Description

Technical Field

[0001] The utility model relates to the technical field of door leaf driving, in particular to a double-leaf automatic door structure. Background Art

[0002] Generally, the two doors of the existing double-leaf automatic doors are of the same size, so that the two doors can be directly driven by the same motor to move synchronously in two directions to achieve opening and closing. However, when the two doors are of different sizes, they can only be driven by two different motors to achieve the effect of driving the two doors to open and close synchronously. However, the solution of using two motors for driving has relatively high requirements for the dimensional consistency of the two doors. When the sizes of the two doors cannot be the same due to factors such as space, two different motors must be used for driving, which easily leads to an increase in equipment cost and installation difficulty.

[0003] Therefore, in order to solve the problems of high cost and difficult installation existing in the existing technical solution of using two motors to drive two doors with inconsistent sizes to open and close synchronously, this patent proposes a double-leaf automatic door structure. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a double-leaf automatic door structure, which can achieve the technical effect of driving two doors with inconsistent sizes to open and close synchronously only by one motor, facilitating equipment installation and being beneficial to saving equipment space and cost.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0007] The motor, the driving shaft, and the first synchronous pulley assembly are connected in sequence. The first synchronous pulley assembly is connected to the second synchronous pulley assembly through the first synchronous belt, and the second synchronous pulley assembly is connected to the driven shaft;

[0008] The first synchronous pulley assembly is connected to the first door leaf through the second synchronous belt, and the second synchronous pulley assembly is connected to the second door leaf through the third synchronous belt;

[0009] The ratio of the diameters of the synchronous pulleys between the first synchronous pulley assembly and the second synchronous pulley assembly is inversely proportional to the ratio of the widths between the first door leaf and the second door leaf.

[0010] Preferably, the first synchronous pulley assembly includes a first synchronous pulley and a second synchronous pulley, and the first synchronous pulley and the second synchronous pulley are connected by the drive shaft;

[0011] The second synchronous pulley assembly includes a third synchronous pulley and a fourth synchronous pulley, and the third synchronous pulley and the fourth synchronous pulley are connected by the driven shaft;

[0012] The first synchronous pulley is connected to the third synchronous pulley by the first synchronous belt, the second synchronous pulley is connected to the first door leaf by the second synchronous belt, and the fourth synchronous pulley is connected to the second door leaf by the third synchronous belt.

[0013] Preferably, there are two second synchronous pulleys and two fourth synchronous pulleys, which are symmetrically arranged on both sides of the first door leaf and the second door leaf respectively.

[0014] Preferably, two first door leaf fixing plates are symmetrically arranged on both sides of the first door leaf, and two second door leaf fixing plates are symmetrically arranged on both sides of the second door leaf.

As a result, the first door leaf and the second door leaf can be simultaneously opened and closed and aggregated under the drive of one motor, that is, the technical effect of driving two doors with different sizes to open and close synchronously through only one motor is achieved. By eliminating the second motor, it is convenient for equipment installation and is beneficial to saving equipment space and cost. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figure 1-2 shown, a double-leaf automatic door structure provided by the present invention includes a motor 1, a drive shaft 2, a driven shaft 3, a first synchronous pulley assembly 4, a second synchronous pulley assembly 5, a first synchronous belt 6, a second synchronous belt 7, a third synchronous belt 8, a first door leaf 9, and a second door leaf 10;

[0024] The motor 1, the drive shaft 2, and the first synchronous pulley assembly 4 are connected in sequence. The first synchronous pulley assembly 4 is connected to the second synchronous pulley assembly 5 through the first synchronous belt 6, and the second synchronous pulley assembly 5 is connected to the driven shaft 3;

[0025] The first synchronous pulley assembly 4 is connected to the first door leaf 9 through the second synchronous belt 7, and the second synchronous pulley assembly 5 is connected to the second door leaf 10 through the third synchronous belt 8;

[0026] The ratio of the diameters of the synchronous pulleys between the first synchronous pulley assembly 4 and the second synchronous pulley assembly 5 is inversely proportional to the ratio of the widths between the first door leaf 9 and the second door leaf 10.

[0027] Specifically, as Figure 1As shown, when the motor 1 is powered on, the drive shaft 2 rotates, driving the synchronous pulley in the first synchronous pulley assembly 4 to rotate, and then driving the first synchronous belt 6 and the second synchronous belt 7 to move. The first synchronous belt 6 drives the second synchronous pulley assembly 5 to rotate, the second synchronous belt 7 drives the first door leaf 9 to move downward, the second synchronous pulley assembly 5 drives the third synchronous belt 8 to move, and the third synchronous belt 8 drives the second door leaf 10 to move upward. By driving the first door leaf 9 to move with the second synchronous belt 7 and driving the second door leaf 10 to move with the third synchronous belt 8, where the moving directions of the first door leaf 9 and the second door leaf 10 are opposite, the first door leaf 9 and the second door leaf 10 approach and converge with each other to achieve the closing of the door leaf.

[0028] Because the ratio of the diameters of the symmetrically positioned synchronous pulleys between the first synchronous pulley assembly 4 and the second synchronous pulley assembly 5 is inversely proportional to the ratio of the widths between the first door leaf 9 and the second door leaf 10. For example, when the ratio of the width of the first door leaf 9 to the second door leaf 10 is 2:1, the ratio of the diameters between the symmetrically positioned synchronous pulleys between the first synchronous pulley assembly 4 and the second synchronous pulley assembly 5 also needs to be set to 1:2. Among them, the synchronous pulleys in the first synchronous pulley assembly 4 and the second synchronous pulley assembly 5 are of the same type of gear, and the size specifications of the synchronous pulleys in the first synchronous pulley assembly 4 are all the same, and the size specifications of the synchronous pulleys in the second synchronous pulley assembly 5 are all the same, that is, the number of teeth of the synchronous pulleys in the first synchronous pulley assembly 4 is twice that of the synchronous pulleys in the second synchronous pulley assembly 5.

[0029] At this time, because the first synchronous belt 6 connects the first synchronous pulley assembly 4 and the second synchronous pulley assembly 5, according to the relationship that the tooth ratio is inversely proportional to the speed ratio, the rotational speed of the synchronous pulley in the first synchronous pulley assembly 4 is 2 times that of the synchronous pulley in the second synchronous pulley assembly 5, the rotational speed of the drive shaft 2 is 2 times that of the transmission shaft, and the moving speed of the second synchronous belt 7 is 2 times that of the third synchronous belt 8, that is, the translation speed of the first door leaf 9 is 2 times that of the second door leaf 10. Because the width of the first door leaf 9 is 2 times that of the second door leaf 10, the first door leaf 9 and the second door leaf 10 can be synchronously gathered and closed and separated and opened.

[0030] In this embodiment, by setting the ratio of the diameters of the synchronous pulleys between the first synchronous pulley assembly 4 and the second synchronous pulley assembly 5 to be equal to the ratio of the widths between the first door leaf 9 and the second door leaf 10, the ratio of the driving speed of the first synchronous pulley assembly 4 to the width of the first door leaf 9 can be made equal to the ratio of the driving speed of the second synchronous pulley assembly 5 to the width of the second door leaf 10, so that the first door leaf 9 and the second door leaf 10 can be simultaneously opened and simultaneously closed and aggregated under the drive of one motor 1, that is, the technical effect of driving two doors with different sizes to be synchronously opened and closed by only one motor 1 is achieved. By eliminating the second motor, it is convenient for equipment installation and is beneficial to saving equipment space and cost.

[0031] In an alternative embodiment, as Figure 1 , 2 shown, the first synchronous pulley assembly 4 includes a first synchronous pulley 41 and a second synchronous pulley 42, and the first synchronous pulley 41 and the second synchronous pulley 42 are connected by a drive shaft 2;

[0032] The second synchronous pulley assembly 5 includes a third synchronous pulley 51 and a fourth synchronous pulley 52, and the third synchronous pulley 51 and the fourth synchronous pulley 52 are connected by a driven shaft 3;

[0033] The first synchronous pulley 41 is connected to the third synchronous pulley 51 by a first synchronous belt 6, the second synchronous pulley 42 is connected to the first door leaf 9 by a second synchronous belt 7, and the fourth synchronous pulley 52 is connected to the second door leaf 10 by a third synchronous belt 8.

[0034] Specifically, the first synchronous pulley 41 and the second synchronous pulley 42 have the same diameter, and the third synchronous pulley 51 and the fourth synchronous pulley 52 have the same diameter.

[0035] The drive shaft 2 drives the first synchronous pulley 41 and the second synchronous pulley 42 to rotate. The first synchronous pulley 41 drives the third synchronous pulley 51 to rotate through the first synchronous belt 6. The second synchronous pulley 42 drives the second synchronous belt 7 to rotate, thereby driving the first door leaf 9 to move. The third synchronous pulley 51 drives the fourth synchronous pulley 52 to rotate through the driven shaft 3, and the fourth synchronous pulley 52 drives the third synchronous belt 8 to rotate, thereby driving the second door leaf 10 to move.

[0036] In an alternative embodiment, as Figure 1 , 2 shown, two second synchronous pulleys 42 and two fourth synchronous pulleys 52 are provided and are symmetrically arranged on both sides of the first door leaf 9 and the second door leaf 10 respectively.

[0037] Specifically, by symmetrically arranging the second synchronous pulley 42 and the fourth synchronous pulley 52 on both sides of the first door leaf 9 and the second door leaf 10, it is beneficial to ensure the rotational balance of the second synchronous pulley 42 and the fourth synchronous pulley 52, thereby ensuring the smooth movement of the first door leaf 9 and the second door leaf 10.

[0038] In an alternative embodiment, as Figure 2 shown, two first door leaf fixing plates 11 are symmetrically provided on both sides of the first door leaf 9, and two second door leaf fixing plates 12 are symmetrically provided on both sides of the second door leaf 10. The first door leaf 9 is connected to the second synchronous belt 7 through the first door leaf fixing plate 11, and the second door leaf 10 is connected to the third synchronous belt 8 through the second door leaf fixing plate 12.

[0039] Specifically, by symmetrically arranging two first door panel fixing plates 11 and two second door panel fixing plates 12 on both sides of the first door leaf 9 and both sides of the second door leaf 10 respectively, the door panel fixing plates are used to fixedly connect the door leaves, which is beneficial to fixing the door leaves and can ensure the stability of the movement of the door leaves through the fixing plates on both sides of the door leaves.

[0040] In an alternative embodiment, a first fixed bearing 13 is provided on the driving shaft 2, and a second fixed bearing 14 is provided on the driven shaft 3. There are two first fixed bearings 13, which are symmetrically arranged on both sides of the first door panel, and there are two second fixed bearings 14, which are symmetrically arranged on both sides of the second door panel.

[0041] Specifically, by symmetrically arranging the first fixed bearing 13 and the second fixed bearing 14, it is beneficial to ensure the smooth rotation of the driving shaft 2 and the driven shaft 3, and can play a role in fixedly installing the driving shaft 2 and the driven shaft 3, which is beneficial to preventing accidents.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
