Description

Technical Field

[0001] The utility model relates to the technical field of elevator doors, in particular to an arc-shaped closed elevator door machine device. Background Art

[0002] With the increasing diversity of architectural styles and people's increasing demands for architectural aesthetics, traditional straight-opening door elevators have a relatively simple and ordinary appearance, which makes it difficult to meet the needs of some high-end commercial buildings, luxury hotels, modern art venues, etc. for elevators with a unique and modern appearance. These venues often want elevators to be an important element in the building, giving people a novel and high-end visual experience, but the traditional straight-opening door design has obvious shortcomings in this regard.

[0003] Traditional elevator doors mostly use a straight-open design, requiring a large space to fully open for smooth entry and exit of passengers and cargo. This can lead to significant space occupation in some space-constrained locations, such as small elevator shafts in renovated older buildings, or in specialized environments requiring a compact layout. Fully opening straight-open doors can significantly impact traffic efficiency and overall space utilization. To address this issue, we propose a curved-closing elevator door operator.

[0009] Preferably, the servo motor is electrically connected to an external single chip microcomputer and an external power supply.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. The curved door is connected to the fixed frame through a rotating shaft and a fixed plate. The rotating shaft can rotate on the fixed frame. The curved door is installed in a sliding groove opened on one side of the elevator body and can slide in it, which provides a basic motion track for the opening and closing of the curved door.

[0012] 2. The servo motor starts working after receiving the signal, and its output end drives the threaded rod to rotate. Since the threaded rod and the sliding block are threadedly connected, the sliding block will move linearly along the guide rod. An adjustment rack is fixedly connected to one side of the sliding block, and the gears between the adjustment rack and the transmission wheel are engaged with each other. When the sliding block moves, the adjustment rack will move accordingly, thereby driving the transmission wheel to rotate.

[0020] In an optional embodiment, the rotating shaft 208 is fixedly connected to a synchronous wheel 209 on the upper side of the fixed frame 201, and an auxiliary wheel 206 is symmetrically provided on one side of the elevator body 1 close to the fixed frame 201. An auxiliary belt 205 is sleeved on the auxiliary wheel 206 and the synchronous wheel 209, and a sliding member 203 is symmetrically provided on one side of the curved door 202, and the sliding member 203 is located on the auxiliary belt 205.

[0021] The curved door 202 is connected to the fixed frame 201 through a rotating shaft 208 and a fixed plate 204. The rotating shaft 208 can rotate on the fixed frame 201. The curved door 202 is installed in a sliding groove 207 opened on one side of the elevator body 1 and can slide therein, which provides a basic motion track for the opening and closing action of the curved door 202. At the same time, a synchronous wheel 209 is fixedly connected to the upper side of the fixed frame 201 on the rotating shaft 208. Auxiliary wheels 206 are symmetrically arranged on one side of the elevator body 1 close to the fixed frame 201. An auxiliary belt 205 is sleeved between the synchronous wheel 209 and the auxiliary wheel 206. The sliding member 203 symmetrically arranged on one side of the curved door 202 is located on the auxiliary belt 205, which enables the movement of the curved door 202 to be coordinated with the movement of the auxiliary belt 205.

[0022] In an optional embodiment, the rotating shaft 208 is fixedly connected to a transmission wheel 210 on the lower side of the fixed frame 201, and a mounting seat 211 is symmetrically provided on one side of the fixed frame 201, and a threaded rod 213 is movably connected between the mounting seats 211, and the mounting seat 211 is fixedly connected to a guide rod 216 on one side of the threaded rod 213, and a sliding block 214 is threadedly connected to the threaded rod 213, and the sliding block 214 is located on the guide rod 216, and a servo motor 212 is embedded in one side of the mounting seat 211, and the output end of the servo motor 212 is fixedly connected to the threaded rod 213.

[0023] In an optional embodiment, an adjustment rack 215 is fixedly connected to one side of the sliding block 214 , and the adjustment rack 215 and the transmission wheel 210 are meshed with each other.

[0024] In an optional embodiment, the servo motor 212 is electrically connected to an external microcontroller and an external power supply;

[0025] The servo motor 212 starts working after receiving the signal, and its output end drives the threaded rod 213 to rotate. Since the threaded rod 213 and the sliding block 214 are threadedly connected, the sliding block 214 will make a linear motion along the guide rod 216. An adjustment rack 215 is fixedly connected to one side of the sliding block 214. The gears between the adjustment rack 215 and the transmission wheel 210 are engaged with each other. When the sliding block 214 moves, the adjustment rack 215 will move accordingly, thereby driving the transmission wheel 210 to rotate. The rotation of the transmission wheel 210 will drive the rotating shaft 208 connected thereto to rotate. Because the rotating shaft 208 is fixedly connected to the arc door 202 through the fixed plate 204, the arc door 202 will slide in the sliding groove 207 as the rotating shaft 208 rotates.

[0026] The working principle of the present utility model is as follows: when using the device, the arc door 202 is connected to the fixed frame 201 through the rotating shaft 208 and the fixed plate 204, the rotating shaft 208 can rotate on the fixed frame 201, the arc door 202 is installed in the sliding groove 207 opened on one side of the elevator body 1, and can slide therein, which provides a basic motion track for the opening and closing action of the arc door 202. At the same time, a synchronous wheel 209 is fixedly connected to the upper side of the fixed frame 201 on the rotating shaft 208, and an auxiliary wheel 206 is symmetrically provided on one side of the elevator body 1 close to the fixed frame 201. An auxiliary belt 205 is sleeved between the synchronous wheel 209 and the auxiliary wheel 206, and a sliding member 203 symmetrically provided on one side of the arc door 202 is located on the auxiliary belt 205, which makes the movement of the arc door 202 able to cooperate with the movement of the auxiliary belt 205.

[0027] The servo motor 212 starts working after receiving the signal, and its output end drives the threaded rod 213 to rotate. Since the threaded rod 213 and the sliding block 214 are threadedly connected, the sliding block 214 will make a linear motion along the guide rod 216. An adjustment rack 215 is fixedly connected to one side of the sliding block 214. The gears between the adjustment rack 215 and the transmission wheel 210 are engaged with each other. When the sliding block 214 moves, the adjustment rack 215 will move accordingly, thereby driving the transmission wheel 210 to rotate. The rotation of the transmission wheel 210 will drive the rotating shaft 208 connected thereto to rotate. Because the rotating shaft 208 is fixedly connected to the arc door 202 through the fixed plate 204, the arc door 202 will slide in the sliding groove 207 as the rotating shaft 208 rotates.
