[0005] The fixing structure can ensure the position accuracy of the positioning assembly on the fixing guide rail, and thus the position accuracy of other components is determined. Since the pulley assembly is arranged on the positioning assembly, the movement of the pulley assembly is within a predetermined range. Meanwhile, the fixing effect of the clamping assembly can enhance the stability of the entire fixing structure, and force transmission and balance can be effectively achieved. During the operation of the equipment, various external forces such as vibration and impact may be encountered. If the positioning assembly is not clamped firmly on the fixing guide rail, it may be displaced or shaken. However, the positioning assembly can be effectively fixed by the clamping assembly, which can effectively resist these external forces and keep the positioning assembly stable. Since the opening is arranged on the fixing guide rail, a convenient operation channel is provided for the user, so that the clamping assembly can be easily tightened to fix the positioning assembly at the bottom of the fixing guide rail by using a locking screwdriver, without the need to disassemble the entire fixing structure. The installation speed is significantly accelerated. The carbon brush support assembly is arranged on the pulley assembly, and the roller assembly is arranged on the carbon brush support assembly. Finally, the transmission assembly is arranged on the roller assembly. This layer-by-layer arrangement forms a coherent power transmission system. When power is transmitted to the pulley assembly, the carbon brush support assembly can be driven to move cooperatively with the pulley assembly by connecting the carbon brush support assembly to the pulley assembly. Meanwhile, the roller assembly is arranged on the carbon brush support assembly, so that the roller assembly can be driven by the movement of the carbon brush support assembly. Finally, after the transmission assembly is arranged on the roller assembly, the movement state of the roller assembly can be transmitted to the door body, so that the door body can move stably on the fixing guide rail.

[0006] In one of the embodiments, the positioning assembly comprises a first positioning plate, a second positioning plate, a third positioning plate and a fourth positioning plate, the first positioning plate is provided with a first bolt hole, the third positioning plate is provided with a second bolt hole, the clamping assembly is arranged on the first positioning plate and located at the first bolt hole, the second positioning plate is arranged on the first positioning plate, the third positioning plate is arranged on the second positioning plate, the clamping assembly is arranged on the third positioning plate and located at the second bolt hole, and the fourth positioning plate is arranged on the third positioning plate and fixed on the fixed guide rail through a fixing bolt.

Secondly, the layer-by-layer arrangement from the first positioning plate to the fourth positioning plate forms a multi-stage positioning system, and each layer of the positioning plate further refines and accurately positions on the basis of the previous layer. The first positioning plate lays a foundation for the entire positioning assembly and provides a relatively accurate initial position reference. The second positioning plate arranged on the first positioning plate can supplement and fine-tune the positioning of the first positioning plate. Since the third positioning plate is connected with the second positioning plate and the clamping assembly at the same time, the stress can be evenly distributed on multiple support points, and the pressure borne by each support point will be reduced, so that a larger total load can be borne, the fixing strength of the clamping assembly on the positioning assembly is further increased, the displacement of the positioning assembly due to external force is effectively avoided, and the stability of the entire fixing structure is enhanced.

The first clamping assembly and the second clamping assembly pass through different bolt holes respectively, so that the clamping force generated during the clamping process can be more evenly distributed on the positioning assembly, avoiding the case of single-point concentrated force when the fixed structure is running or subjected to external impact, better balancing external forces, preventing the positioning assembly from tilting or shifting, and prolonging its service life.

[0008] In one of the embodiments, the first clamping assembly includes a first clamping seat, a first connecting block, and a first locking bolt, the first clamping seat abuts against the positioning assembly, the first connecting block is arranged on the first clamping seat, and the first locking bolt is located at the first bolt hole and connects the first connecting block and the positioning assembly. By arranging the first connecting block on the first clamping seat and then connecting the first connecting block and the positioning assembly through the first bolt hole by using the first locking bolt, the user can use a screwdriver or other tools to extrude the first clamping seat, so that the first clamping seat can stably clamp the positioning assembly on the fixed guide rail, ensuring the predetermined position of the positioning assembly on the fixed guide rail. At the same time, the first clamping seat will generate a clamping force during the clamping process, which is evenly distributed on the contact surface between the positioning assembly and the fixed guide rail.

At the same time, the second clamping seat will generate a clamping force during the clamping process, which is evenly distributed on the contact surface between the positioning assembly and the fixed guide rail. This uniform pressure distribution can prevent the positioning assembly and the fixed guide rail from deforming or wearing in the local area due to excessive pressure. At the same time, the second clamping seat and the first clamping seat jointly constitute a multi-point fixing mode, which greatly enhances the stability of the positioning assembly on the fixed guide rail, makes it better resist external forces from all directions, prolongs the service life of the positioning assembly, and also makes the stress of the entire sliding door device more reasonable and safe.

Since the buckle moves with the rotation of the belt pulley assembly, the carbon brush support can maintain the certainty of its relative position during the operation of the equipment by means of the stable movement track of the buckle, and can move along the designed path, avoiding the influence of unstable position on the function. At the same time, this arrangement can effectively utilize the space around the buckle to arrange the carbon brush support, and through reasonable layout, the components of the equipment can be arranged more compactly, reducing the overall space occupied by the equipment.

Meanwhile, the fixing effect of the clamping assembly 3 can enhance the stability of the whole fixing structure, and the force transmission and balance can be effectively realized.

Secondly, the layer-by-layer arrangement from the first positioning plate 21 to the fourth positioning plate 24 forms a multi-stage positioning system, and each layer of positioning plate further refines and accurately positions on the basis of the previous layer, and the first positioning plate 21 lays a foundation for the entire positioning assembly 2 and provides a relatively accurate initial position reference, and the second positioning plate 22 arranged on the first positioning plate 21 can supplement and fine-tune the positioning of the first positioning plate 11. Since the third positioning plate 23 is connected with the second positioning plate 22 and the clamping assembly 3 at the same time, the stress can be evenly distributed on multiple support points, and the pressure borne by each support point will be reduced, so that a greater total load can be borne, the fixing strength of the clamping assembly 3 to the positioning assembly 2 is further increased, the displacement of the positioning assembly 2 due to external force is effectively avoided, and the stability of the entire fixing structure is enhanced.

This symmetrical structure can achieve force balance during the operation of the door, improve the load-bearing capacity and movement stability of the roller assembly 5, and also improve its movement flexibility and diversity.

[0047] like Figure 2 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the transmission assembly 6 includes a transmission shaft 61 and a transmission block 62. The transmission shaft 61 is disposed on the roller assembly 5, and the transmission block 62 is disposed on the transmission shaft 61. By disposing of the transmission shaft 61 on the roller assembly 5, a motion transmission channel is established between the roller assembly 5 and other components. The transmission shaft 61, as an intermediate medium, can effectively transmit the motion characteristics of the roller assembly 5, enabling different parts of the entire mechanical system to be interconnected and achieve coordinated motion. Disposing of the transmission block 62 on the transmission shaft 61 further expands the motion conversion function. When the transmission shaft 61 receives the motion of the roller assembly 5, the motion mode of the pulley assembly 1 can be transmitted to the door body through the transmission block 62, allowing the door body to move smoothly on the fixed track.
