Description

Technical Field

[0001] This application belongs to the field of automatic door technology, specifically relating to a door opener and an automatic door. Background Technology

[0002] In modern buildings and various facilities, the demand for automated door control is increasing. Door openers, as devices that can automatically open and close doors according to instructions, have been widely used.

[0003] Traditional gate openers typically include a drive mechanism, a clutch, and a drive shaft connected in sequence. The clutch engages or disengages the power transmission path between the drive mechanism and the drive shaft, which is used for the transmission connection to the gate. When the clutch engages the power transmission path, the drive mechanism drives the drive shaft to rotate, thereby controlling the opening and closing of the gate. Conversely, when the clutch disengages the power transmission path, the drive mechanism cannot drive the drive shaft to rotate, thus failing to control the opening and closing of the gate.

[0004] However, currently, users mainly rely on manually operating the clutch to disconnect the power transmission path between the drive mechanism and the drive shaft. Manual operation is prone to errors, resulting in a higher incidence of safety accidents. Utility Model Content

[0005] The purpose of this application is to provide a door opener and an automatic door that can solve the problem of a high incidence of safety accidents in related technologies.

[0006] In a first aspect, embodiments of this application provide a door opener, including:

[0007] Mounting base;

[0008] The drive shaft is rotatably mounted on the mounting base;

[0009] A first drive mechanism is mounted on the mounting base;

[0010] A second drive mechanism and a clutch, wherein the second drive mechanism is mounted on the mounting base and can drive the clutch to move from a first position to a second position in a first direction;

[0011] When the clutch is in the first position, the clutch is connected to both the first drive mechanism and the drive shaft; when the clutch is in the second position, the clutch is disengaged from at least one of the first drive mechanism and the drive shaft.

[0012] Secondly, embodiments of this application also provide an automatic door, which includes a door body and the aforementioned door opener, wherein the drive shaft of the door opener is connected to the door body in a driving connection.

[0013] In this embodiment, the second drive mechanism is connected to the clutch and can drive the clutch to move from a first position to a second position in a first direction. When the clutch is in the first position, it is connected to both the first drive mechanism and the drive shaft, thus engaging the power transmission path between them. When the clutch is in the second position, it is disengaged from at least one of the first drive mechanism and the drive shaft, thus disconnecting the power transmission path between them. This means that the solution provided in this embodiment can automatically operate the clutch using the second drive mechanism to disconnect the power transmission path between the first drive mechanism and the drive shaft. Compared to manual operation, this method has a lower probability of misoperation, thereby reducing the incidence of safety accidents. Attached Figure Description

[0035] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0036] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0037] The door opener and automatic door provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0038] Please refer to Figures 1 to 11 As shown in the figure, this application provides a door opener, including: a mounting base 100, a drive shaft 200, a first drive mechanism 300, a second drive mechanism 400, and a clutch 500.

[0039] Specifically, the drive shaft 200 is rotatably mounted on the mounting base 100, and the first drive mechanism 300 is mounted on the mounting base 100. The second drive mechanism 400 is mounted on the mounting base 100 and can drive the clutch 500 to move from a first position to a second position in a first direction, for example, the first direction being... Figure 1 The direction indicated by arrow A in the diagram.

[0040] Specifically, when the clutch 500 is in the first position, the clutch 500 is connected to both the first drive mechanism 300 and the drive shaft 200. When the clutch 500 is in the second position, the clutch 500 is disengaged from at least one of the first drive mechanism 300 and the drive shaft 200. That is, the clutch 500 may be disengaged from both the first drive mechanism 300 and the drive shaft 200, or it may be disengaged from only one of the first drive mechanism 300 and the drive shaft 200.

[0041] In this embodiment, the second drive mechanism 400 is connected to the clutch 500 and can drive the clutch 500 to move from a first position to a second position in a first direction. When the clutch 500 is in the first position, it is connected to both the first drive mechanism 300 and the drive shaft 200, thus engaging the power transmission path between them. When the clutch 500 is in the second position, it is disengaged from at least one of the first drive mechanism 300 and the drive shaft 200, thus disconnecting the power transmission path between them. This means that the solution provided in this embodiment can automatically operate the clutch 500 using the second drive mechanism 400 to disconnect the power transmission path between the first drive mechanism 300 and the drive shaft 200. Compared to manual operation, this method has a lower probability of misoperation, thereby reducing the incidence of safety accidents.

[0042] In another embodiment, reference Figures 1 to 10 As shown, the door opener also includes a transmission component 600. A second drive mechanism 400 is connected to the transmission component 600 and drives the transmission component 600 to move along a first direction. The transmission component 600 has a limiting part, and the clutch 500 has a engaging part 530. The limiting part and the engaging part 530 correspond one-to-one. Along the direction from the first position to the second position, the limiting part and the corresponding engaging part 530 are sequentially arranged. When the clutch 500 is in the first position, the limiting part contacts the corresponding engaging part 530, so that the transmission component 600 drives the clutch 500 to move to the second position. The direction from the first position to the second position is, for example,... Figure 3The direction indicated by arrow B in the diagram.

[0043] In this embodiment, the transmission component 600 serves as the power transmission medium between the second drive mechanism 400 and the clutch 500. The design of the transmission component 600 makes the power transmission between the second drive mechanism 400 and the clutch 500 relatively smooth and reliable. In addition, the arrangement of the transmission component 600 makes the layout of the second drive mechanism 400 and the clutch 500 more flexible, reducing the difficulty of laying out the second drive mechanism 400 and the clutch 500.

[0044] Optionally, the transmission member 600 is, for example, a transmission plate, and the transmission member 600 is provided with a rack, the second drive mechanism 400 includes a second drive source and a transmission gear, the second drive source is connected to the transmission gear and is used to drive the transmission gear to rotate, the transmission gear meshes with the rack, thereby driving the transmission member 600 to move in the first direction, and the second drive source is, for example, a motor.

[0045] Optionally, the number of limiting parts and mating parts 530 may each be at least two. In this arrangement, the transmission member 600 and the clutch 500 are mated by at least two limiting parts and at least two mating parts 530, which makes the engagement between the transmission member 600 and the clutch 500 more reliable. Of course, the number of limiting parts and mating parts 530 may also be only one, depending on the actual needs of the design.

[0046] refer to Figure 1 and Figure 2 As shown, in actual use, the second drive mechanism 400, for example, drives the transmission component 600 to move in the direction from the first position to the second position. Simultaneously, the transmission component 600, through the limiting part and the mating part 530, drives the clutch 500 to move to the second position, thereby disconnecting the power transmission path between the first drive mechanism 300 and the transmission shaft 200. When the power transmission path between the first drive mechanism 300 and the transmission shaft 200 is disconnected, the user can manually open and close the door.

[0047] Alternatively, the user can automatically control the opening and closing of the second drive mechanism 400 via, for example, a smartphone, remote control, or control panel.

[0048] In other embodiments, the door opener may not include the transmission component 600. In this case, the second drive mechanism 400 is directly connected to the clutch 500 without the aid of other intermediate components.

[0049] In a further embodiment, reference is made to... Figures 1 to 8 as well as Figure 11As shown, the door opener also includes an operating member 810, which is mounted on the mounting base 100 and movable in a first direction. The operating member 810 is located on one side of the clutch 500, and the clutch 500 is located on the movement path of the operating member 810, so that the operating member 810 can push the clutch 500 from a first position to a second position. During the process of the operating member 810 pushing the clutch 500 to move, the distance between the mating part 530 and the limiting part in the first direction gradually increases. That is, during the process of the operating member 810 pushing the clutch 500 to move, the mating part 530 moves relative to the transmission member 600, and the mating part 530 gradually moves away from the limiting part.

[0050] In this embodiment, the user can manually operate the operating member 810 to move the operating member 810 along the first direction, which can also move the clutch 500 from the first position to the second position. During the process of using the operating member 810 to drive the clutch 500 to move to the second position, the engaging part 530 moves relative to the transmission member 600. That is to say, the position of the transmission member 600 remains unchanged, and the engaging part 530 does not drive the transmission member 600 to move. In this way, the power transmission path between the first drive mechanism 300 and the transmission shaft 200 can be manually disconnected without affecting the second drive mechanism 400.

[0051] In addition, with the solution of this embodiment, the user can either use the second drive mechanism 400 to automatically drive the clutch 500 to move to the second position, or use the operating member 810 to manually drive the clutch 500 to move to the second position. In this way, when the second drive mechanism 400 fails, the power transmission path between the first drive mechanism 300 and the transmission shaft 200 can still be disconnected manually, which improves the reliability of the door opener.

[0052] Optionally, refer to Figure 11 As shown, the door opener may also include a key 900 and a rotating member 820. The rotating member 820 is rotatably mounted on the mounting base 100, and its position in the first direction is fixed. The operating member 810 is located within the rotating member 820, and the rotating member 820 can rotate relative to the rotating member 820. Furthermore, the rotating member 820 is provided with a spiral groove 821, and the operating member 810 is provided with a limiting pin 830. One end of the limiting pin 830 passes through the spiral groove 821 and slides in cooperation with the mounting base 100 in the first direction to prevent the operating member 810 from rotating with the rotating member 820.

[0053] In actual use, the key 900 is connected to the rotating component 820. When the user rotates the key 900, the rotating component 820 rotates synchronously with the key 900. Under the cooperation of the spiral groove 821 and the limiting groove, the operating component 810 moves along the first direction with the rotation of the rotating component 820, so that the operating component 810 contacts or separates from the clutch 500. When the operating component 810 is in contact with the clutch 500, the operating component 810 can push the clutch 500 from the first position to the second position, thereby disconnecting the power transmission path between the first drive mechanism 300 and the transmission shaft 200.

[0054] It should be noted that, compared to manual operation, the method of automatically driving the clutch 500 using the second drive mechanism 400 is more efficient. In an emergency, the second drive mechanism 400 can promptly disconnect the power transmission path between the first drive mechanism 300 and the drive shaft 200.

[0055] In other embodiments, the door opener may also exclude the operating element 810, meaning that the user cannot manually drive the clutch 500 to move to the second position.

[0056] In a further embodiment, reference is made to... Figures 1 to 8 As shown, the transmission component 600 is provided with a strip-shaped hole 610, the length direction of which is the same as the first direction. The limiting part includes the end face of one end of the strip-shaped hole 610. At least a portion of the mating part 530 is located in the corresponding strip-shaped hole 610 and slides with the corresponding strip-shaped hole 610 along the first direction. In this configuration, the strip-shaped hole 610 can guide the movement of the mating part 530, making the movement of the mating part 530 more stable and smooth.

[0057] Furthermore, when the clutch 500 is in the second position, the mating part 530 engages with the end face of the other end of the slot 610 in the first direction. In this way, when the clutch 500 is in the second position, the end face of the other end of the slot 610 can restrict the mating part 530 from continuing to move, thereby improving the stability of the clutch 500.

[0058] To facilitate the distinction between the two end faces of the strip hole 610, the two end faces of the strip hole 610 are defined as the first end face 611 and the second end face 612, respectively. The limiting part includes the first end face 611. Correspondingly, when the clutch 500 is in the second position, the mating part 530 is in a limiting engagement with the second end face 612 of the strip hole 610 in the first direction.

[0059] In other embodiments, the transmission member 600 may not have the slotted hole 610. In this case, the mating part 530 and the transmission member 600 do not have a sliding fit. In this configuration, the transmission member 600 cannot guide the movement of the mating part 530. Furthermore, when the slotted hole 610 is provided, the slotted hole 610 can also be open at the position corresponding to the second end face 612. In this design, when the clutch 500 is in the second position, the mating part 530 and the slotted hole 610 do not have a limiting fit.

[0060] In a further embodiment, the mating portion 530 extends out of the slotted hole 610 and is provided with a limiting protrusion 531. The limiting protrusion 531 is located on the side of the transmission member 600 opposite to the clutch 500 and engages with the transmission member 600 in the depth direction of the slotted hole 610. With this arrangement, the limiting protrusion 531 can prevent the mating portion 530 from disengaging from the slotted hole 610 along the depth direction of the slotted hole 610, thereby making the engagement between the transmission member 600 and the clutch 500 more reliable.

[0061] Specifically, refer to Figure 10 As shown, the mating part 530 is, for example, a mating post. One end of the mating post is connected to the clutch 500, and the other end extends out of the strip hole 610 and is provided with a limiting protrusion 531. The axial direction of the mating post is the same as the depth direction of the strip hole 610.

[0062] In other embodiments, the mating part 530 may not have the limiting protrusion 531.

[0063] In another embodiment, reference Figures 1 to 8 As shown, the gate opener also includes a spring element 700, which contacts the clutch 500 and drives the clutch 500 to move from the second position to the first position. With this configuration, the spring element 700 can automatically drive the clutch 500 to move from the second position to the first position, thus saving manpower.

[0064] In other alternative embodiments, the door opener may not include the elastic element 700, in which case, for example, the clutch 500 needs to be manually driven to move from the second position to the first position.

[0065] In a further embodiment, the end face of the drive end 310 of the first drive mechanism 300 is provided with a first groove 311, the first end of the transmission shaft 200 is disposed toward the first drive mechanism 300, and the end face of the first end of the transmission shaft 200 is provided with a second groove 210. The clutch 500 includes a transmission key 520, which slides with the transmission shaft 200 or the first drive mechanism 300 in a first direction, for example, the same as the axial direction of the transmission shaft 200.

[0066] When the clutch 500 is in the first position, the two different parts of the transmission key 520 are located in the first groove 311 and the second groove 210, respectively. In this state, the drive end 310 of the first drive mechanism 300 is connected to the drive shaft 200 via the transmission key 520, and the power transmission path between the first drive mechanism 300 and the drive shaft 200 is engaged. When the clutch 500 is in the second position, the transmission key 520 disengages from either the first groove 311 or the second groove 210. In this state, the power transmission path between the transmission key 520 and either the drive end 310 of the first drive mechanism 300 or the drive shaft 200 is disconnected, thereby breaking the power transmission path between the first drive mechanism 300 and the drive shaft 200.

[0067] In this embodiment, the transmission key 520 is used to cooperate with the first groove 311 and the second groove 210 to realize the transmission connection between the drive end 310 of the first drive mechanism 300 and the transmission shaft 200. The cooperation between the transmission key 520 and the first groove 311 and the second groove 210 is relatively reliable, thereby making the operation of the door opener more reliable.

[0068] Optionally, the first drive mechanism 300 includes, for example, a first drive source and a drive shaft. The first drive source is connected to one end of the drive shaft and is used to drive the drive shaft to rotate. The other end of the drive shaft is the drive end 310 of the first drive mechanism 300, and the first drive source is, for example, a motor.

[0069] In other embodiments, the clutch 500 may also exclude the transmission key 520 and include a magnetic element. In this case, the drive end 310 of the first drive mechanism 300 may not have a first groove 311, and the first end of the transmission shaft 200 may not have a second groove 210. When the clutch 500 is in the first position, the magnetic element may magnetically engage with both the drive end 310 of the first drive mechanism 300 and the first end of the transmission shaft 200 to connect the power transmission path between the first drive mechanism 300 and the transmission shaft 200. When the clutch 500 is in the second position, the magnetic element may magnetically engage with only the drive end 310 of the first drive mechanism 300 or the first end of the transmission shaft 200 to disconnect the power transmission path between the first drive mechanism 300 and the transmission shaft 200.

[0070] In another embodiment, reference Figures 1 to 10The clutch 500 further includes an actuating member 510, which is connected to the second driving mechanism 400. The second driving mechanism 400 can drive the actuating member 510 to move in a direction from a first position to a second position. One end of the actuating member 510 is provided with a collar 5121, which surrounds at least one of the driving end 310 of the first driving mechanism 300 and the first end of the transmission shaft 200. The collar 5121 and a portion of the transmission key 520 are arranged sequentially in a direction from the first position to the second position, and the elastic member 700 is used to press the transmission key 520 against the collar 5121 so that the collar 5121 can drive the transmission key 520 to slide.

[0071] In this embodiment, the collar 5121 is arranged around at least one of the driving end 310 of the first driving mechanism 300 and the first end of the transmission shaft 200. This provides a large mating area between the collar 5121 and at least one of the driving end 310 of the first driving mechanism 300 and the first end of the transmission shaft 200, thereby improving the stability of the clutch 500. Furthermore, in this arrangement, the transmission key 520 can rotate 360 ​​degrees relative to the collar 5121, which means that the transmission shaft 200 can rotate 360 ​​degrees. This gives the transmission shaft 200 a large rotation range, thus better meeting the opening and closing requirements of the door.

[0072] Specifically, refer to Figure 3 As shown, the transmission key 520 is provided with a protrusion 522, and the collar 5121 and the protrusion 522 are arranged sequentially in the direction from the first position to the second position, and the elastic member 700 is used to press the protrusion 522 against the collar 5121.

[0073] Furthermore, the number of protrusions 522 is, for example, two, with the two protrusions 522 located on opposite sides of the transmission key 520. With this arrangement, the transmission key 520 and the collar 5121 have a larger mating area, making the fit between them more reliable. Additionally, by positioning the two protrusions 522 on opposite sides of the transmission key 520, it is beneficial to distribute the force evenly, thereby extending the service life of the transmission key 520.

[0074] In other embodiments, the actuating member 510 may not have the collar 5121. In this case, one end of the actuating member 510 may have an arc-shaped portion, which is arranged circumferentially along at least one of the driving end 310 of the first driving mechanism 300 and the first end of the transmission shaft 200. A portion of the transmission key 520 and the arc-shaped portion are arranged sequentially in the direction from the first position to the second position, and the elastic member 700 is used to press the transmission key 520 against the arc-shaped portion so as to push the transmission key 520 to slide through the arc-shaped portion.

[0075] In a further embodiment, the actuating member 510 and the mounting base 100 are slidably engaged in a first direction. In this configuration, the mounting base 100 can guide the sliding of the actuating member 510 in the first direction, thereby making the sliding of the actuating member 510 in the first direction more stable and smooth.

[0076] In other embodiments, the actuator 510 and the mounting base 100 may not have a sliding fit relationship in the first direction.

[0077] In a further embodiment, reference is made to... Figure 10 As shown, the actuating component 510 includes a first sub-part 511 and a second sub-part 512. The first sub-part 511 and the second sub-part 512 are detachably connected, and the first sub-part 511 is driven by the second drive mechanism 400. The second sub-part 512 is provided with a collar 5121. With this configuration, the first sub-part 511 and the second sub-part 512 can be machined separately, thereby reducing the machining difficulty of the actuating component 510. In addition, with this configuration, if either the first sub-part 511 or the second sub-part 512 is damaged, only the damaged one needs to be replaced, instead of replacing the entire actuating component 510, thereby reducing waste.

[0078] Optionally, refer to Figure 4 and Figure 10 As shown, the first sub-part 511 is provided with a first guide hole 5111, which is, for example, a strip-shaped structure, and the length direction of the first guide hole 5111 is the same as the first direction. The mounting base 100 is provided with a guide post 110, which is located inside the first guide hole 5111 and slides in cooperation with the first guide hole 5111 along the first direction, thereby realizing the sliding cooperation between the actuating member 510 and the mounting base 100 along the first direction. It should be noted that the first guide hole 5111 and the guide post 110 correspond one-to-one, and in this embodiment, the number of first guide holes 5111 and guide posts 110 is not limited, and can be designed according to actual needs.

[0079] Optionally, refer to Figure 10 As shown, one end of the first sub-part 511 is provided with a push plate 5112, which is positioned facing the operating member 810 and is used to contact the operating member 810. The push plate 5112 has a large area, which reduces the difficulty of the two to cooperate with the operating member 810. Furthermore, the cooperation between the push plate 5112 and the operating member 810 allows for a larger contact area between the clutch 500 and the operating member 810, thereby making the cooperation between the two more reliable.

[0080] In other embodiments, the toggle member 510 may also be an integral structure.

[0081] In a further embodiment, reference is made to... Figures 1 to 8As shown, the transmission key 520 slides in engagement with the transmission shaft 200 along a first direction. When the clutch 500 is in the second position, the transmission key 520 disengages from the first groove 311. The elastic element 700 is located inside the transmission shaft 200, and the first end of the transmission shaft 200 is sleeved outside the drive end 310 of the first drive mechanism 300. In this configuration, the elastic element 700 is hidden inside the transmission shaft 200, and the transmission shaft 200 can protect the elastic element 700, thereby extending the service life of the elastic element 700. Furthermore, in the scheme of this embodiment, the first end of the transmission shaft 200 is sleeved outside the drive end 310 of the first drive mechanism 300. In this configuration, the first end of the transmission shaft 200 and the drive end 310 of the first drive mechanism 300 can mutually limit each other, which makes the power transmission between them more stable and reliable.

[0082] Specifically, refer to Figure 6 As shown, the drive shaft 200 is provided with a guide pin 220, and the drive key 520 is provided with a second guide hole 521. The second guide hole 521 is, for example, a strip-shaped structure, and its length direction is the same as the first direction. The guide pin 220 and the second guide hole 521 are slidably engaged along the first direction, thereby realizing the slidable engagement between the drive key 520 and the drive shaft 200 along the first direction. More specifically, refer to... Figure 9 As shown, the drive shaft 200 is provided with two mounting holes 230, and the two ends of the guide pin 220 are respectively provided in the two mounting holes 230, thereby realizing the connection between the guide pin 220 and the drive shaft 200.

[0083] In other embodiments, the elastic element 700 may also be located outside the drive shaft 200. Additionally, there may be no overlay relationship between the first end of the drive shaft 200 and the drive end 310 of the first drive mechanism 300.

[0084] In one specific implementation, the door opener includes, for example, the operating member 810 and the elastic member 700 mentioned above, and the transmission member 600 includes, for example, the limiting part and the rack mentioned above. The clutch 500 includes the engaging part 530 mentioned above, and includes the actuating member 510 and the transmission key 520 mentioned above. The second drive mechanism 400 includes a second drive source and a transmission gear. The drive end 310 of the first drive mechanism 300 is provided with the first groove 311 mentioned above, and the first end of the transmission shaft 200 is provided with the second groove 210 mentioned above. The transmission key 520 slides with the transmission shaft 200 in a first direction. When the clutch 500 is in the second position, the transmission key 520 disengages from the first groove 311.

[0085] In actual use, refer to Figures 1 to 4As shown, when the door needs to be opened or closed manually, the second drive source, for example, drives the transmission gear to rotate clockwise, thereby driving the rack to move in the direction from the first position to the second position. At the same time, the rack drives the toggle member 510 and the transmission key 520 to move synchronously through the limiting part and the mating part 530, thereby causing the transmission key 520 to disengage from the first groove 311. When the transmission key 520 disengages from the first groove 311, the power transmission path between the first drive mechanism 300 and the transmission shaft 200 is disconnected, and the user can open and close the door manually.

[0086] After the door is manually opened or closed, the second drive source, such as the drive gear, rotates counterclockwise, thereby causing the rack to move in the direction from the second position to the first position. At the same time, under the drive of the elastic element 700, the transmission key 520 and the toggle element 510 reset in the direction from the second position to the first position, so that the clutch 500 returns to the first position. When the clutch 500 is in the first position, the two different parts of the transmission key 520 are respectively in the first groove 311 and the second groove 210. At this time, the power transmission path between the first drive mechanism 300 and the drive shaft 200 is engaged, and the first drive mechanism 300 can automatically drive the door to open and close.

[0087] Additionally, refer to Figures 5 to 8 As shown, when it is necessary to manually open and close the door, the clutch 500 can also be moved from the first position to the second position by operating the operating member 810. Specifically, the user can turn the key 900 clockwise to drive the operating member 810 to move in the direction from the first position to the second position. During the movement of the operating member 810 in the direction from the first position to the second position, the operating member 810 can push the toggle member 510 and the transmission key 520 to move synchronously, thereby causing the transmission key 520 to disengage from the first groove 311, so that the user can manually open and close the door.

[0088] Furthermore, after the operating member 810 moves the clutch 500 from the first position to the second position, the user can, for example, turn the key 900 counterclockwise to move the operating member 810 in the direction from the second position to the first position. At the same time, under the action of the elastic member 700, the transmission key 520 and the toggle member 510 are reset in the direction from the second position to the first position, thereby making the power transmission path between the first drive mechanism 300 and the drive shaft 200 re-engaged.

[0089] This application also provides an automatic door, which includes a door body and the aforementioned door opener, with the drive shaft 200 of the door opener being drively connected to the door body. This automatic door includes the aforementioned door opener, which has the same beneficial effects as the aforementioned door opener, and will not be described again here.

[0090] Specifically, the drive shaft 200 is connected to an output gear 240, which is connected to the door body. In actual use, the first drive mechanism 300 drives the door body to move horizontally via the output drive shaft 200 and the output gear 240, thereby opening and closing the door. In this configuration, the automatic door is, for example, a sliding door.

The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
