Description

Technical Field

[0001] This utility model relates to the technical field of door panel accessories, and in particular to a bottom beam profile and door panel. Background Technology

[0002] Electric retractable gates (also known as electric gate panels) mainly consist of a gate body, a drive unit, and a control system. The gate body is generally made of aluminum alloy profiles, and it is flexible and has a large extension range. It is widely used as a movable fence in various industrial and mining plants, workshops, warehouses, machine rooms, garages, and other occasions.

[0003] For example, patent document CN201821651988.8 discloses a bottom beam profile, belonging to the technical field of electric door accessories. It includes a main frame with a guide support cavity at the bottom. On the upper first side of the main frame, from top to bottom, there are sequentially arranged a top cavity for the circulating chain, a straight chain cavity, a drive wheel cavity, a bottom cavity for the circulating chain, and a meshing support bar cavity; the bottom cavity for the circulating chain and the meshing support bar cavity are located in the same cavity. A side guide cavity is provided on the upper second side of the main frame. This technical solution not only supports the electric door but also, in conjunction with a transmission device, enables it to move while simultaneously outputting power, achieving power transmission between different bottom beam levels, thereby realizing trackless operation of the electric door.

[0004] The above technical solution still has the problem of structural complexity. This is because its power transmission components are split, so different cavities need to be formed on the bottom beam profile to accommodate different power transmission components. However, for gates with integrated power transmission components, using the above bottom beam profile will result in redundant cavities, which will not make the best use of the materials. At the same time, this complex bottom beam profile will also increase production costs. Utility Model Content

To this end, this utility model proposes a bottom beam profile that can be adapted for use with gates having integrated power transmission components, and has a simple, reliable, and durable overall structure, effectively reducing production costs while ensuring structural strength.

The first side long side and the second side long side are spaced apart. The middle connecting side is connected between the first side long side and the second side long side. One end of the top side and the first bottom surrounding side are respectively connected to the top and bottom of the first side long side. The other end of the top side is connected to the side surrounding side. The second bottom surrounding side is connected to the bottom of the second side long side. There are gaps between the first bottom surrounding side and the second bottom surrounding side, as well as between the side surrounding side and the second side long side.

[0008] The first side long side, the middle connecting side, the second side long side, the first bottom surrounding side, and the second bottom surrounding side together form a first receiving cavity; the first side long side, the middle connecting side, the top side, the side surrounding side, and the second side long side together form a second receiving cavity.

[0015] According to some embodiments of this utility model, both the first side long side and the second side long side are vertically arranged.

[0016] According to some embodiments of this utility model, both the top edge and the middle connecting edge are horizontally arranged.
