Description
Technical Field
[0001] This utility model relates to the field of sliding door technology, specifically to an electric drive structure for a sliding door. Background Technology
[0002] A sliding door is a type of door that can be both pushed and pulled. When closing, it is pushed into the doorway from inside or outside the vehicle to close and seal it. When opening, it slides along the inside or outside of the vehicle after being moved a certain distance away from the doorway. Due to its excellent sealing performance and aesthetic appeal, sliding doors are widely used in rail transit vehicles such as high-speed trains and subways.
[0003] Currently, the use of electric drive structures lacks a manual drive structure. Traditional electric drive structures for sliding doors typically employ ball screw drives, relying on a motor for power and a control system to automatically open and close the door. However, in actual use, when power outages or control system malfunctions, the door will fail to open and close properly, causing significant inconvenience to passengers and staff, and potentially endangering safety. Therefore, this paper proposes an electric drive structure for sliding doors that incorporates a manual drive structure. By utilizing both electric and manual drive methods, the flexibility and safety of sliding doors can be improved, adapting to different usage scenarios and enhancing overall performance.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0017] To facilitate the use of both electric and manual drive methods, improve the flexibility and safety of sliding doors, and thus enhance their performance, such as... Figure 1-5 As shown, the electric drive structure for a sliding door of this utility model includes a right side plate 1, an active component 4, and a transition component 5. A left side plate 2 is provided on one side of the right side plate 1. A mounting bracket 3 is bolted between the right side plate 1 and the left side plate 2. The active component 4 is rotatably connected to the bottom of the mounting bracket 3 on one side of the right side plate 1. The transition component 5 is rotatably connected to the top of the active component 4 on one side of the right side plate 1. A manual control component 6 is provided on the other side of the right side plate 1. An electric drive component 8 is provided on the top of the manual control component 6 on the other side of the right side plate 1. The active component 4 includes an active gear 401, and a guide rod 402 is bolted to one side of the active gear 401. The transition component 5 includes a rotating frame 501. The surface of the rotating frame 501 is provided with active toothed teeth 502 and driven toothed teeth 503, and the active gear 401 is connected to the active toothed teeth 502 through meshing. The outer surface of the rotating frame 501 is provided with a limiting groove 504 corresponding to the active gear 401.
[0018] In use, a manual drive mechanism is added through the drive gear 401, guide rod 402, rotating frame 501, drive tooth 502, driven tooth 503 and limit groove 504. By using toothed transmission, the flexibility and safety of the sliding door in different working environments are improved.
[0019] To improve the ease of driver conversion, for example, such as Figure 2 , Figure 3 As shown, this utility model also includes an installation plate 101 on one side of the right side plate 1. A guide sleeve 102 is bolted to one side of the installation plate 101, and the guide sleeve 102 is sleeved and connected to the guide rod 402. A guide post 103 is bolted to the other side of the installation plate 101, and the guide post 103 passes through the right side plate 1 through a reserved hole. A conversion screw 104 is threaded to the other side of the right side plate 1 through a reserved threaded hole, and one end of the conversion screw 104 is rotatably connected to the installation plate 101 through a rotating shaft.
[0020] In use, a quick conversion mechanism is added through the mounting plate 101, guide sleeve 102, guide post 103 and conversion screw 104, and the conversion operation between electric drive and manual drive structure is completed by using threaded connection and sliding displacement.
[0021] For example, such as Figure 4 , 5 As shown, the present invention also includes a guide rod 402 with one end connected to an insert block 403 by bolts, and a protrusion 404 welded to the outer surface of the insert block 403; The outer surface of the rotating frame 501 is provided with a movable groove 505 on one side of the limiting groove 504. A sleeve rod 506 is installed on one side of the rotating frame 501 through a bearing, and the sleeve rod 506 passes through the mounting plate 101 through a reserved opening. The right side plate 1 is connected to the sleeve rod 506 through the reserved groove. One end of the sleeve rod 506 is connected to the limiting seat 507 by bolts. The right side plate 1 includes a protective cover 9.
[0022] During use, the movable groove 505 facilitates the improvement of the stability of the meshing connection with the driven gear 7, and the sleeve rod 506 and the limit seat 507 facilitate the connection of the mounting plate 101 to provide auxiliary guidance and support for the rotating frame 501.
[0023] For example, such as Figure 6As shown, the present invention also includes a hand control component 6 comprising a rocker arm 601, and the rocker arm 601 is mounted on the right side plate 1 via a bearing. One end of the rocker arm 601 is connected by a bolt to a sleeve 602 corresponding to the insert block 403. A limiting piece 603 corresponding to the protrusion 404 is provided inside the sleeve 602.
[0024] In use, the rocker arm 601, the sleeve 602, and the limiting piece 603 facilitate the insertion and transmission of the insert block 403 and the protrusion 404.
[0025] For example, such as Figure 1 , 2 As shown, this utility model also includes a ball screw 301 mounted in the mounting frame 3 via a bearing, a corresponding nut seat 302 sleeved around the ball screw 301, a boss 10 bolted to the bottom of the nut seat 302, a telescopic protective cover 303 sleeved around the ball screw 301 in the mounting frame 3, and a driven gear 7 bolted to the periphery of one end of the ball screw 301.
[0026] In use, the ball screw 301, nut seat 302, and boss 10 facilitate the movement of the sliding door for opening and closing. The telescopic protective cover 303 provides protection for the ball screw 301, reducing the impact of external dust on the drive structure.
[0027] For example, such as Figure 2 As shown, the present invention also includes an electric drive assembly 8 comprising a planetary reducer 801, wherein the output shaft of the planetary reducer 801 is connected to a ball screw 301, and a servo motor 802 is provided on one side of the planetary reducer 801, wherein the servo motor 802 is connected to the input end of the planetary reducer 801 via a drive shaft.
[0028] In use, the planetary reducer 801 and servo motor 802 facilitate the opening and closing of the sliding door through electric drive control. The left side plate 2 includes a controller, and the servo motor 802 is electrically connected to the controller through wires. The output shaft of the planetary reducer 801 is connected to the lead screw 301 through a coupling.
[0029] In normal operation, the controller directly drives the ball screw 301 via the servo motor 802 and planetary reducer 801. The boss 10 moves horizontally with the nut seat 302, causing the door to open and close automatically. When the electric drive fails, the conversion screw 104 is rotated, and the mounting plate 101 is pushed to slide to the right side of the plate 1 via the threaded connection. At the same time, the insert 403 is inserted into the corresponding sleeve 602, thus completing the manual control mode switch. Then, the rocker arm 601 is manually rotated, and the transmission is indirectly driven by the ball screw 301 to reciprocate through the meshing connection of the active gear and the meshing connection of the driven gear and the driven gear. This ensures that the door can still be manually opened and closed. The switching mechanism composed of the conversion screw 104, the mounting plate 101, etc., and the anti-disengagement structure such as the protrusion 404 and the limit plate 603 can ensure stable switching between the two modes and power transmission, thereby improving the reliability of the sliding door in complex scenarios.
