[0002] In the prior art, automatic doors are widely used in the fields of machinery and equipment, construction, etc., and the effect of automatic opening and closing of doors can be achieved through sensing devices.

[0003] For example, the Chinese patent document with publication number CN214091496U discloses a belt-driven automatic door device, including a door beam, a door panel and a belt drive assembly; the door panel is slidably mounted on the door beam along the front-to-back direction, the belt drive assembly is provided with a driving wheel, a driven wheel and a driving belt, the driving wheel and the driven wheel are arranged one after the other, the axial directions of the driving wheel and the driven wheel are parallel to each other and perpendicular to the front-to-back direction, the driving wheel and the driven wheel are both mounted on the door beam, the driving belt is wound around the driving wheel and the driven wheel, the driving wheel and the driving belt are synchronously driven, the driving belt is an open belt, and both ends of the driving belt are fixedly connected to the door panel. The door panel is driven to slide forward and backward through the opening.

[0004] In the technical solution of the above patent document, the driven wheel and the driving wheel are both fixed structures. During long-term operation, the rollers, guide rails, etc. of the mobile door will have certain deformation. The rollers, driving wheels, and driven wheels on the mobile door will have certain displacement. Therefore, the belt connecting the driving wheel, the driven wheel, and the mobile door will have the problem of tilting, which will cause the belt to rub against the side walls of the driving wheel and the driven wheel to generate noise, and also cause the belt to wear. Utility Model Content

[0005] The utility model aims to provide a driven pulley floating connection structure and an electric sliding door, so as to solve the problem that after long-term use of the existing automatic door, the belt will rub against the side walls of the driving wheel and the driven wheel.

[0006] To achieve the above-mentioned purpose, an embodiment of the utility model provides a driven pulley floating connection structure for connecting the transmission belt of an electric sliding door, comprising a mounting seat, a self-balancing connecting seat and a driven wheel; the mounting seat is arranged in the installation box of the electric sliding door, the mounting seat is provided with a connecting part, one end of the self-balancing connecting seat is provided with a conversion part, a connecting shaft connects the connecting part and the conversion part, so that the self-balancing connecting seat is rotatably connected to the connecting part; the other end of the self-balancing connecting seat is provided with a mounting position, the driven wheel is rotatably connected to the mounting position, and the rotation axis of the driven wheel is perpendicular to the axis of the connecting shaft; the transmission belt is wound around the driven wheel.

[0007] Furthermore, the connecting portion is a rib plate extending upward, and the connecting axis passes through the thickness direction of the rib plate.

[0008] Furthermore, a bottom plate is provided on the mounting seat, and the bottom plate is punched and bent upward to form the rib plate.

[0009] Furthermore, the mounting seat is formed by stamping and bending a sheet metal part.

[0012] The above one or more technical solutions in the driven pulley floating connection structure provided by the embodiment of the utility model have at least the following technical effects:

[0013] Because the other end of the self-balancing connector is connected to the driven wheel, the transmission belt is wound around the driven wheel, and the rotation axis of the driven wheel is perpendicular to the axis of the connecting shaft. When the driven wheel deflects due to excessive load on the transmission belt, the self-balancing connector also deflects. The connecting shaft connects the connecting part of the mounting seat and the adapter of the self-balancing connector, so that the self-balancing connector is rotatably connected to the connecting part. Therefore, the self-balancing connector can be automatically straightened by the tension of the transmission belt, ensuring that the driven wheel automatically adjusts in the direction of the tension of the transmission belt, thereby avoiding the friction between the transmission belt and the side wall of the driven wheel caused by the tilt and misalignment of the transmission belt and the driven wheel, avoiding noise when opening and closing the door, and also playing a good protective role for the transmission belt.

[0015] The above one or more technical solutions in the electric sliding door provided by the embodiment of the utility model have at least the following technical effects:

[0016] Under the action of the floating connection structure of the driven pulley, the electric sliding door ensures that the driven pulley automatically adjusts to the pulling direction of the transmission belt, thereby avoiding the friction between the transmission belt and the side wall of the driven wheel caused by the tilt and misalignment of the transmission belt and the driven pulley, avoiding noise when opening and closing the door, and also playing a good protective role for the transmission belt.

[0029] In one embodiment of the electric sliding door of the utility model, please refer to Figure 1 to Figure 5 The electric sliding door 200 can automatically correct the driving belt of the sliding door 140 to avoid the problem of noise caused by the friction of the driving belt 230. Specifically, the electric sliding door 200 includes a driven pulley floating connection structure 100, a mounting box 210, a main driving mechanism 220, a driving belt 230 and two sliding doors 240. The driven pulley floating connection structure 100 and the main driving mechanism 220 are arranged at both ends of the mounting box 210. Specifically:

[0030] The driven pulley floating connection structure 100 comprises a mounting seat 110, a self-balancing connecting seat 120 and a driven wheel 130. The mounting seat 110 is arranged in the mounting box 210 of the electric sliding door 200, and the mounting seat 110 is provided with a connecting portion 111, one end of the self-balancing connecting seat 120 is provided with a transfer portion 121, and a connecting shaft 140 connects the connecting portion 111 and the transfer portion 121, so that the self-balancing connecting seat 120 is rotatably connected to the connecting portion 111. The other end of the self-balancing connecting seat 120 is provided with a mounting position 123, and the driven wheel 130 is rotatably connected to the mounting position 123, and the rotation axis of the driven wheel 130 and the axis of the connecting shaft 140 are perpendicular to each other.

The installation box 210 is also provided with a track 250, and two sliding doors 240 are suspended on the track 250. The upper and lower sides of the driving belt 230 are respectively connected to a sliding door 240.

[0032] The electric sliding door of the above embodiment ensures that the driven wheel 130 automatically adjusts to the pulling direction of the transmission belt 230 under the action of the driven pulley floating connection structure, thereby avoiding the phenomenon that the transmission belt 230 and the driven wheel 130 are tilted and misaligned, causing the transmission belt 230 to rub against the side wall of the driven wheel 130, avoiding noise when opening and closing the door, and also playing a good protective role for the transmission belt 230. Specifically, the connecting shaft 140 connects the connecting portion 111 of the mounting seat and the adapter portion 121 of the self-balancing connecting seat, so that the self-balancing connecting seat 120 is rotatably connected to the connecting portion 111. Therefore, the self-balancing connecting seat 120 can automatically adjust to the pulling direction of the transmission belt 230 by the pulling force of the transmission belt 230, ensuring that the driven wheel 130 automatically adjusts to the pulling direction of the transmission belt 230, thereby avoiding the phenomenon that the transmission belt 230 and the driven wheel 130 are tilted and misaligned, causing the transmission belt 230 to rub against the side wall of the driven wheel 130, avoiding noise when opening and closing the door, and also playing a good protective role for the transmission belt 230.

[0033] For further information, please refer to Figure 5 The connecting portion 111 is a rib plate extending upward, and the connecting shaft 140 passes through the thickness direction of the rib plate. Specifically, the rib plate and the connecting shaft 140 are connected, which has a simple structure, is easy to process and form, and has low cost. In addition, the connecting shaft 140 passes through the thickness direction of the rib plate, which not only enables the rib plate to withstand a large force, but also effectively prevents deformation.

[0034] For further information, please refer to Figure 3 and Figure 5 The mounting seat 110 is provided with a bottom plate 112, and the bottom plate 112 is punched and bent upward to form a rib plate. Specifically, the punching and bending process is simple to operate, reduces the processing difficulty, and improves the processing efficiency.

[0035] Furthermore, the mounting seat 110 is formed by stamping and bending a sheet metal part, which saves materials and reduces the difficulty of processing.

[0036] For further information, please refer to Figure 3 The adapter 121 is provided with a mounting groove 122, and the mounting groove 122 forms two upper and lower connecting pieces of the adapter 121, and the mounting groove 122 is clamped on the rib plate. Specifically, the mounting groove 122 is clamped on the rib plate, and the connecting shaft 121 connects the connecting piece and the rib plate clamped on the mounting groove 122, thereby enhancing the stability of the self-balancing connecting seat 120, reducing the possibility of deflection of the driven wheel 130, and improving the self-correction effect of the connecting shaft 140.

[0037] For further information, please refer to Figure 3 The other end of the self-balancing connecting seat 120 is extended with two side plates 124, and a mounting position 123 is formed between the two side plates 124, and the driven wheel 130 is arranged in the mounting position 123. Specifically, the mounting position 123 formed by the two side plates 124 enhances the rotation stability of the driven wheel 130.
