Description

Technical Field

[0001] This invention relates to the field of automatic door drive and external installation equipment, specifically to a narrow external electric door opener with a multi-directional adjustable bracket. Background Technology

[0002] With the increasing demand for automatic opening and closing of sliding doors in residential, industrial, and commercial settings, external electric door openers have become widely used because they do not require significant modifications to the internal structure of the door. Existing external door openers are typically installed on one side of the sliding door track and drive the door's reciprocating movement via an output gear that meshes with a rack and pinion mounted on the door. To facilitate component arrangement, existing equipment often places the drive motor, reduction gear, and control box side-by-side along the casing, or installs them in separate casings. This results in a large overall lateral dimension, which can lead to problems such as excessive protrusion and insufficient installation space in situations with limited installation space, such as narrow door frames, closely spaced columns, or renovations of existing buildings.

[0003] Furthermore, after the external gate opener is installed, the output gear and the gate rack need to maintain appropriate direction, height, and engagement depth. Existing fixed brackets mostly use fixed mounting holes or elongated holes for adjustment. When encountering issues such as wall tilt, column deviation, non-parallelism between the gate track and the mounting surface, or errors in rack height, compensation is usually required by adding shims, re-drilling holes, or adjusting the overall installation position, making the adjustment process quite cumbersome. While some structures using elongated holes can provide some adjustment margin, the lack of independent guiding and locking relationships means that after adjustment, the gate may still deflect, sink, or change its engagement state under the reaction force of the gate's operation, thus affecting the gate opener's installation adaptability and operational stability. Summary of the Invention

[0004] (a) Technical problems to be solved The present invention aims to solve the problems of existing external electric door openers having large lateral dimensions, insufficient adaptability to installation in narrow spaces, difficulty in separately adjusting the direction, meshing depth and height of the output gear and the door rack, and insufficient force stability after adjustment.

[0005] (II) Technical Solution To address the aforementioned technical problems, this invention provides a narrow-body external electric door opener with a multi-directional adjustable bracket, comprising a narrow-body frame, a longitudinal powertrain, a side-mounted control module, a multi-directional adjustable bracket, and an output transmission assembly. The longitudinal powertrain includes a drive motor, a coaxial reduction mechanism, and an output shaft, which are sequentially arranged along the same vertical main axis. The side-mounted control module includes a strip-shaped circuit board disposed on one side of the longitudinal powertrain, with the surface of the circuit board parallel to the side wall of the narrow-body frame.

[0006] The multi-directional adjustment bracket includes a fixed base plate, a rotating adjustment plate, a door body normal sliding plate, a vertical sliding plate, and a body mounting plate connected in sequence. The rotating adjustment plate is rotatable relative to the fixed base plate around a vertical axis; the door body normal sliding plate is movable along the door body normal direction via a first linear guide pair; the vertical sliding plate is movable along the vertical direction via a second linear guide pair; the narrow-body body is connected to the body mounting plate. An output gear is connected to the lower end of the output shaft, and the output gear meshes with a rack mounted on the sliding door body.

[0007] Furthermore, the rotating adjustment plate is rotatably connected to the fixed base plate via a vertical rotating shaft. The rotating adjustment plate is provided with an arc-shaped adjustment groove with the vertical rotating shaft as the rotation reference. An arc-shaped bearing surface is provided between the fixed base plate and the rotating adjustment plate. The angle locking component locks the rotating adjustment plate through two locking positions spaced apart along the arc direction.

[0008] Furthermore, the first linear guide pair includes two parallel first guide rails, a first guide groove that cooperates with the first guide rails, and a first locking member. The two first guide rails extend along the normal direction of the door body and are spaced apart in the vertical direction. The second linear guide pair includes two parallel second guide rails, a second guide groove that cooperates with the second guide rails, and a second locking member. The two second guide rails extend in the vertical direction and are spaced apart in the direction of door movement.

[0009] Furthermore, the fuselage mounting plate has an upper support portion and a lower support portion spaced apart in the vertical direction, and the upper and lower parts of the narrow-body fuselage are detachably connected to the upper support portion and the lower support portion, respectively. The output transmission assembly also includes an output bearing, an output shaft seal, and a protective cover. The output bearing provides rotational support for the output shaft, the output shaft seal is located at the position where the output shaft exits the narrow-body fuselage, and the protective cover is located on the outside of the output gear.

[0010] Furthermore, the present invention also includes a limit control component, which includes a controller, an opening limit detection component, a closing limit detection component, an opening trigger component, and a closing trigger component. The opening limit detection component and the closing limit detection component are fixed at a position on the narrow body or the output side, and the opening trigger component and the closing trigger component are set at corresponding positions on the sliding door or the rack.

[0011] (III) Beneficial Effects The narrow-body external electric door opener with multi-directional adjustable bracket provided by this invention has the following beneficial effects: (1) The drive motor, coaxial reduction mechanism and output shaft are arranged in sequence along the vertical main axis. The strip circuit board is arranged parallel to the side wall of the narrow body to avoid the power components and control module being arranged in the horizontal direction. This helps to reduce the horizontal space occupied by the body and improve the installation adaptability in narrow door frames, narrow passages and existing door modification scenarios.

[0012] (2) The multi-directional adjustment bracket is equipped with rotation adjustment, door body normal sliding and vertical sliding structures in sequence, so that the direction angle, meshing depth and meshing height of the output gear relative to the rack can be adjusted separately. Each adjustment degree of freedom is independent of each other, which is convenient for on-site alignment.

[0013] (3) Each adjustment direction is fixed by the corresponding locking structure after alignment, and a continuous bearing path is formed by the fixed base plate, each sliding plate and the body mounting plate, which helps to reduce the deflection or sinking caused by the door running reaction force and improve the support stability after locking.

[0014] (4) The narrow body and the mounting plate are detachably connected, and the side cover forms a lateral maintenance entrance. Inspection or replacement can be carried out while retaining the original adjustment position of the bracket, which helps to reduce the workload of later maintenance and realignment.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings. It should be noted that this embodiment is described based on the known component names, reference numerals, connection relationships, and motion relationships. The drawings are used to illustrate the relative positions and mating relationships between the components and are not intended to limit specific dimensions, angle ranges, stroke values, or material parameters that are not explicitly stated.

[0017] Please see Figures 1 to 8This embodiment provides a narrow-body external electric door opener with a multi-directional adjustable bracket, mainly used for external drive installation on sliding doors. The door opener includes a narrow-body body 100, a longitudinal power assembly 200, a side control module 300, a multi-directional adjustable bracket 400, an output transmission assembly 500, and a limit control assembly 600. The narrow-body body 100 is mounted on the outside of a wall, column, or other fixed carrier that can provide a fixed load-bearing foundation via the multi-directional adjustable bracket 400. The output transmission assembly 500 is located at the lower part of the narrow-body body 100 and forms a transmission engagement with a rack 540 mounted on the sliding door body. The limit control assembly 600 provides a stop control signal when the door reaches the opening or closing endpoint.

[0018] For ease of description, a spatial orientation reference is established based on the normal installation state of the sliding door. The direction of movement along the sliding door is defined as the X-axis, the direction perpendicular to the door's operating plane and pointing from the fixed carrier to the door is defined as the Y-axis, and the vertical direction is defined as the Z-axis. The vertical main axis of the output shaft 230 is defined as Z1. The term "door normal" in this document corresponds to the Y-axis, and "vertical" corresponds to the Z-axis. The above directions are only used to illustrate the relative positions and movement relationships of the components and do not change the actual structure of each component.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the narrow-body fuselage 100 forms a long, narrow external body extending vertically, including a main housing 110, a side cover 120, a longitudinal mounting beam 130, a control cavity partition 140, and a bottom output seat 150. The main housing 110 forms an internal mounting space for accommodating the longitudinal powertrain 200 and the side-mounted control module 300. A maintenance opening is formed on one side of the main housing 110, which is removably covered by the side cover 120, allowing maintenance personnel to access the electrical and power components inside the fuselage without completely disassembling the gate opener. The longitudinal mounting beam 130 is disposed inside the main housing 110 and extends along the Z-axis, supporting the drive motor 210 and the coaxial reduction mechanism 220. The control cavity partition 140 is disposed between the longitudinal powertrain 200 and the side-mounted control module 300 to form relatively clearly defined power installation areas and control installation areas within the limited width of the fuselage. The bottom output base 150 is located at the lower part of the main housing 110 and is used to support the output shaft 230 and its corresponding output support structure.

[0020] The longitudinal powertrain 200 includes a drive motor 210, a coaxial reduction gear 220, and an output shaft 230. The drive motor 210 is located above the coaxial reduction gear 220, with its output end connected to the input end of the coaxial reduction gear 220. The output end of the coaxial reduction gear 220 is connected to the output shaft 230. The output axis of the drive motor 210, the input and output axes of the coaxial reduction gear 220, and the output shaft 230 are arranged along the same vertical main axis Z1, ensuring that the power transmission path primarily extends along the height direction of the narrow fuselage 100, rather than running parallel along the width direction. Thus, the drive motor 210, the coaxial reduction gear 220, and the output shaft 230 together form the longitudinal powertrain 200.

[0021] The side-mounted control module 300 includes a strip circuit board 310, a mounting bracket 320, and an insulating partition 330. The strip circuit board 310 is mounted on the inner wall of the main housing 110 via the mounting bracket 320. The surface of the strip circuit board 310 is substantially parallel to the side wall of the main housing 110, and its length extends along the Z-axis. The insulating partition 330 is located between the strip circuit board 310 and the drive motor 210 and the coaxial reduction mechanism 220. With this arrangement, the side-mounted control module 300 does not need to form a separate control box laterally parallel to the drive motor 210 and the coaxial reduction mechanism 220, thus avoiding the simultaneous occupation of the machine's lateral width by the power components and control components. During maintenance, the side cover 120 can be removed to access the strip circuit board 310 and the relevant connection points of the longitudinal powertrain 200 from the side of the machine.

[0022] like Figure 3 As shown, the output transmission assembly 500 includes an output bearing 510, an output shaft seal 520, an output gear 530, and a rack 540, wherein the output shaft 230 also serves as the output component of the longitudinal power assembly 200. The output bearing 510 is disposed within the bottom output seat 150, providing rotatable support for the output shaft 230; the output shaft 230 extends downward along Z1 and exits from the lower end of the narrow body 100, with the output shaft seal 520 positioned at the exit point of the output shaft 230. The output gear 530 is fixed to the exposed end of the output shaft 230, its rotation axis coinciding with the axis of the output shaft 230, and it can rotate synchronously with the output shaft 230. The rack 540 is disposed along the moving direction of the sliding door on the side of the door facing the door opener, and the output gear 530 meshes with the rack 540. When the drive motor 210 is working, its output is transmitted to the output shaft 230 through the coaxial reduction mechanism 220. The output shaft 230 then drives the output gear 530 to rotate. The meshing of the output gear 530 and the rack 540 converts the rotational motion into linear motion of the sliding door body along the X-axis.

[0023] The bottom output base 150 is located at the lower part of the main housing 110 and is used to support the output shaft 230. A protective cover 550 is provided on the outside of the output gear 530. The protective cover 550 is fixed to the narrow body 100 and its installation position is adjusted together with the narrow body 100. The protective cover 550 is used to protect the exposed area of ​​the output gear 530. Its setting position should avoid the normal meshing area between the output gear 530 and the rack 540, so as not to affect the gear and rack transmission.

[0024] like Figures 4 to 6 As shown, the multi-directional adjustment bracket 400 is disposed between the narrow-body fuselage 100 and the fixed carrier, and includes a fixed base plate 410, a rotation adjustment plate 420, a vertical rotating shaft 430, an angle locking component 440, a door normal sliding plate 450, a first linear guide pair 460, a vertical sliding plate 470, a second linear guide pair 480, and a fuselage mounting plate 490. These components are arranged sequentially from the fixed carrier towards the narrow-body fuselage 100 to form an installation and load-bearing relationship, so that the three installation and adjustment degrees of freedom are arranged in series.

[0025] The fixing base plate 410 is used for external fixation to the wall or column surface. The fixing base plate 410 is provided with fixing holes for connection to the fixing carrier. In this embodiment, circular fixing holes distributed at the four corners of the fixing base plate 410 can be used, and fixation can be achieved by expansion bolts, chemical anchors, or mechanical fasteners compatible with the column. The fixing base plate 410 is located entirely outside the fixing carrier, and it is not required to form a dedicated embedded box inside the wall, nor is it required to form an installation cavity inside the door to accommodate the door opener.

[0026] The rotating adjustment plate 420 is rotatably connected to the fixed base plate 410 via a vertical rotating shaft 430. The vertical rotating shaft 430 is positioned along the Z-axis, allowing the rotating adjustment plate 420 to rotate relative to the fixed base plate 410 around the vertical rotating shaft 430 when the angle locking member 440 is released, without resulting in unrestrained translation along the X, Y, or Z axes. An arc-shaped adjustment groove 421 is provided on the rotating adjustment plate 420, extending in an arc shape with the vertical rotating shaft 430 as the rotation reference. An arc-shaped bearing surface 422 is provided in the area where the fixed base plate 410 and the rotating adjustment plate 420 face each other. The angle locking member 440 engages with the arc-shaped adjustment groove 421, allowing the rotating adjustment plate 420 to rotate around the vertical rotating shaft 430 in the adjustment state, and locking the rotating adjustment plate 420 to the fixed base plate 410 after adjustment.

[0027] In this embodiment, the angle locking component 440 includes two locking bolts spaced apart along an arcuate direction and a pressure plate spanning the outside of the arcuate adjustment groove 421. The two locking bolts pass through the arcuate adjustment groove 421 and are connected to the fixed base plate 410. The locking position formed by the two locking bolts and the vertical rotating shaft 430 together constitute a distributed load-bearing relationship. When the rotating adjustment plate 420 is subjected to torque generated by the narrow body 100 and the output transmission reaction force, the vertical rotating shaft 430 provides rotational support. The two angle locking positions and the arcuate bearing surface 422 jointly bear the reaction force after locking, so that the angle adjustment structure has a clear load-bearing path after alignment, instead of relying solely on a single elongated hole and a single bolt to maintain the position.

[0028] The door body normal sliding plate 450 is mounted on the rotation adjustment plate 420 via a first linear guide pair 460. The first linear guide pair 460 includes two parallel first guide rails 461, a first guide groove 462 that mates with the first guide rails 461, and a first locking member 463. The two first guide rails 461 are fixed to the side of the rotation adjustment plate 420 facing away from the fixed base plate 410, extend along the Y-axis direction, and are spaced apart in the Z-axis direction; the first guide groove 462 is located on the side of the door body normal sliding plate 450 facing the rotation adjustment plate 420, and forms a sliding fit with the corresponding first guide rail 461. In this embodiment, the first guide rails 461 and the first guide groove 462 can adopt a T-shaped guide fit that can restrict the plate from lateral disengagement from the guide direction. The first locking element 463 is located near the first linear guide pair 460. When the first locking element 463 is released, the door normal sliding plate 450 can move along the Y-axis direction. After adjustment, the door normal sliding plate 450 is locked on the rotating adjustment plate 420 by the first locking element 463.

[0029] Two first guide rails 461 are spaced apart in the vertical direction, so that the door normal sliding plate 450 does not swing freely around a single guide position, but moves along the Y-axis under the common constraint of the two distributed guide positions. Thus, the first linear guide pair 460 is mainly used to adjust the meshing depth of the output gear 530 relative to the rack 540 and to compensate for the distance deviation between the fixed carrier and the door running plane.

[0030] The vertical sliding plate 470 is mounted on the door normal sliding plate 450 via a second linear guide pair 480. The second linear guide pair 480 includes two parallel second guide rails 481, a second guide groove 482 cooperating with the second guide rails 481, and a second locking member 483. The two second guide rails 481 are fixed to the side of the door normal sliding plate 450 opposite to the rotating adjustment plate 420, extending along the Z-axis and spaced apart in the X-axis direction. The second guide groove 482 is located on the vertical sliding plate 470 and forms a vertical sliding engagement with the corresponding second guide rail 481. The second locking member 483 is used to lock the vertical sliding plate 470 onto the door normal sliding plate 450 after the height adjustment is completed. The two second guide rails 481 jointly guide the vertical sliding plate 470, limiting its lateral sway during the lifting and lowering adjustment process, allowing it to primarily retain its installation and adjustment freedom along the Z-axis direction.

[0031] The fuselage mounting plate 490 is fixed to the vertical sliding plate 470 and is used for detachable connection with the narrow-body fuselage 100. The fuselage mounting plate 490 forms mutually spaced support or connection areas in the vertical direction, so that the load of the narrow-body fuselage 100 can be transferred to the vertical sliding plate 470 through the vertically spaced connection positions, rather than being concentrated at a single cantilever connection point. When maintenance or replacement of the narrow-body fuselage 100 is required, the detachable fastening relationship between the narrow-body fuselage 100 and the fuselage mounting plate 490 can be released, and the narrow-body fuselage 100 can be moved away from the multi-directional adjustment bracket 400, while the fixed base plate 410 and each adjustment plate can remain in their original alignment position.

[0032] like Figure 7 As shown, the three installation adjustment degrees of freedom in this embodiment correspond to the three alignment requirements of the output gear 530 and rack 540, respectively. The output gear 530 and protective cover 550 participate in the above installation adjustment as a whole with the narrow body 100. First, the rotating adjustment plate 420 rotates around the vertical axis 430 to correct the angular deviation between the mounting surface of the fixed carrier and the direction of the door track, so that the extension directions of the output gear 530 and rack 540 form a suitable meshing relationship. Second, the door normal sliding plate 450 moves along the Y-axis to change the center distance between the output gear 530 and rack 540 to adjust the meshing depth. Third, the vertical sliding plate 470 moves along the Z-axis to change the vertical position of the output gear 530 to adjust the height correspondence between the output gear 530 and rack 540. The above three degrees of freedom are set independently. The Y-axis adjustment does not generate the Z-axis degree of freedom, and the Z-axis adjustment does not change the already locked angular degree of freedom.

[0033] During on-site installation, first, externally fix the base plate 410 to the wall or column, using it as a fixed reference for subsequent adjustments. Then, loosen the angle locking member 440, allowing the rotating adjustment plate 420 to rotate around the vertical axis 430. Once the narrow body 100 is adjusted to a suitable position relative to the door track, lock the angle locking member 440. Next, loosen the first locking member 463, allowing the door normal sliding plate 450 to move along the first guide rail 461, adjusting the meshing depth of the output gear 530 and rack 540. After adjustment, lock the first locking member 463. Then, loosen the second locking member 483, allowing the vertical sliding plate 470 to move up and down along the second guide rail 481 to adjust the meshing height of the output gear 530 and rack 540. Finally, lock the second locking member 483. During adjustment, it is preferable to release one degree of freedom in one direction at a time, adjust and lock it in that direction, and then adjust in the next direction to ensure that the narrow body 100 always has clear support.

[0034] The multi-directional adjustment bracket 400 can be understood as having an installation and adjustment state and a locked working state. In the installation and adjustment state, only the rotary joint or linear guide joint that needs to be adjusted is in a movable state; in the locked working state, the angle locking member 440, the first locking member 463 and the second locking member 483 are all in a locked state, and the rotary adjustment plate 420, the door body normal sliding plate 450 and the vertical sliding plate 470 no longer move relative to the fixed base plate 410. When the door opener normally opens and closes the door, the multi-directional adjustment bracket 400 is used as a fixed load-bearing structure, and the actual working movements are mainly the rotation of the output shaft 230 and the output gear 530 and the movement of the sliding door body along the X-axis.

[0035] like Figure 8 As shown, the limit control assembly 600 includes a controller 610, an opening limit detection element 620, a closing limit detection element 630, an opening trigger element 640, and a closing trigger element 650. The controller 610 is electrically connected to the drive motor 210 and is used to control the start, stop, and forward / reverse operation of the drive motor 210. The opening limit detection element 620 and the closing limit detection element 630 are fixed in positions on the narrow body 100 or the output side and remain fixed during the opening and closing of the door; the opening trigger element 640 and the closing trigger element 650 are respectively set on the sliding door body or the rack 540 at positions corresponding to the opening end point and the closing end point along the door travel direction, and move with the door body. Figure 8 The example illustrates the follow-up installation relationship of the door opening trigger 640, while the door closing trigger 650 is set at the corresponding trigger position at the other end point of the door's travel.

[0036] When the door opens, the controller 610 drives the drive motor 210 to rotate in the corresponding direction. The coaxial reduction mechanism 220 reduces the output of the drive motor 210 and increases its torque. The output shaft 230 drives the output gear 530 to rotate. The output gear 530 drives the sliding door to move in the opening direction by meshing with the rack 540. When the door moves to the opening end point, the opening trigger 640 and the opening limit detection element 620 form a trigger relationship, and the controller 610 stops the drive motor 210 accordingly. When the door closes, the controller 610 causes the drive motor 210 to run in the opposite direction. The output gear 530 drives the door to move in the opposite direction through the rack 540. When the door reaches the closing end point, the closing trigger 650 triggers the closing limit detection element 630, and the controller 610 stops the drive motor 210.

[0037] During the opening and closing process described above, the reaction force generated by the door movement is transmitted from the rack 540 to the output gear 530, and further transmitted through the output shaft 230, the coaxial reduction mechanism 220, and the internal support structure of the narrow body 100 to the mounting plate 490. The mounting plate 490 then sequentially transmits the load to the vertical sliding plate 470, the second linear guide pair 480, the door normal sliding plate 450, the first linear guide pair 460, the rotation adjustment plate 420, and the fixed base plate 410, finally transmitting it to a fixed carrier such as a wall or column. Through the above continuous load-bearing path, the installation adjustment function and the working load-bearing function are realized by the same support structure, and the output gear 530 and the rack 540 are kept in the aligned state after locking in each adjustment direction.

[0038] When maintenance of the side control module 300 or inspection of the drive motor 210 is required, the side cover 120 can be removed while the multi-directional adjustment bracket 400 is locked, and inspection can be performed through the side maintenance opening. When the entire narrow-body frame 100 needs to be replaced, the output gear 530 can be disengaged from the rack 540 or the door can be moved to a safe position. Then, the connection between the narrow-body frame 100 and the frame mounting plate 490 can be released, and the narrow-body frame 100 can be removed. Since the fixed base plate 410, the rotating adjustment plate 420, the door normal sliding plate 450, and the vertical sliding plate 470 remain in their original installation positions, the original adjustment basis for the angle, engagement depth, and engagement height can be retained after reinstalling the narrow-body frame 100 of the same specification, reducing the workload of overall realignment.

[0039] This embodiment uses the output gear 530 and rack 540 of a sliding door as a specific implementation method, focusing on the vertical integrated layout of the longitudinal power assembly 200 and the three-way series adjustment relationship of the multi-directional adjustment bracket 400. The specifications of conventional anchors used between the fixed base plate 410 and the wall or column, the specific wall thickness of the main housing 110, the actual stroke in each adjustment direction, and the angle adjustment range can be determined according to the actual installation space and load-bearing requirements. In the absence of corresponding prototype data or measurement records, this embodiment does not impose specific numerical limits on the above parameters.

[0040] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent changes or substitutions made by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope defined in the claims.
