Self-adaptive drive device of trackless sliding door and door with device

Abstract

The invention relates to a self-adaptive drive device of a trackless sliding door and a door with the device. The self-adaptive drive device comprises a base; a motor; a drive shaft, wherein one end of the drive shaft is synchronously connected with a motor rotating shaft in a chain drive, belt drive or engagement manner, and the other end of the drive shaft is synchronously connected with a driven gear; a movable frame, wherein the movable frame has a degree of freedom of movement relative to the base in a plane perpendicular to the rotating axis of the drive shaft, and a guide part above the driven gear is arranged on the movable frame; a gear rack, wherein the gear rack is arranged between the driven gear and the guide part, teeth on the lower surface of the gear rack are engaged with the driven gear and the upper surface of the gear rack is in sliding, rolling or engagement fit with the guide part; a guide mechanism. The self-adaptive drive device of the trackless sliding door and the door with the device have the advantages that the door body can be enabled to automatically adapt to low or uneven parts of the ground and the phenomenon that the drive device is separated or gets stuck during transverse movement of the door body is avoided.

Description

technical field [0001] The invention relates to the technical field of translation doors, in particular to an adaptive transmission device for a trackless translation door and a door with the transmission device. Background technique [0002] Traditional electric sliding doors are usually laid with tracks on the ground. Since the tracks protrude from the ground, it will affect the passage of vehicles, and because the tracks are easily damaged by pressure, it will usually affect the normal use of the electric sliding doors. [0003] In order to solve the defects of the above-mentioned tracked translation door, a patent document with the publication number CN201280895 discloses a trackless electric linear door, the door body adopts a suspension structure, and the assembly of this door is difficult and the cost is relatively high. And because the door body is heavy, it is easy to make the door body bend and deform. Therefore, its span is small and cannot be made into a large tr...

Problems solved by technology

[0002] Traditional electric sliding doors usually lay tracks on the ground, because the tracks protrude from the ground, which will affect the passage of vehicles, and, because the tracks are easy to be damaged by pressure, usually affect the normal use of electric sliding doors

[0003] In order to solve the defects of the above-mentioned tracked translation door, a patent document with the publication number CN201280895 discloses a trackless electric linear door, the door body adopts a suspension structure, and the assembly of this door is difficult and the cost is relatively high. And because of the heavy weight of the door body, it is easy to bend and deform the door body. Therefore, its span is small and cannot be made into a large translation door.

[0004] The patent document with the publication number CN201620748 discloses a trackless translation door device, which actually sets the track on the door body. When this translation door is in use, due to the unevenness of the road surface, when it encounters a low-lying ground , the wheels of the door body are separated from the ground and cannot provide support for the door body. At this time, the gravity of the door body is supported by the track, which is easy to cause the track to be bent and deformed. The transmission device of the track and the door body will interfere with each other, which will easily cause the door body and the transmission device to separate or interfere with each other and cause jamming, making the translation door unable to work normally
