Description

Technical Field

[0001] This utility model belongs to the field of electric retractable gate technology, specifically relating to a front-drive power system for a frame-type retractable gate, used to provide front-drive power for a frame-type courtyard gate. Background Technology

[0002] Electric retractable gates, also known as "electric gates" or "electric folding gates," mainly consist of a gate body, a drive unit, and a control system. The gate body is made of high-quality aluminum alloy or ordinary square tubing and is mainly divided into two types: hinged and segmented. Among them, segmented electric retractable gates are more stable during use.

[0003] Existing segmented electric retractable gates are mainly formed by the sliding cooperation between the active gate and the driven gate. However, the sliding connection between the active gate and the driven gate is assisted by simple slide rails and sliders for limiting and guiding, which results in relatively large friction. Moreover, the existing structure uses chains or racks and pinions and steel cables to drive each segmented gate, making the transmission method complex.

[0004] Existing segmented electric sliding gates typically use a sliding mechanism between an active gate and a passive gate, with sliding rails and sliders engaging to achieve movement. However, this design has the following drawbacks:

[0005] High frictional resistance: The large contact area between the traditional slide rail and the slider structure results in significant friction, which not only increases the driving load but also accelerates component wear and reduces service life.

[0006] Low transmission efficiency: It relies on chains, racks, or steel cables for drive, and the transmission process is complex, which can easily lead to problems such as slippage and tooth skipping. It is particularly unstable in low temperature or humid environments.

[0007] Insufficient guiding accuracy: The existing slide rails lack dynamic adjustment function, making the door body prone to deviation or shaking, affecting the stability of operation.

[0008] High maintenance costs: Transmission components are exposed to the external environment, making them prone to dust accumulation and corrosion, requiring frequent maintenance.

[0009] The present invention aims to solve the above problems and provide a front-mounted power system for a frame-type telescopic gate that features low friction, high transmission efficiency, and strong stability. Utility Model Content
