[0052] The exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not intended to exhaust all possible methods of the present application, nor to limit the scope of the present application.

[0053] The embodiment of the present application provides a belt connecting device, which can be used to connect the door leaf of an automatic sliding door to a belt, such as Figure 1 , Figure 2 and Figure 3As shown, the belt connecting device may include a belt clip bracket 10, a belt clip 20, and a door leaf hanger 30. The belt clip 20 and the door leaf hanger 30 may be connected to the belt clip bracket 10, respectively.

[0054] In the automatic sliding door structure, the belt 40 (including the synchronous belt) can move around the pulleys on the left and right sides (that is, it is a ring belt). The belt 40 can change the movement direction by the pulleys to form an upper belt and a lower belt, and the movement directions of the upper belt and the lower belt are opposite (the upper belt and the lower belt are distinguished by the relative height of the two belt sections).

[0055] The belt connecting device provided in the present application may include at least two installation structures, which are respectively suitable for connecting the upper belt and the lower belt with the door leaf. Figure 2 The first mounting structure of the belt connecting device is shown, which can be suitable for connecting the upper belt. In the first mounting structure, the length direction of the belt clip bracket 10 can be perpendicular to the horizontal direction (ie, the extension direction of the belt). Figure 3 The second mounting structure of the belt connecting device is shown, which can be suitable for the connection of the lower belt. In the second mounting structure, the length direction of the belt clip bracket 10 can be parallel to the horizontal direction (i.e. the extension direction of the belt).

[0056] Specifically, Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the belt clip bracket 10 may include a belt clip connecting portion 11 and a hanger connecting portion 12 , the belt clip connecting portion 11 may be connected to the belt clip 20 , and the hanger connecting portion 12 may be connected to the door leaf hanger 30 .

[0057] Furthermore, the belt clip bracket 10 can be connected to the belt clip 20 and the door leaf hanger 30 respectively by bolts. Figure 7 and Figure 8 As shown, the bracket connecting portion 11 may be formed with a first hole group 111 and a second hole group 112. Figure 6 As shown, the belt clip 20 may be formed with tooth grooves 21 and bracket connecting holes 22. The first hole group 111 and the second hole group 112 may be connected to the bracket connecting holes 22 by bolts, thereby connecting the belt clip bracket 10 and the belt clip 20.

[0058] The first hole group 111 , the second hole group 112 , and the bracket connection hole 22 may each include one or more bolt holes, and the number of bolt holes included in the first hole group 111 , the second hole group 112 , and the bracket connection hole 22 may be the same and corresponding.

[0059] Preferably, Figure 7 and Figure 8As shown, the first hole group 111, the second hole group 112 and the bracket connecting hole 22 are all two holes. The setting direction of the first hole group 111 can be perpendicular to the setting direction of the second hole group 112, that is, the straight line passing through the center of the two holes in the first hole group 111 and the straight line passing through the center of the two holes in the second hole group 112 can be perpendicular. The setting directions of the first hole group 111 and the second hole group 112 can form an angle of 90 degrees relative to each other, so that the first hole group 111 and the second hole group 112 are respectively suitable for connecting the belt clip bracket 10 and the belt clip 20 under the first mounting structure and the second mounting structure.

[0060] Optionally, the number of bolt holes in the first hole group 111, the second hole group 112 and the bracket connecting hole 22 can also be three or more, and the setting directions of the first hole group 111 and the second hole group 112 can form a 90-degree angle relative to each other, that is, the figure formed by connecting the bolt holes in the first hole group 111 can form a 90-degree rotation angle relative to the figure formed by connecting the bolt holes in the second hole group 112.

[0061] like Figure 1 As shown, the belt 40 may be a synchronous toothed belt, that is, the inner side of the belt 40 of the automatic sliding door (the opposite side of the upper belt and the lower belt) may have belt teeth. Figure 6 As shown, the tooth grooves 21 formed on the belt clip 20 can mesh with the belt teeth of the belt 40, so that the belt clip 20 can be tightly connected to the belt 40. Preferably, the tooth grooves 21 of the belt clip 20 can be double-sided tooth grooves 21 (i.e., the tooth grooves 21 are distributed on the upper and lower surfaces of the contact portion between the belt clip and the belt), so that it can be tightly connected to the belt 40 in both the first installation structure and the second installation structure. The belt clip 20 can be connected to the bracket connection portion 11 of the belt clip bracket 10 after clamping the belt 40.

[0062] like Figure 2 , Figure 3 and Figure 7 As shown, the door leaf hanger 30 may include a first bracket connection portion 31 and a second bracket connection portion 32, and the hanger connection portion 12 of the belt clip bracket 10 may be formed with a third hole group 121. The first bracket connection portion 31 and the second bracket connection portion 32 may be connected to the third hole group 121 of the hanger connection portion 12 when the belt connection device is in the first installation structure and the second installation structure, respectively. That is, the belt clip bracket 10 may be connected to the first bracket connection portion 31 in a length direction perpendicular to the horizontal direction, and the belt clip bracket 10 may be connected to the second bracket connection portion 32 in a length direction parallel to the horizontal direction.

[0063] Preferably, the first bracket connection part 31 and the second bracket connection part 32 can be connected to the hanger connection part 12 by bolts. The first bracket connection part 31, the second bracket connection part 32 and the third hole group 121 can respectively include one or more bolt holes. The number of bolt holes respectively included in the first bracket connection part 31, the second bracket connection part 32 and the third hole group 121 can be the same and corresponding.

[0064] Preferably, the first bracket connection part 31, the second bracket connection part 32 and the third hole group 121 may include three bolt holes respectively, and the three bolt holes may be arranged in a triangle. The figure formed by sequentially connecting the bolt holes of the first bracket connection part 31 may form a 90-degree rotation angle relative to the figure formed by sequentially connecting the bolt holes in the second bracket connection part 32. Here, the first bracket connection part 31, the second bracket connection part 32 and the third hole group 121 may include four bolt holes respectively, and the four bolt holes may be arranged in a square.

[0065] Here, the first vertical distance ( Figure 2 , Figure 7 The second vertical distance (the distance in the vertical direction along the middle) between the line connecting the second hole group 112 and the center of the third hole group 121 Figure 3 The distance in the up-down direction, along Figure 7 The difference between the second vertical distance and the first vertical distance is the same as the height difference between the upper belt portion and the lower belt portion.

[0066] The first bracket connection portion 31 and the second bracket connection portion 32 may have the same height.

[0067] Optional, such as Figure 2 and Figure 3 As shown, the belt clip connection portion 11 of the belt clip bracket 10 may also be formed with one or more stopper holes 113. The stopper holes 113 may be oblong holes, which may be used to cooperate with the opening and closing door stopper of the automatic sliding door to limit the horizontal movement of the door leaf.

[0068] Preferably, Figure 5 and Figure 8 As shown, the plane of the belt clip connection part 11 and the plane of the hanger connection part 12 of the belt clip bracket 10 can be staggered by a certain distance in the plate thickness direction of the belt clip bracket 10 to adapt to the specific structure of the automatic sliding door. It can be understood that the belt clip connection part 11 and the hanger connection part 12 can also be located on the same plane, that is, the belt clip bracket 10 can be a flat sheet metal part.

[0069] It can be understood that the belt connecting device provided in this embodiment is particularly suitable for automatic sliding doors including at least two door leaves with opposite movement directions. However, it is not excluded that the belt connecting device can also be used for automatic sliding doors with a single door leaf or multiple door leaves with the same movement direction. Using the same belt connecting device in a variety of automatic sliding doors still has the advantages of saving mold costs and reducing parts costs.

[0070] The embodiment of the present application also provides an automatic sliding door, which may include the aforementioned belt connection device, as well as a belt 40 and a door leaf. The aforementioned belt connection device may connect the belt 40 and the door leaf respectively, that is, the belt clamp 20 may connect the belt, and the door leaf hanger 30 may connect the door leaf (for example, the door leaf may be connected to the bottom of the door leaf hanger), so that the door leaf may move with the belt. The belt 40 may be an endless belt.

[0071] Preferably, the automatic sliding door may include at least two belt connection devices and at least two door leaves with opposite movement directions. One door leaf may be connected to one or more belt connection devices. In particular, the belt 40 may be an endless belt and include an upper belt portion and a lower belt portion with opposite movement directions, at least one door leaf is connected to the upper belt portion via at least one belt connection device, and at least another door leaf is connected to the lower belt portion via at least one belt connection device. The length direction of the belt clip bracket 10 connected to the upper belt portion is perpendicular to the horizontal direction; the length direction of the belt clip bracket 10 connected to the lower belt portion is parallel to the horizontal direction.

[0072] The following briefly describes some of the beneficial effects of the above-mentioned embodiments of the present application.

[0073] The embodiments of the present application provide a belt connection device and an automatic sliding door, wherein the belt connection device can have at least two installation structures by changing the installation direction of the belt clip bracket, and the two installation structures can respectively connect the upper belt and the lower belt of the automatic sliding door. Compared with separately manufacturing two belt connection devices of different shapes, the technical solution of the present application can save mold costs and can also correspondingly reduce the parts costs of the belt connection device, especially the belt clip bracket and the door leaf hanger (it can be understood that using more common parts in industrial production and increasing the production quantity of a single part can reduce the corresponding parts production costs).

[0074] It is understood that in the present application, when the number of parts or components is not particularly limited, the number may be one or more, and the multiple here means two or more. For the case where the number of parts or components shown in the drawings and / or described in the specification is a specific number such as two, three, four, etc., the specific number is usually exemplary and not restrictive, and it can be understood as multiple, that is, two or more, but this does not mean that the present application excludes the case of one.

[0075] It should be understood that the above embodiments are merely exemplary and are not intended to limit the present application. Those skilled in the art may make various modifications and changes to the above embodiments under the guidance of the present application without departing from the scope of the present application.
