the guide rail 1. This way, when the baffle 3 is unfolded, it can be flush with the upper end of the guide rail 1, making it look neater and more aesthetically pleasing.
[0026] In this design, the moving mechanism 4 includes a guide seat 41 disposed within the storage slot 12, several moving blocks 42 disposed on the guide seat 41 and movable left and right, and a second return spring 43 disposed between the storage slot 12 and the moving blocks 42, which can reset the moving blocks 42. The upper end of each moving block 42 is provided with a hinge joint 421, and the baffle 3 is provided with a hinge portion 32 that can be hinged to the hinge joint 421. Because the baffle 3 is hinged to the moving blocks 42, when the driving structure 5 drives the moving blocks 42 to move into the storage slot 12, the moving blocks 42 can drive the baffle 3 to move into the storage slot 12, causing it to retract into the storage area 121. Then, after the slide 2 passes, the second return spring 43 causes the moving blocks 42 to reset, thereby allowing the baffle 3 to unfold within the storage area 121.
[0027] In this solution, the guide seat 41 is provided with a plurality of moving grooves 411 that slide with the moving block 42. The front and rear side walls of the moving grooves 411 are provided with guide ribs 412. The front and rear sides of the moving block 42 are provided with guide grooves 425 that cooperate with the guide ribs 412. This ensures that the moving block 42 will not deviate when moving in the left and right directions within the moving grooves 411.
[0028] In this design, the hinge joint 421 is provided with a first hinge hole 422, and the hinge part 32 is provided with a second hinge hole 321 that communicates with the first hinge hole 422. A hinge shaft 33 that can connect the two in series passes through the first hinge hole 422 and the second hinge hole 321. A notch 322 is provided in the middle of the hinge part 32. The first return spring 31 is sleeved on the hinge shaft 33 and is located at the notch 322. One end of the first return spring 31 abuts against the lower side of the baffle 3, and the other end abuts against the upper side of the moving block 42.
[0029] In this solution, a limiting plate 413 is provided on the guide seat 41 and on the side near the slide 2 to restrict the moving block 42 from disengaging from the slide groove 11. In this way, when the moving block 42 is reset, its position is restricted by the limiting plate 413. When the limiting plate 413 abuts against the moving block 42, the baffle 3 is in the unfolded state, and the baffles 3 on both sides will move closer to each other and join together.
[0030] In this design, the bottom of the movable block 42, above the limiting plate 413, is provided with a slot 423. The driving structure 5 includes a first magnetic block 51 disposed in the slot 423 and second magnetic blocks 52 disposed on the left and right sides of the slide block 2 and corresponding to the first magnetic block 51. Further, the slide block 2 includes a lower seat body 21 disposed below and slidable within the slide groove 11, an upper seat body 22 disposed above for supporting the door body, and a support plate 23 disposed between the upper seat body 22 and the lower seat body 21. The storage slots 12 on both sides are spaced apart to form a channel through which the support plate 23 can pass. Specifically, the slide groove 11 is I-shaped, with the upper seat body 22 located below the slide groove 11 and the lower seat body 21 located below the opening of the slide groove 11. The lower seat 21 has several mounting slots 211 on both the left and right sides for assembling the second magnetic blocks 52. There are at least two second magnetic blocks 52, which are paired up and respectively located on the front and rear sides of the lower seat 21. The second magnetic block 52 located at the front is located in front of the support plate 23, and the second magnetic block 52 located at the rear is located behind the support plate 23. This ensures that when the slide 2 moves back and forth, the baffle 3 is already retracted into the storage area 121 when the support plate 23 passes through the corresponding baffle 3, so as not to obstruct its passage.
[0031] In this design, a stop block 424 is provided on the upper end of the movable block 42 and on the side near the slide 2. The stop blocks 424 on both sides of the movable block 42 can be inserted into each other to support the movable block 42 and make it more stable under force. When the baffle 3 is retracted in the storage area 121, the stop block 424 can abut against the left or right side of the support plate 23 to restrict the movable block 42 from resetting and thus prevent the support plate 23 from passing through.
[0032] In this scheme, the driving structure 5 can be used not only in the non-contact way of repulsion between the magnetic blocks, but also in the way of direct contact. For example, a push block is provided on the side of the moving block 42 near the slide 2, and a push plate is provided on the lower body 21 that can abut against the push block. The push block and the push plate have abutting slopes on their front and rear sides. In this way, the push plate pushes the push block to move into the storage groove 12, thereby pushing the moving block to move and retract the baffle 3 into the storage area 121.
[0033] In summary, the working principle of this track is as follows:
[0034] Normal state: The left and right side baffles 3 unfold and join together to cover and block the opening above the slide groove 11, hide the slide groove 11, prevent dust and debris from entering, reduce wear on the slide seat 2, improve service life, and reduce cleaning trouble.
[0035] When the slide 2 slides: the slide 2 moves, and the driving structure 5 on it (such as the magnetic force of the first magnetic block 51 and the second magnetic block 52 or the push plate and the push block push against each other) drives the moving mechanism 4 to move, which drives the baffle 3 to move towards the storage groove 12 and puts it into the storage groove 12 to avoid obstructing the slide 2 from passing through.
[0036] After the slide block 2 passes: due to the action of the moving mechanism 4 and the reset components on the baffle 3 (such as the first reset spring 31 and the second reset spring 43), the baffle 3 resets and unfolds, covering the opening above the slide groove 11 again and hiding it.
[0037] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
