In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] This embodiment provides a sliding door, which can be installed at the entrance and exit of the periphery of enterprises, factories, communities, etc. As Figures 1 to 3 shown, the sliding door includes a door row 10 and a driving assembly 20. A lower beam 11 is provided at the bottom of the door row 10, and an installation groove 111 with an opening facing downwards is provided at the bottom of the lower beam 11. The driving assembly 20 is arranged at the bottom of the lower beam 11 and fixed on the ground. The orthographic projection of the driving assembly 20 on the horizontal plane is located within the orthographic projection of the lower beam 11 on the horizontal plane. At least part of the driving assembly 20 is located in the installation groove 111 and connected to the door row 10. The driving assembly 20 is configured to drive the door row 10 to move back and forth along a preset direction.

[0041] With the above settings, the driving component 20 is hiddenly arranged in the installation groove 111. By setting the orthographic projection of the driving component 20 on the horizontal plane within the orthographic projection of the lower beam 11 on the horizontal plane, the lower beam 11 can shield and cover the driving component 20, achieving waterproof, dustproof and stain-proof effects, avoiding rust and corrosion of the driving component 20, extending the service life of the driving component 20, ensuring the safety of the equipment and personnel, reducing potential safety hazards, and making the driving component 20 basically invisible from the outside, thus achieving an aesthetic appearance.

[0042] As Figure 1 shown, a plurality of support casters 80 are arranged at the bottom of the lower beam 11 along a preset direction. The plurality of support casters 80 are used to support the door row 10, so that the door row 10 can be stably supported on the ground and move along the ground.

[0043] In an optional embodiment, as Figure 3 and Figure 4 shown, the driving component 20 includes a driving motor 21, a speed reducer 22, a driving gear 23 and a rack 24. The speed reducer 22 is connected to the output end of the driving motor 21, the driving gear 23 is connected to the output shaft of the speed reducer 22, the rack 24 is fixed on the groove wall of the installation groove 111 and extends along a preset direction, and the driving gear 23 meshes with the rack 24. The driving motor 21 drives the output shaft of the speed reducer 22 to rotate, thereby driving the driving gear 23 to rotate. When the driving gear 23 rotates, it will drive the rack 24 engaged therewith to move along a preset direction, so that the door row 10 can translate linearly. By adopting the driving mode of the above driving motor 21, speed reducer 22 and gear rack 24, the transmission is more accurate and the transmission efficiency is higher, thereby improving the accuracy of opening and closing the door.

[0044] In an optional embodiment, the driving motor 21 is a DC24V motor. In the prior art, the driving motor 21 is usually powered by a 220V AC power supply, which has great potential safety hazards. Therefore, by changing the driving motor 21 from a 220V AC power supply motor to a DC24V DC motor and using a safe voltage for driving, it is not easy to cause electric shock accidents, eliminating the voltage safety hazards and ensuring the safety during use.

[0045] In an optional embodiment, in combination with Figure 3 and Figure 4 , the rack 24 is fixed on one of the two opposite side walls of the installation groove 111. Specifically, in this embodiment, as can be seen from Figure 3 , the rack 24 is fixed on the left side wall of the installation groove 111, the output shaft of the speed reducer 22 is arranged upward, and the driving gear 23 is arranged horizontally in the installation groove 111. With such a setting, the speed reducer 22 and the driving gear 23 can be arranged in the vertical direction, with a compact structure and being more easily shielded and covered by the lower beam 11.

[0046] Specifically, in this embodiment, as Figure 1 shown, due to the existence of the supporting casters 80, there is a certain distance between the lower beam 11 and the ground. As Figure 3 shown, the driving gear 23 is completely located within the installation groove 111, achieving waterproof, dustproof, and stain-proof functions, avoiding rust and corrosion of the driving gear 23. A part of the driving motor 21 and the speed reducer 22 is located within the installation groove 111, and the other part is located outside the installation groove 111 but can also be covered by the lower beam 11. Moreover, the driving motor 21 and the speed reducer 22 themselves also have a housing to achieve the effect of waterproof, dustproof, and stain-proof.

[0047] In an alternative embodiment, the axial width of the driving gear 23 is greater than the width of the rack 24. When the ground is uneven, it will cause the upper and lower movement of the door row 10, and the rack 24 will also move up and down accordingly. At this time, the rack 24 will engage with the upper or lower part of the driving gear 23. By setting the axial width of the driving gear 23 to be greater than the width of the rack 24, even if the door row 10 moves up and down, the rack 24 can always mesh and drive with the driving gear 23.

[0048] In an alternative embodiment, as Figure 3 and Figure 4 shown, the sliding door further includes a lower limit component 30. The lower limit component 30 includes a wheel shaft 31 and a lower limit wheel 32. The wheel shaft 31 is vertically arranged, and the lower limit wheel 32 is rotatably arranged on the wheel shaft 31. The rack 24 is fixed to one of the two opposite side walls of the installation groove 111, and the circumferential surface of the lower limit wheel 32 abuts against the other of the two opposite side walls of the installation groove 111. In this embodiment, the rack 24 is fixed to the left side wall of the installation groove 111, the driving gear 23 meshes with the rack 24 on the left side, and the circumferential surface of the lower limit wheel 32 abuts against the right side wall of the installation groove 111. Through the combined action of the driving gear 23 and the lower limit wheel 32, the moving direction of the door row 10 can be restricted, preventing the door row 10 from shifting during movement, resulting in misalignment between the driving gear 23 and the rack 24 and causing movement jamming.

[0049] As Figure 4 shown, a set of lower limit components 30 are respectively arranged on both sides of the driving component 20 along the length direction of the door row 10. In this way, through the combined cooperation of the driving gear 23 and the two lower limit wheels 32, the moving direction of the door row 10 is further restricted, preventing the door row 10 from shifting during movement, resulting in misalignment between the driving gear 23 and the rack 24 and causing movement jamming.

[0050] In an alternative embodiment, as Figure 4As shown, the sliding door further includes a support assembly 40. The support assembly 40 includes a bracket 41 and a support wheel 42 rotatably provided on the bracket 41. The support wheel 42 is horizontally arranged and its axis is perpendicular to the preset direction. The top of the support wheel 42 is higher than the driving gear 23. When the door panel 10 encounters a relatively deep pit during movement, the door panel 10 moves downward and abuts against the support wheel 42. That is to say, when the door panel 10 moves downward to the limit position, the support wheel 42 will abut against the bottom of the installation groove 111, playing a role in supporting the lower beam 11 and preventing the lower beam 11 from contacting and rubbing against the driving gear 23, resulting in abnormal noise or jamming.

[0051] In an alternative embodiment, as Figure 4 shown, the sliding door further includes a fixing plate 50. The speed reducer 22, the wheel shaft 31, and the bracket 41 are all fixed on the fixing plate 50. By providing the fixing plate 50, the driving assembly 20, the lower limit assembly 30, and the support assembly 40 can all be integrated on the fixing plate 50, with a high degree of integration, reasonable layout, delicate and compact structure, and saving space occupancy.

[0052] In an alternative embodiment, as Figure 1 shown, the sliding door further includes a driven assembly 70. The driven assembly 70 is arranged at an interval from the driving assembly 20 along the preset direction, and the driven assembly 70 is also hiddenly arranged directly below the lower beam 11. Specifically, as Figure 5 shown, the driven assembly 70 includes a driven gear 71 and a support seat 72. The driven gear 71 is rotatably provided on the support seat 72. The driven gear 71 is the same as the driving gear 23, and is also horizontally arranged and meshes with the rack 24 for transmission, so as to ensure the stable operation of the door panel 10.

[0053] In an alternative embodiment, as Figure 5 shown, the above-mentioned lower limit assembly 30 and support assembly 40 are also arranged beside the driven assembly 70. The bottom of the support seat 72 is also provided with a fixing plate 50, and the lower limit assembly 30 and support assembly 40 beside the driven assembly 70 are also integrally integrated on the fixing plate 50 to form an integrated structure. Through the common cooperation of the driven gear 71 and the two lower limit wheels 32 beside it, the moving direction of the door panel 10 is further restricted, preventing the door panel 10 from shifting during movement, resulting in misalignment between the driving gear 23 and the rack 24 and causing movement jamming. By providing a support wheel 42 beside the driven gear 71, it can play a role in supporting the lower beam 11 and preventing the lower beam 11 from contacting and rubbing against the driven gear 71, resulting in abnormal noise or jamming.

[0054] As Figure 1 and Figure 2As shown in the figure, the sliding door further includes a main box body 60. The main box body 60 is arranged beside the driving assembly 20. The inside of the main box body 60 is used to accommodate electrical components such as a controller and wiring harness that are electrically connected to the driving assembly 20. The main box body 60 is set in a gantry structure. The door row 10 passes through between the main box bodies 60. Two opposite upper limit wheels 63 are rotatably arranged at the top inside the main box body 60. The two upper limit wheels 63 are respectively in rolling cooperation with the two sides of the top of the door row 10. Through the cooperation of the two upper limit wheels 63 and the upper end of the door row 10, it is prevented that the upper end of the door row 10 is skewed during the movement. Under the combined action of the upper limit wheels 63, the gears and the lower limit wheels 32, the door row 10 can be kept walking in a straight line stably.

[0055] As Figure 2 shown, the main box body 60 includes two columns 61 and a cross beam 62 connected between the tops of the two columns 61. The door row 10 is located between the two columns 61. When the door row 10 encounters a relatively high raised mound during the movement, the door row 10 may move up to the limit position. At this time, the upper part of the door row 10 will abut against the lower surface of the cross beam 62, preventing the door row 10 from moving up too high and causing the gear to disengage from the rack 24.

[0056] As Figure 2 shown, a switch limit inductor 64 is arranged at the bottom of the column 61. Magnets that are inductively matched with the switch limit inductor 64 are respectively arranged at two different positions of the door row 10 in a preset direction. The switch limit inductor 64 reaches the two limit positions of the opening and closing of the door row 10 by sensing the magnets at two different positions.

[0057] As Figure 1 shown, the sliding door further includes a gantry 90. When the door row 10 is completely closed, in the closed state as Figure 1 shown, the door row 10 passes through the gantry 90. The gantry 90 can provide lateral support for the door row 10 to keep the door row 10 stable when it is closed.

[0058] Further, as Figure 6 shown, limit members 91 are respectively arranged on both sides inside the gantry 90. An opening area is jointly defined between the two limit members 91. When the door row 10 is closed, the door row 10 enters the opening area, and the limit members 91 on both sides can provide lateral support for the door row 10 to keep the door row 10 stable when it is closed.

[0059] Further, as Figure 6 and Figure 7As shown, a guiding inclined surface 911 is provided on one side of the limiting member 91 close to the door row 10, and two deviation rectifying wheels 12 are provided at the end of the door row 10. When the door row 10 is closed, if the door row 10 is slightly deviated, through the cooperation of the deviation rectifying wheels 12 and the guiding inclined surface 911, the deviation of the door row 10 can be rectified, so that the door row 10 accurately enters the opening area between the two limiting members 91 to realize the closing of the door row 10.

[0060] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
