Description
Technical Field
[0001] The utility model relates to the technical field of canopies, in particular to a telescopic electromechanical system of a telescopic canopy with a large overhang ratio. Background Art
[0002] In places such as the corridors between factories and the welcoming gates of building lobbies, canopies are built to facilitate pedestrians to pass in rainy and snowy weather. However, general canopies are fixed. While providing shelter from wind and rain, they also hinder the passage of large vehicles, especially fire trucks, making canopy buildings unable to pass fire certification. In general, because the cantilever distance of retractable canopies is too large, the movable canopy is designed to be smaller, resulting in a smaller actual shelter area and an unstable structure.
[0003] In order to solve the problem of building canopies in places where vehicles pass, especially fire trucks, a retractable electromechanical system with a large cantilever ratio retractable canopy is designed. When the movable canopy is opened, it can provide wind and rain protection for pedestrians below; when the movable canopy is closed, the vehicle passage is not blocked and large vehicles can pass freely.

[0035] The mechanical and electrical system structure of the telescopic canopy is as follows Figure 3 As shown, it includes tracks, support trolleys, dual-axis reduction motors, universal transmission shafts and sprocket chain transmission components. Two rows of tracks are arranged on the top of the fixed canopy. It is a reinforced "I"-shaped structure and uses a box beam with a corbel. The support trolley is arranged on the track to support the movement of the movable canopy. The number of sprocket chain transmission components can be freely adjusted according to the mass and area of the movable canopy. Two groups of sprocket chain transmission components are also set and fixed on the inner side of the track. The dual-axis reduction motor is fixed on the top of the fixed canopy. The two output ends transmit power to the sprocket chain transmission components on both sides through the universal transmission shaft. The chain in the sprocket chain transmission component is connected to the movable canopy through the movable canopy connection component, thereby controlling the opening and closing of the movable canopy. Buffer components are provided at the top of both ends of the two tracks to provide buffering for the movable canopy when the sliding ends. Limit switches are also provided on the sides of both ends of a track. On the running route of the support trolley, when the support trolley hits the limit switch, the stop program is triggered.
[0036] The buffer assembly is arranged at the top of the track, located at both ends of the track, and includes a mounting seat and a buffer. The mounting seat is fixed on the top of the track, and the elastic buffer is fixed on the mounting seat and located at the moving end of the movable awning. The buffer can be made of spring or rubber.

Wheels are fixed at the bottom of the frame, and the wheels are placed in the groove of the track. Guide wheels are set on both sides of the two arms of the frame. The guide wheels run along the upper side of the track. A connecting flange is fixed on the top of the frame, and the connecting flange is used to connect with the column of the movable canopy. When the movable canopy moves, due to the existence of the cantilevered section, the support trolley may switch between the two working conditions of tension or pressure. The upper and lower track surfaces in the groove can provide support for the wheels, and the guide wheels provide guidance for the movement of the support trolley.
[0038] The structure of sprocket chain transmission components is as follows Figure 5 As shown, it includes a driving sprocket, a chain support seat, a driven sprocket, a chain and an enclosure. The driving sprocket and the driven sprocket are rotatably fixed on the top of the fixed canopy. These related fixed structures are all existing technologies and will not be repeated here. The two ends of the universal transmission shaft are respectively connected to the driving sprocket, and the chain transmission connects the driving sprocket and the driven sprocket. A chain support seat is arranged under the chain, and a long key is arranged on the chain support seat to provide support for the chain. The universal transmission shaft transmits power to the driving sprocket, and the rotation of the driving sprocket drives the chain to rotate. The chain is provided with a movable canopy link assembly for linking the movable canopy. An enclosure is arranged within the movable range of the movable canopy link assembly to enclose the chain and the movable canopy connection assembly. The top of the enclosure can be used for the movable canopy link assembly to pass through and connect with the movable canopy.
