Abstract

The invention provides a plug-pull type top-end-driving electric sliding door mechanism and a driving method. A motor is started, the motor drives a belt to move, the belt is in engaged connection with a rotating gear through a guide wheel, the rotating gear at the bottom of a middle sliding block is driven to move, then the middle sliding block is driven to move, the middle sliding block drives aside sliding block to move, the middle sliding block is inserted into a bent upper guide rail through a guide block at the bottom, then the middle sliding block moves along a track of the upper guiderail, and then a vehicle door moves along the track of the upper guide rail to be opened; when the vehicle door is opened, the acting force of outward movement of a lower guide rail drives a swing arm outwards, so that the swing arm pulls the lower guide rail outwards; when the vehicle door is closed, a vehicle body mounting limiting block on the right side limits the right end of the lower guiderail; and by means of the structure of the upper guide rail and the lower guide rail, stability is good, noise is low, stability is good, the running track of the belt is corrected through the guidewheels at an alternating position, and double-composite movement of Y-direction movement and X-direction movement can be achieved.

Example Embodiment

[0013] In order to deepen the understanding of the present invention, the present invention will be described in further detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.
[0014] Such as Figure 1-3 As shown, this embodiment provides a plug-type top-drive electric sliding door mechanism, which includes a mounting top plate 1 on the vehicle body. The top of the mounting top plate 1 is provided with two left and right short sliding rods 2 that slide inside and outside. The rod 2 is covered with side sliders 3, and the left and right side sliders 3 are jointly provided with two long sliders 4 inside and outside for connection. The long slider 4 and the short slider 2 are set at 90°; two long sliders 4 is covered with a middle sliding block 5, the outside of the middle sliding block 5 is connected with a door mounting bracket 6, and the outside of the door mounting bracket 6 is connected with a door 7. The door 7 is located on the outer side of the mounting top plate 1 and extends downward; The motor 8, the motor 8 is connected with an endless belt 9; the top of the mounting top plate 1 is provided with two inner and outer guide wheels 10, the bottom of the middle slider 5 is provided with a rotating gear 11, and the belt 9 comes out of the motor and sequentially engages through the outer guide wheels 10 and rotates The gear 11 and the inner guide wheel 10 finally return to the motor to mesh with the motor gear to form a ring shape. The slider 5 is driven by the motor to move; the top of the mounting top plate 1 is provided with a bent upper rail 12 near the outside. A guide block is provided at the bottom of the sliding block 5, which is inserted into the upper guide rail 12 to guide; the outer end of the upper guide rail 12 is linearly and horizontally attached to the outer side of the mounting top plate 1, and the right part of the upper guide rail 12 is bent inward.
[0015] The bottom of the door 7 is provided with a lower rail 13, and the left and right sides of the lower rail 13 are provided with body mounting limit blocks 14, which limit the left and right ends when the door 7 is closed; the top of the body mounting limit block 14 on the left is movably connected with The swing arm 15 is provided with two inner and outer pulleys 16 at the top right end of the swing arm 15. The left end of the lower rail 13 is a concave arc. When the door 7 is closed, the outer pulley 16 is located at the arc, and the inner pulley 16 is located below On the inner side of the guide rail 14, when the door is opened, the lower guide rail 13 moves outward, and the outer pulley 16 moves along the arc to the inner side of the lower guide rail 13, driving the swing arm to move outward, and the swing arm pulls out the lower rail. The two pulleys 16 are attached to the inner side of the lower rail 13 to limit the position while moving.
[0016] The inner and outer ends of the short sliding rod 2 are provided with short sliding rod mounting seats 17 for mounting on the mounting top plate 1; the bottom of the motor 8 is provided with a motor bracket 18 for mounting on the mounting top plate 1.
[0017] This embodiment also provides a method for driving the electric sliding door mechanism with a plug-type top drive. First, the motor is started, the motor drives the belt to move, and the belt drives the rotating gear at the bottom of the middle slide to move, thereby driving the middle slide to move. The block drives the side slider to move. The middle slider is inserted into the bent upper rail through the guide block at the bottom, so that the middle slider moves along the track of the upper rail, and the door opens along the track of the upper rail; When the door is opened, the force of the downward movement of the lower rail drives the swing arm outward, so that the swing arm pulls the lower rail outward, and at the same time, the two pulleys on the lower swing arm fit the lower rail to fix the lower part of the door. Stability: When the door is closed, the body-mounted limit block on the right limits the right end of the lower rail.
[0018] Through the structure of the upper and lower guide rails, the above embodiments have good stability, low noise and good stability. In the alternating position, there are guide wheels to correct the running trajectory of the belt, and the double compound of Y-direction movement and X-direction movement can be realized. movement.
