DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0029] It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once an item is defined in one drawing, it need not be further defined and explained in subsequent drawings.

[0030] At present, for door and window manufacturers, the structure of the manual sliding door that has been put on the market is not suitable for the built-in motor electric sliding door scheme. If a built-in motor electric sliding door is redeveloped, it is difficult for some door and window manufacturers to bear the cost of time and money. In order to solve this problem, the present application provides a sliding door with an external motor.

[0031] Please refer to Figures 1 to 5 A sliding door with an external motor, at least comprising a door frame 2 fixed on a wall, an upper track 21 fixed in the door frame 2, and a door leaf 3 arranged in the door frame 2 and sliding along the upper track 21, further comprising an external motor structure 22 installed on the side of the upper track 21, comprising a horizontally arranged driving motor 43, a transmission assembly, and a door leaf hanging piece 45;

[0032] The driving motor 43 is connected with the transmission assembly, and drives the transmission assembly to run in the horizontal direction;

[0033] The door leaf hanging piece 45 is fixed on the transmission assembly and runs in the horizontal direction with the transmission assembly;

[0034] The door leaf 3 is fixedly connected with the door leaf hanging piece 45 and runs in the horizontal direction with the door leaf hanging piece 45.

[0035] Among them, the external motor structure 22 can be directly installed on the existing upper track 21, without the need for large-scale modification of the door body, greatly reducing the modification cost and difficulty. Placing the external motor structure on the side of the upper track 21 not only protects the motor from the external environment, but also facilitates daily maintenance and repair.

[0036] The transmission assembly uses rollers and a conveyor belt 46 to form the transmission assembly. At least two rollers (including a driving roller 44 connected to the driving motor 43 and a driven roller 47) are fixedly installed on the upper track 21, and then the conveyor belt 46 is wound around the rollers. When the driving motor 43 rotates, the driving roller 44 drives the conveyor belt 46 to run, thereby achieving transmission.

[0037] The door leaf hanger 45 includes at least two main parts: a first connecting part 451 fixedly connected to the conveyor belt 46, and a second connecting part 452 fixedly connected to the door leaf 3. The first connecting part 451 can be designed in a sleeve shape with a fixed through hole for the conveyor belt 46 to pass through, so as to firmly fix the door leaf hanger 45 on the conveyor belt 46. The second connecting part 452 is designed with a connecting surface 453 that is attached to the door leaf 3, and is connected to the door leaf 3 by bolts or other fasteners, ensuring that the door leaf 3 can run smoothly with the door leaf hanger 45.

[0038] In order to further improve the reliability and convenience of the system, the external motor structure 22 is provided with a power supply 41 and a control circuit 42. The power supply 41 provides power for the driving motor 43, and the control circuit 42 adjusts the rotation direction of the motor, thereby controlling the opening and closing of the door leaf 3. Through power driving, users can easily operate the large sliding door 1.

[0039] In actual application, in order to protect the external motor structure 22 and improve the overall aesthetics, a fixed frame 23 and a maintenance cover plate 4 are designed. The fixed frame 23 is installed on the indoor side of the upper track 21 and is used to fix the external motor structure 22. The maintenance cover plate 4 is connected to the fixed frame 23 by a hinged way and can be opened for maintenance, and is closed to protect the internal structure at ordinary times. Through this design, the problem of difficult operation of the large sliding door 1 is successfully solved, and large-scale modification of the existing door body is avoided, reducing the time and cost. This not only improves the user experience and reduces the safety risk, but also prolongs the service life of the door system and reduces the long-term maintenance cost. This solution makes the application of the large sliding door 1 more flexible, which helps to improve the overall aesthetics and functionality of the building.

[0040] Compared with the prior art of modifying the door body into an electric door, the present application directly applies the external motor structure 22 to the existing manual sliding door without the need for large-scale modification of the door body structure, greatly reducing the modification cost and difficulty, making the electric upgrade simple and feasible. The external motor structure is installed on the indoor side of the upper track, which not only protects the motor from external environment and prolongs the service life, but also facilitates daily maintenance and repair. Through the carefully designed transmission assembly and door leaf hanger 45, the present application realizes the smooth electric operation of the large sliding door 1, greatly improving the user experience.

[0041] Further, the transmission assembly comprises a fixed roller fixed on the upper rail 21, and a conveying belt 46 wound on the fixed roller and running; the driving motor 43 is connected with the fixed roller, so as to drive the conveying belt 46 to run around the fixed roller.

[0042] Wherein, the transmission assembly composed of the fixed roller and the conveying belt 46 arranged on the upper rail 21 realizes the power transmission from the driving motor 43 to the door leaf 3. The fixed roller is fixed on the upper rail 21, and provides support and guidance for the conveying belt 46. The conveying belt 46 is wound on the fixed roller and can run under the driving of the fixed roller. The driving motor 43 is connected with the fixed roller, and drives the conveying belt 46 to run by controlling the rotation of the fixed roller. In some specific embodiments, the fixed roller can include a driving roller 44 and a driven roller 47. The driving roller 44 is directly connected with the driving motor 43 and is driven to rotate by the driving motor 43; the driven roller 47 is used for tensioning the conveying belt 46 and providing a guiding function. The axes of the driving roller 44 and the driven roller 47 are arranged in parallel, so as to ensure the smooth running of the conveying belt 46. The conveying belt 46 can be made of various materials, such as rubber, nylon or composite materials, so as to meet different load and use environment requirements. The width and thickness of the conveying belt 46 can be selected according to the weight and size of the door leaf 3.

[0043] Further, the door leaf hanger 45 is fixed on the conveying belt 46 and runs with the conveying belt 46.

[0044] Wherein, the door leaf hanger 45 is fixed on the conveying belt 46, so that the door leaf hanger 45 can run with the conveying belt 46. The door leaf hanger 45 serves as an intermediate connecting piece, which is fixedly connected with the conveying belt 46 on one hand, and is connected with the door leaf 3 on the other hand, so as to realize the power transmission. This design not only has a simple structure and is easy to implement, but also can ensure the stability and reliability of the movement of the door leaf 3. At the same time, since the door leaf hanger 45 is fixed on the conveying belt 46, this connection method is also convenient for maintenance and replacement. Through this design, the external motor structure 22 can effectively drive the door leaf 3 to translate along the upper rail 21, so as to realize the automatic opening and closing of the sliding door. Compared with the traditional door leaf 3 driving mode, this scheme has the advantages of simple structure, easy installation and simple maintenance, and improves the use convenience and reliability of the sliding door.

[0045] Further, the door leaf hanger 45 at least comprises a first connecting part 451 fixed with the conveying belt 46, and a second connecting part 452 fixed with the door leaf 3. The first connecting part 451 is sleeved on the conveying belt 46 and has a fixed through hole through which the conveying belt 46 passes. The second connecting part 452 has at least a connecting surface 453 abutting against the door leaf 3. A bolt passes through the connecting surface 453 and the door leaf 3 to fix the second connecting part 452 with the door leaf 3, so that the door leaf 3 can run along the horizontal direction with the door leaf hanger 45.

[0046] Wherein, please refer to Figure 5The first connecting part 451 achieves stable connection with the conveying belt 46 by being sleeved on the conveying belt 46 and provided with a fixed through hole. This design can ensure that the door leaf hanger 45 can run smoothly with the conveying belt 46 and will not be detached or shaken. The second connecting part 452 achieves reliable connection with the door leaf 3 by the connecting surface 453 adhering to the door leaf 3 and being fixed by bolts. This connection method not only ensures the firmness between the door leaf 3 and the door leaf hanger 45, but also facilitates installation and disassembly. Through this double connection design, the door leaf hanger 45 can accurately transmit the movement of the conveying belt 46 to the door leaf 3, so that the door leaf 3 can run smoothly along the horizontal direction with the door leaf hanger 45. This design not only improves the stability and reliability of the entire movable door structure, but also simplifies the installation and maintenance process.

[0047] The first connecting part 451 can have various implementation manners. For example, the fixed through hole can be designed as a circle, an ellipse or a rectangle to adapt to conveying belts 46 with different cross-sectional shapes. The inner wall of the through hole can be provided with anti-skid lines or rubber pads to increase the friction with the conveying belt 46 and further improve the stability of the connection. The first connecting part 451 can also be designed as an adjustable structure, for example, by adjusting the tightness of the connecting part through bolts to adapt to conveying belts 46 with different thicknesses.

[0048] The connection between the second connecting part 452 and the door leaf 3 can also have various implementation manners. In addition to using bolts for fixation, buckle type connection, welding or adhesive fixation can also be used. The connecting surface 453 can be designed as a plane, a curved surface or a shape with grooves to increase the contact area and adhesion with the door leaf 3. In order to improve the strength and stability of the connection, a plurality of bolt holes can be provided on the connecting surface 453 to adopt a multi-point fixation manner.

[0049] The material of the door leaf hanger 45 can use lightweight high-strength materials such as aluminum alloy or engineering plastic to reduce the overall weight while ensuring sufficient strength and durability.

[0050] Further, the roller at least includes a driving wheel 44 and a driven wheel 47, and the driving wheel 44 is connected with the driving motor 43 and rotates under the driving of the driving motor 43.

[0051] Among them, please refer to Figure 3 , Figure 4The active wheel 44 is directly connected with the driving motor 43, and the driving motor 43 drives the active wheel 44 to rotate, and then drives the conveying belt 46 to run. The driven wheel 47 plays a role in supporting and guiding the conveying belt 46, and ensures that the conveying belt 46 can stably run. Through the cooperation of the driving motor 43, the active wheel 44, the driven wheel 47 and the conveying belt 46, the stable movement of the door leaf 3 is realized. The driving motor 43 provides power, the active wheel 44 transmits power to the conveying belt 46, and the conveying belt 46 drives the door leaf hanger 45 to move, thereby realizing the horizontal movement of the door leaf 3. The setting of the driven wheel 47 ensures the running track of the conveying belt 46, and improves the stability and reliability of the system. This simple and efficient transmission mode not only can realize the stable movement of the door leaf 3, but also is convenient for maintenance and repair.

[0052] In some embodiments, the active wheel 44 can adopt the form of a gear or a pulley, and is engaged or frictionally driven with the conveying belt 46. The driven wheel 47 can be a smooth cylindrical wheel or a guide wheel with grooves. The number of active wheels 44 and driven wheels 47 can be adjusted according to actual needs, for example, two active wheels 44 and multiple driven wheels 47 can be provided to increase the tension and stability of the conveying belt 46.

[0053] Further, the conveying belt 46 is a belt that is wound on the active wheel 44 and the driven wheel 47 and runs in a loop.

[0054] The belt can form a closed-loop transmission system between the active wheel 44 and the driven wheel 47. The active wheel 44 is connected with the driving motor 43. When the driving motor 43 operates, the active wheel 44 drives the belt to run. The driven wheel 47 plays a role in guiding and supporting the belt, and ensures that the belt can run in a loop along the predetermined path. The door leaf hanger 45 is fixed on the belt and runs with the belt, thereby driving the door leaf 3 to translate in the horizontal direction. This transmission structure is simple and reliable. The belt has certain elasticity and flexibility, which can reduce noise and vibration during operation. At the same time, the belt transmission is convenient for maintenance and replacement. By adjusting the distance between the active wheel 44 and the driven wheel 47, the tightness of the belt can be easily adjusted to ensure the stability of the transmission. In addition, using the belt as the conveying belt 46 has the advantages of light weight and low cost, which is beneficial to reduce the weight and production cost of the entire door structure. Compared with the chain or gear transmission structure, the belt transmission structure can realize the stable, reliable and low-noise operation of the door leaf 3.

[0055] Further, the power supply 41 is connected with the driving motor 43 and supplies power for the operation of the driving motor 43.

[0056] Wherein, by connecting the power supply 41 with the driving motor 43, it can ensure that the driving motor 43 obtains a continuous and stable power supply, thereby guaranteeing the normal operation of the entire moving door structure. The introduction of the power supply 41 solves the problem of power source in the moving door structure. It provides the necessary power for the driving motor 43, so that the motor can continue to run, and then drive the transmission assembly and the door leaf hanging piece 45 to move. Through the connection of the power supply 41 and the driving motor 43, the entire moving door system forms a complete power transmission chain, the power supply 41 provides power, the driving motor 43 converts electrical energy into mechanical energy, the transmission assembly transmits mechanical energy to the door leaf hanging piece 45, and finally realizes the smooth movement of the door leaf 3. This design optimizes the energy transmission efficiency, reduces energy loss, and at the same time improves the response speed and control accuracy of the entire system.

[0057] Further, the external motor structure 22 further comprises a control circuit 42, the control circuit 42 is connected with the power supply 41 and the driving motor 43, and the power supply 41 supplies power for the operation of the control circuit 42; the control circuit 42 controls the rotation direction of the driving motor 43, thereby controlling the translation direction of the door leaf 3.

[0058] Wherein, by connecting the control circuit 42 with the power supply 41 and the driving motor 43, and obtaining the power required for operation through the power supply 41, and then controlling the rotation direction of the driving motor 43, the precise control of the translation direction of the door leaf 3 is realized. By changing the rotation direction of the driving motor 43, the opening and closing direction of the door leaf 3 can be flexibly controlled. This not only improves the operation convenience of the moving door, but also enhances the automation degree of the system. At the same time, this design also provides the possibility for realizing more complex door control functions (such as remote control, timing switch, etc.).

[0059] Further, it further comprises a fixed frame body 23 fixed to the indoor side of the upper rail 21, and the fixed frame body 23 comprises a first mounting area 231 for fixing the external motor structure 22.

[0060] The fixed frame body 23 is installed on the indoor side of the upper rail 21 and includes a first mounting area 231. The first mounting area 231 is specifically used to fix the external motor structure 22. By providing the fixed frame body 23 and the first mounting area 231, a stable and reliable mounting position is provided for the external motor structure 22. This design ensures that the mounting position of the external motor structure 22 is fixed and stable, avoiding the possibility of shaking or displacement of the motor during operation, thereby improving the operational stability and safety of the entire moving door system. Mounting the external motor structure 22 on the fixed frame body 23 makes the connection between the motor and the door leaf 3 more compact and coordinated, which is beneficial to improving the accuracy and smoothness of the translation of the door leaf 3. This design makes the installation and removal of the external motor structure 22 more convenient, facilitating later maintenance and repair work. Mounting the external motor structure 22 on the fixed frame body 23 towards the indoor side can effectively protect the motor from external environmental factors and prolong its service life.

[0061] In some specific embodiments, the fixed frame body 23 can be in the shape of an "L". The "L" shaped fixed frame body 23 has two mounting plates, one of which is fixed to the side of the upper rail 21 close to the indoor side and does not interfere with the door leaf 3 running in the upper rail 21. The external motor structure 22 is installed in the "L" shaped mounting area formed by the two mounting plates, and is fixed to the door leaf 3 through the door leaf hanging piece 45, so as to drive the translation of the door leaf 3 by electricity.

[0062] Further, a maintenance cover plate 4 is also included, which is hingedly connected to the fixed frame body 23 at one end and extends towards the outdoor direction at the other end, forming a cover structure that closes the first mounting area 231.

[0063] The maintenance cover plate 4 is hingedly connected to the fixed frame body 23 at one end, which can be easily opened and closed, allowing maintenance personnel to easily access the external motor structure 22 for repair and maintenance. The other end of the maintenance cover plate 4 extends towards the outdoor direction, forming a cover structure that closes the first mounting area 231. This design can effectively protect the external motor structure 22 from dust, moisture and other external environmental factors, prolonging the service life of the equipment. In addition, the maintenance cover plate 4 can shield the external motor structure 22, making the entire moving door structure look more neat and beautiful.

[0064] The above description is only an embodiment of the present application and is not intended to limit the protection scope of the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
