AI Technical Summary
The traditional medium-straight wire-type electric sliding door of the wire is easily broken due to the sliding friction between the wire and the inner wall of the guide rail, which cannot meet the life requirements of the OEM.
By installing tension springs at both ends of the middle guide rail, the two ends of the wire rope are fixed at both ends of the middle guide rail, so that the wire rope remains tight, and the winding plate is driven to rotate through the planetary reduction motor, which drives the wire rope to shorten and release simultaneously to avoid friction between the wire rope and the inner wall of the guide rail.
During the process of opening and closing the door, the wire rope and the middle guide rail remain relatively stationary, avoiding frictional damage, extending the service life of the wire rope, and meeting the life requirements of the OEM.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of traffic equipment, in particular to a middle guide rail steel wire type electric sliding door. Background Art
[0002] At present, most of the electric sliding doors on the market are electric sliding doors with middle guide rail steel wire solutions. This type of electric sliding door is adopted by more and more modification markets due to its simple structure, easy installation, and few changes to the original car. However, this traditional steel wire solution is a closed-loop structure, with the drive motor installed on the rear side of the car body, and steel wires are led out from both ends of the winding drum and hung on the middle guide rail guide wheel. The two sections of steel wire are close to the inner wall of the guide rail. When opening and closing the door, the two sections of steel wire will slide against the inner wall of the guide rail, so that sliding friction is generated between the steel wire and the inner wall of the guide rail. After a period of use, the steel wire rope will easily break, which can no longer meet the service life requirement of more than 35,000 times required by the main engine manufacturer. Utility Model Content
[0003] Based on this, the purpose of the utility model is to provide a middle guide rail steel wire type electric sliding door to solve the technical problems raised in the above background.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a center guide rail steel wire type electric sliding door, comprising a door body and a center guide rail installed on the body, the door body is connected to the center guide rail through a connecting mechanism, and a driving mechanism is installed on the door body, the connecting mechanism comprises a center swing arm and a guide wheel, the center swing arm is fixedly connected to the door body, the guide wheel is embedded in the center guide rail and can move left and right, the driving mechanism comprises a driving motor and a winding drum, the driving motor drives the winding drum to rotate through bevel gears, a left-end steel wire rope and a right-end steel wire rope are wound on the winding drum, the terminal end of the left-end steel wire rope is fixedly connected to the left end of the center guide rail, and the terminal end of the right-end steel wire rope is fixedly connected to the right end of the center guide rail.
[0005] Furthermore, tension springs are installed at the front end and the end portion of the middle guide rail, and the end portions of the left end steel wire rope and the right end steel wire rope are fixedly connected to the tension springs.
[0006] Furthermore, the connecting mechanism also includes an upper pulley and a lower pulley, the left end wire rope passes through the upper pulley, and the right end wire rope passes through the lower pulley.
[0007] Furthermore, the driving motor is a planetary reduction motor.
[0008] The utility model fixes the two ends of the steel wire rope to the two ends of the middle guide rail, and the two ends of the middle guide rail are equipped with tensioning springs, so that the steel wire rope is kept in a taut state. When the driving motor drives the winding drum to rotate, the steel wire ropes at the two ends are driven to shorten and release synchronously, one positive and one reverse, and the shortening and releasing strokes are always kept equal. Since the other end of the steel wire rope is fixed to the vehicle body at the end of the guide rail, the middle swing arm is forced to move with the vehicle door along the retracted end of the steel wire rope, thereby realizing electric door opening and closing actions. During the process of opening and closing the door, the steel wire rope and the middle guide rail maintain a relatively static state, thereby avoiding the risk of the steel wire being easily broken due to the friction between the steel wire rope and the middle guide rail.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0014] The following describes an embodiment of the utility model based on its overall structure.
[0015] like Figure 1-Figure 4 As shown, the utility model includes a door body 1 and a middle guide rail 2 installed on the vehicle body, the door body 1 is connected to the middle guide rail 2 through a connecting mechanism 3, and a driving mechanism 4 is installed on the door body 1, the connecting mechanism 3 includes a middle swing arm 31 and a guide wheel 32, the middle swing arm 31 is fixedly connected to the door body 1, the guide wheel is embedded in the middle guide rail 2 and can move left and right, the driving mechanism 4 includes a driving motor 41 and a winding drum 42, the driving motor 41 drives the winding drum 42 to rotate through the bevel gear 42, a steel wire rope is wound on the winding drum 42, the steel wire rope includes a left end steel wire rope 44 and a right end steel wire rope 45, the end of the left end steel wire rope 44 is fixedly connected to the left end of the middle guide rail 2, and the right end steel wire rope 45 is fixedly connected to the right end of the middle guide rail 2.
[0016] Preferably, the left and right ends of the middle guide rail 2 are both installed with tensioning springs 5, and the terminal ends of the left steel wire rope 44 and the right steel wire rope 45 are both fixedly connected to the tensioning springs 5, and the tensioning springs 5 can ensure that the left steel wire rope 44 and the right steel wire rope 45 are always in a tensioned state.
[0017] Preferably, the middle swing arm 2 is further provided with an upper pulley 33 and a lower pulley 34, the left end wire rope 44 passes through the upper pulley 33, and the right end wire rope 44 passes through the lower pulley 34, and the upper pulley 33 and the lower pulley 34 avoid the risk of the steel wire being easily broken due to the friction between the steel wire and the guide rail.
[0018] Preferably, the driving motor 41 of the utility model is a planetary reduction motor, and the planetary reduction motor is installed on the door body 1, and is converted by 90 degrees through the bevel gear 42, thereby driving the winding drum 43 to rotate, thereby realizing the manual and automatic integrated operation of the electric sliding door.
