Description

Technical Field

[0001] This utility model relates to the field of electric ground door technology, specifically to an electric ground door opening device. Background Technology

[0002] An electric sliding door is a door system driven by electricity, commonly used in commercial buildings, garages, warehouses, and other similar locations. It can be controlled via remote control, buttons, sensors, or intelligent systems, providing a convenient access method. An electric sliding door typically consists of a door body, track, drive system, control system, and opening device. The opening device is the core component of the electric sliding door system, responsible for controlling the opening and closing of the door. When power is available, the drive unit moves the sliding door along the track via an electric transmission device. When it reaches a predetermined position, the control system issues a command to stop the drive unit, at which point the electric sliding door is in the open or closed state.

[0003] Traditional electric ground door opening devices use a motor connected to the ground door via a belt, converting the motor's rotational motion into the door's rotational motion to open the door. However, over time, belt wear reduces transmission efficiency, causing delays in opening and closing the door and increasing maintenance costs. To address these issues, some electric ground door opening devices use a motor-driven shaft, which in turn drives the door's rotation, opening and closing the door. Shaft transmission is direct and efficient, reducing energy loss and improving transmission efficiency. It is less susceptible to external interference, maintains an accurate transmission ratio, and has fewer components, resulting in lower wear and a longer service life, thus ensuring transmission efficiency and reducing maintenance costs. However, this method requires high installation precision for the shaft transmission to ensure stability and reliability, increasing maintenance difficulty and hindering replacement operations. Therefore, a new electric ground door opening device is proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides an electric ground door opening device to solve the above-mentioned technical problems that not only increase the difficulty of maintenance, but also make replacement operations inconvenient.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an electric ground door opening device, comprising:

[0008] The door body, and the pulleys set on the surface of the door body, and toothed plates are installed on the front and back of the door body, and a support base is slidably connected to the lower surface of the door body;

[0009] A pad is positioned directly above the support base and is inserted into the support base. Drive motors are evenly mounted on the upper surface of the pad, and a rotating shaft is coaxially connected to the rotating end of the drive motor. A limit block is installed at the bottom end of the rotating shaft.

[0010] The driven wheel is located on the upper surface of the support base and meshes with the toothed plate. A transmission wheel meshes with the outer side of the driven wheel, and a driving wheel meshes with the outer side of the transmission wheel. A limit groove is provided at the rotating end of the driving wheel. When the pad is connected to the support base, the limit block of the rotating shaft is inserted into the limit groove of the driving wheel. The drive motor drives the driving wheel on the pad via the rotating shaft. The driving wheel drives the transmission wheel, which in turn drives the driven wheel. The toothed plate drives the door according to the direction of rotation of the driven wheel. The two sets of door bodies move towards each other along the support base via pulleys and are electrically opened. On the one hand, the pad can be separated from the support base to replace the driving wheel, transmission wheel, driven wheel, toothed plate, and drive motor, which not only reduces the difficulty of maintenance but also facilitates replacement. On the other hand, corresponding grooves can be provided on the inner wall of the parking garage. When the door bodies move towards each other, they move into the corresponding grooves, thus avoiding the door bodies occupying space at the entrance of the parking garage and affecting the passage of vehicles.

[0011] Preferably, a supporting top plate is added to the upper surface of the door, and connecting seats are installed around the top perimeter of the supporting top plate. The door is connected to the basement wall through the connecting seats of the supporting top plate.

[0012] Preferably, both the support base and the support top plate have sliding grooves on their surfaces, and the sliding grooves are slidably connected to the pulleys. When the two sets of door panels move towards each other along the support base, the pulleys move along the sliding grooves.

[0013] Preferably, support columns are installed around the upper surface of the support base, and the support columns are inserted into the pad. The support columns have a convex design. When the pad is inserted into the support base, the upper part of the support column is inserted into the pad.

[0014] Preferably, each of the support columns is equipped with a threaded post at its top, and the upper surface of the support column extends upward through the outer wall of the pad. When the upper part of the support column moves upward through the bottom of the pad, the threaded post is positioned on the upper surface of the pad.

[0015] Preferably, the threaded post has a threaded cap on its surface, and the cap fits tightly against the upper surface of the pad. When the threaded post is located on the upper surface of the pad, the threaded connection between the cap and the post not only ensures the stability of the connection between the pad and the support base, but also facilitates the assembly and disassembly of the pad and the support base.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides an electric ground door opening device, which has the following features:

[0018] Beneficial effects:

[0019] This electric parking door opening device connects the pad plate to the support base, allowing the limiting block of the rotating shaft to be inserted into the limiting groove of the drive wheel. The drive motor drives the drive wheel via the rotating shaft on the pad plate. The drive wheel drives the transmission wheel, which in turn drives the driven wheel. The toothed plate moves the door body according to the direction of the driven wheel, causing the two sets of door bodies to move towards each other along the support base via pulleys, thus performing an electric opening operation. When the pad plate is separated from the support base, the drive wheel, transmission wheel, driven wheel, toothed plate, and drive motor can be replaced. This not only reduces the difficulty of maintenance but also facilitates replacement operations. Furthermore, corresponding grooves can be made on the inner wall of the parking garage. When the door bodies move towards each other, they move into the corresponding grooves, thus preventing the door bodies from occupying space at the parking garage entrance and affecting the passage of vehicles.
