Description

Technical Field

[0001] This utility model relates to an electric drive device for a building or vehicle, and also to an electric door having the electric drive device. Background Technology

[0002] Electric doors are increasingly widely used in production and daily life. Electric doors mainly include electric telescopic doors, electric sliding doors, and electric swing doors. Among them, electric swing doors have developed more slowly because their transmission is more complex than other electric doors. The motor and transmission system of swing electric doors are usually located in the upper and / or lower part of the door. Moreover, due to the structural limitations of the transmission system, their opening angle is often limited to within 90 degrees, making it difficult to adapt to scenarios that require the door leaf to be opened at a larger angle. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an electric transmission device with a simple structure and a large-angle movable transmission component.

[0004] This utility model provides an electric drive device, comprising:

[0005] The motor has a drive wheel mounted on its power output shaft.

[0006] At least one driven wheel, which is driven to rotate by the power transmitted from the driving wheel;

[0007] The first transmission component has a first end and a second end. The first end is sleeved on the transmission shaft, which is driven to rotate by the driven wheel.

[0008] The second transmission component has a first end and a second end, the first end being rotatably connected to the second end of the first transmission component, and the second end being rotatably connected to the door leaf or door frame.

[0009] With the above structure, the first and second transmission components are in an extended state when the door is open and in a folded state when the door is closed. Taking the door frame with an electric transmission device as an example, the motor transmits power to the drive wheel through the power output shaft. The rotation of the drive wheel drives the driven wheel to rotate, which in turn drives the first end of the first transmission component to rotate. The first transmission component moves, causing the first end of the second transmission component to rotate, which in turn moves the second end of the second transmission component to drive the door to rotate. By setting the drive wheel and the driven wheel, the rotating and cooperating first and second transmission components have flexible rotation angles and movement positions, thereby increasing the door opening and closing angle range and meeting the needs of more usage scenarios.

[0010] Furthermore, the second end of the second transmission component is rotatably connected to a connecting seat, which is fixed to the door leaf or door frame, and the second end of the second transmission component is connected to the connecting seat through a second pin.

[0011] Furthermore, the second end of the first transmission component is connected to the first end of the second transmission component via a first pin.

[0012] Furthermore, the second end of the first transmission member has a first connecting ear and a second connecting ear, which are provided with pin holes for mounting a first pin.

[0013] Furthermore, the second end of the first transmission member bends toward the first end of the second transmission member.

[0014] Furthermore, it also includes a transmission box, which includes an upper connecting part, a lower connecting part, and a bending part. The upper connecting part, the lower connecting part, and the bending part form a space that can accommodate the first transmission component and the second transmission component. The second transmission component can extend out of the space when it moves. The lower connecting part has mounting holes for mounting the driving wheel and the driven wheel, and the lower connecting part is also provided with a shaft hole.

[0015] This utility model also provides an electric door with the above-mentioned electric drive device, wherein at least one electric drive device is mainly disposed in the door frame or at least one electric drive device is mainly disposed in the door leaf.

[0016] Furthermore, it also includes at least one hinge, which includes a first rotating seat and a second rotating seat that are rotatably connected. The first rotating seat includes a first connecting end and a second connecting end, and a third pin is disposed between the first connecting end and the second connecting end. The second rotating seat has a leaf plate, which is connected to the first rotating seat by the third pin.

[0017] Furthermore, an accommodating space is provided between the first connecting end and the second connecting end, and the page plate is bent in a "C" shape, with one end of the page plate connected to the first rotating seat being accommodated in the accommodating space.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0030] This utility model provides an electric door, including a door leaf 10, a door frame 11, and an electric drive device connecting the door leaf 10 and the door frame 11. Figure 1 The image shows an electric door equipped with an electric drive device, which works in conjunction with two hinges 9.

[0031] As an improved embodiment, refer to the appendix. Figure 2 and 6 , Figure 2 The extension state of the electric drive device when door 10 is open is shown. Figure 6 The diagram illustrates the folded state of the electric drive device when the door 10 is closed. The electric drive device includes a motor 1, with a drive wheel 31 mounted on the power output shaft 2 of the motor 1. When the power output shaft 2 rotates, the drive wheel 31 rotates. It also includes a driven wheel 32, which meshes with the drive wheel 31. The driven wheel 32 is driven to rotate by the power transmitted from the drive wheel 31. If necessary, multiple meshing driven wheels can be sequentially arranged between the driven wheel 32 and the drive wheel 31. Power is transmitted from the drive wheel 31 to the meshing driven wheels, and then sequentially transmitted by each stage of driven wheels until it is transmitted to the drive shaft 4. The first end of the first transmission member 51 is mounted on the drive shaft 4. When the drive shaft 4 is driven to rotate, the first end of the first transmission member 51 rotates, causing the second end of the first transmission member 51 to rotate and move around the drive shaft 4. The first end of the second transmission member 52 is rotatably connected to the second end of the first transmission member 51. Preferably, the second end of the first transmission member 51 is connected to the first end of the second transmission member 52 via a first pin 71. Therefore, when the second end of the first transmission member 51 moves, it drives the first end of the second transmission member 52 to rotate and move, thereby driving the second end of the second transmission member 52 to rotate and move, which in turn drives the door leaf 10 to rotate.

[0032] With the aforementioned electric drive device, the first transmission component 51 and the second transmission component 52 are in an extended state when the door leaf 10 is open and in a folded state when the door leaf 10 is closed. Taking the door frame 11 with the motor 1 as an example, when the door leaf 10 is opened from closed, the motor 1 outputs power through the power output shaft 2 to drive the first transmission component 51 to rotate outward, which in turn drives the second transmission component 52 to rotate outward. The second transmission component 52 can rotate out of the door frame 11, so as to drive the door leaf 10 to achieve a larger angle of rotation, thereby increasing the opening and closing angle range of the door leaf 10 and meeting the needs of more usage scenarios. When the door leaf 10 is closed from open, the motor 1 outputs power through the power output shaft 2 to drive the first transmission component 51 to rotate inward, which in turn drives the second transmission component 52 to rotate inward until the second transmission component 52 retracts into the door frame 11 to achieve a tight closure of the door leaf 10. The motor 1 can be powered by a battery or an external power source. The battery can be installed together with the motor 1 in the door frame 11 or the door leaf 10. The external power source can be connected to the power supply through wiring inside the door frame 11 or the door leaf 10. In addition, most of the electric drive mechanism is located inside the door frame or door leaf and is not exposed. This not only facilitates the maintenance of the parts, but also makes the electric door more concise and beautiful overall.

[0033] As an improved embodiment, the electric door is provided with a connecting seat 6, which is fixed to the door leaf 10 or the door frame 11. The fixing position of the connecting seat 6 varies depending on the fixing position of the motor 1 of the electric drive device. Specifically, if the motor 1 is fixed to the door frame 11, the connecting seat 6 is fixed to the door leaf 10, and vice versa. The connecting seat 6 can be integrally formed with the door leaf 10 or the door frame 11, or it can be a detachable component. The second end of the second transmission member 52 is rotatably connected to the connecting seat 6. Preferably, the second end of the second transmission member 52 is connected to the connecting seat 6 through a second pin 72. When the door leaf 10 is opened and closed, the second transmission member 52 can rotate around the second pin 72.

[0034] As an improved embodiment, refer to the appendix. Figure 4 The second end of the first transmission member 51 has a first connecting ear 511 and a second connecting ear 512. The first connecting ear 511 and the second connecting ear 512 are provided with pin holes to install the first pin 71. The first end of the second transmission member 52 is installed between the first connecting ear 511 and the second connecting ear 512 through the first pin 71, which can reduce the installation volume and facilitate the folding of the first transmission member 51 and the second transmission member 52.

[0035] As an improved embodiment, refer to the appendix. Figure 4 , 6The second end of the first transmission member 51 bends toward the first end of the second transmission member 52, forming an "L" shape. When the door 10 is closed, the second transmission member 52 can rotate into the "L"-shaped enclosed space, allowing the first transmission member 51 and the second transmission member 52 to fold better and further reduce the folding volume.

[0036] As an improved embodiment, refer to the appendix. Figure 3 The aforementioned electric door also includes a transmission box 8, which comprises an upper connecting part 82, a lower connecting part 83, and a bending part 84. The upper connecting part 82, the lower connecting part 83, and the bending part 84 form a space that can accommodate the first transmission component 51 and the second transmission component 52. The second transmission component 52 can extend out of the space when it moves. The lower connecting part 83 has mounting holes for mounting the driving wheel 31 and the driven wheel 32, and also has a shaft hole 81 for the transmission shaft 4 to pass through. The transmission box 8 is dustproof and moisture-proof, protecting the internal components.

[0037] As an improved embodiment, the aforementioned electric door typically uses two hinges 9 in conjunction with the electric drive mechanism to connect the door frame and the door leaf (depending on actual needs, one or more electric drive mechanisms may be configured with one, two, three, or four hinges 9, etc.). See attached document. Figure 5 The hinge 9 includes a first rotating seat and a second rotating seat that are rotatably connected to each other. The first rotating seat includes a first connecting end 91 and a second connecting end 92, and a third pin 94 is disposed between the first connecting end 91 and the second connecting end 92. The second rotating seat has a leaf plate 93, which is connected to the first rotating seat via the third pin 94. The hinge 9 can be installed in two ways: the first rotating seat is connected to the door frame 11 and the second rotating seat is connected to the door leaf 10, or the first rotating seat is connected to the door leaf 10 and the second rotating seat is connected to the door frame 11.

[0038] Preferably, the hinge 9 has a C-shaped leaf plate 93. A receiving space is provided between the first connecting end 91 and the second connecting end 92 of the first rotating seat. When the hinge 9 is closed, the end of the leaf plate 93 connected to the first rotating seat can rotate into the receiving space. The C-shaped arrangement of the leaf plate 93 allows it to rotate without being restricted by the corners of the door frame 11 or the door leaf 10. When the hinge 9 is open, the corners enter the arc-shaped space of the C-shape and do not abut against the hinge 9, thereby increasing the opening angle of the hinge 9.

[0039] The above embodiment mainly takes the example of setting the motor 1 in the electric drive device in the door frame 11 and setting the connecting seat 6 connected to the second transmission component 52 in the door leaf 10. In practice, the motor 1 can be set in the door leaf 10 and the connecting seat 6 connected to the second transmission component 52 can be fixed in the door frame 11, which can also realize the electric opening and closing of the door leaf 10.

[0040] Unless otherwise specified, the materials, reagents, and experimental equipment involved in this embodiment of the utility model are all commercially available products in the field of electric doors and windows.

[0041] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make improvements and modifications without departing from the core technology of this utility model, and such improvements and modifications should also fall within the patent protection scope of this utility model. Any changes within the meaning and scope equivalent to the claims of this utility model should be considered as included within the scope of the claims.
