Description

Technical Field

[0001] This utility model relates to the field of automatic door opening and closing technology, and specifically to improvements in the automatic door opening and closing actuator. Background Technology

[0002] With the development of technology, people are striving for automation and "freedom" in their lives and work to save manpower and resources. The field of entrance doors is also constantly developing and progressing. Currently, there are doors that can automatically open and close, such as the fully automatic door opener / closer disclosed in Chinese patent document CN108625750A for monitoring fire doors. An electric motor drives a gear-driven main arm spindle, which in turn drives the fire door to open. A separable transition gear with a detachable structure is controlled by the energization of an electromagnet to maintain its closed and open states, allowing the fire door to open and close. A main arm spindle brake stops the spindle in a fixed position when the fire door opens to a preset angle. During the opening process, the hydraulic door closing controller is pressurized to store energy for the automatic closing action, facilitating the closing of the fire door. Hydraulic oil helps to slow down the rebound speed.

[0003] In this existing technology, the actuator between the power source and the door leaf is a gear transmission method, which lacks appropriate flexibility in structure. In actual use, a door in the open state, as well as a door in the process of opening and closing, is inevitably subject to some kind of accidental pushing or squeezing, and the lack of flexibility in the actuator increases the risk of damage during these pushing and squeezing processes.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] The following is combined with Figures 1 to 9 The following describes embodiments of the present invention.

[0026] According to embodiments of the present invention, in one aspect, a reference is provided. Figure 1 An automatic opening and closing smart door includes a door opener 3 and a door closer 4 disposed between a door frame 1 and a door leaf 2. See also... Figure 2 and Figure 3 The door opener 3 has an opening bias force device 31 that applies a bias force to the door leaf 2 to tend to open, see [link to relevant documentation]. Figure 4 and Figure 5The door closer 4 has a door closing biasing force device 41 that applies a biasing force to the door leaf 2 to tend towards a closed state. (See this embodiment for details.) Figure 1 The door opener 3 is installed in the door leaf 2, and the door opener 3 is provided with a biasing force application and removal mechanism 5 (see Figure 6 The bias pressure of the opening bias pressure device 2 is applied or removed. The bias pressure of the opening bias pressure device 31 when applied is greater than that of the closing bias pressure device 41.

[0027] The opening bias pressure device 31 consists of an opening force application component 311 and an opening bias pressure component 312. The two ends of the opening bias pressure component 312 are respectively provided with the bias pressure application and withdrawal mechanism 5 and the opening force application component 311. The opening bias pressure component 312 directly applies bias pressure to the door frame 1 through the opening force application component 311.

[0028] See Figure 1 , 3 In this embodiment, the door opening force-applying component 311 is a slidingly mounted push rod, and the door opening biasing component 312 is a pressure spring, shown in the figure as a helical spring. The push rod passes through the hinged side of the door leaf 2 and is adapted to abut against the hinged side door frame 1. A return spring 313 is also provided between the push rod and the outer shell of the door opener 3, and the return spring 313 applies a biasing force to the push rod that tends to retract.

[0029] See Figure 2 , 3 In this embodiment, the door closer 4 has a base 42 mounted on the door frame 1. The lever arm of the door closing biasing device 41, which serves as the door closing force application element 411, is pivotally mounted on the base 42 via a rotating shaft 43. A torsion spring, serving as the door closing biasing element 412, is disposed around the rotating shaft 43 between the lever arm and the base 42. In this embodiment, the door closer 4 is provided with an opening angle adjustment mechanism. In this mechanism, the rotating shaft 43, serving as an adjustment and positioning mechanism, is rotatably and adjustablely mounted on the base 42. For example, internal teeth are formed on the inner wall of the mounting shaft hole of the rotating shaft 43, and corresponding external teeth are formed on the outer wall of the rotating shaft 43 at corresponding locations, allowing the internal and external teeth to mesh at different positions to achieve adjustment; or simply loosening the fastening nut of the rotating shaft 43, rotating the rotating shaft 43 to an appropriate angle, and then tightening it again to achieve adjustment. One end of the torsion spring, which is fitted on the rotating shaft 43 as a door closing biasing component 412, is connected to the lever arm, and the other end is fixedly connected to the rotating shaft 43.

[0030] See Figure 2 and Figure 6 In this embodiment, the bias pressure application and removal mechanism 5 includes a sliding push block 51 disposed in the housing of the door opener 3 and abutting against the opening bias pressure device 31; a power device 52; and a transmission mechanism 53 disposed between the sliding push block 51 and the power device 52.

[0031] In this embodiment, the power unit 52 is an electric motor, and the transmission mechanism 53 includes a driving pinion 531 mounted on the output shaft of the electric motor, a driven large gear 532 meshing with the driving pinion 531, a driven pinion 533 coaxially and synchronously connected to the driven large gear 532, and a rack 534 fixed to the sliding push block 51 and meshing with the driven pinion 533. In this embodiment, the rack 534 is directly formed on the sliding push block 51. A sliding roller 54 is provided between the sliding push block 51 and the outer shell of the door opener 3.

[0032] In this embodiment, the power unit 52 is controlled by a controller, which controls the power unit 52 to push the sliding pusher 51 to and stop at the desired position.

[0033] When the door is unlocked from the closed state, the door opener 3 receives an electrical signal command, instructing the motor 52, which serves as the power unit in the bias pressure application and release mechanism 5, to rotate forward. The motor drives the driving pinion 531 in the transmission mechanism 53, which in turn drives the driven gear 532. The driven pinion 533, which is coaxially fixed with the driven gear 532, meshes with the driven pinion 533. The driven pinion 533 drives the rack 534 to move linearly, which in turn moves the sliding push block 51 toward the force application position. The sliding push block 51 then pushes one end of the pressure spring, causing the pressure spring to generate bias pressure. The other end of the pressure spring, under the action of bias pressure, pushes the door opener 3 push rod out from the hinge side of the door leaf 2. Figure 7 Become Figure 8 The state. Furthermore, as... Figure 9 This causes the top of the push rod to act on the door frame 1, pushing the door leaf 2 open. See also Figure 4The door opening angle adjustment mechanism is illustrated by simply loosening the fastening nut of the rotating shaft 43, rotating the rotating shaft 43 to an appropriate angle, and then tightening it again. In this example, the upper end of the torsion spring, which serves as the door closing biasing component 412, is connected to the lever arm, which serves as the door closing force application component 411, and the lower end is connected to the rotating shaft 43 shown in the figure. The positioning angle of the rotating shaft 43 shown in the figure is adjusted in advance by using a wrench or screwdriver to rotate it clockwise or counterclockwise and then tightened. The rotating shaft 43, which is fixed with the torsion spring, is positioned at different angles, thereby allowing the torsion spring on the door closer 4 to obtain different elastic door closing biasing forces. During the opening of the door leaf 2, the opening biasing force acting on the top rod is greater than the closing biasing force, causing the torsion spring to deform, resulting in the closing biasing force on it becoming larger and larger. When the closing biasing force reaches a balance with the opening biasing force, the door leaf 2 is opened to the expected angle position, which is the maximum opening angle of the door leaf 2. Therefore, the smaller the initial bias force of the torsion spring, the larger the door opening angle is required to reach equilibrium. The door opener 3 can open the door to a larger maximum angle, and vice versa, thereby achieving the effect of adjustable door opening angle.

[0034] When the door opener 3 pushes the door leaf 2 open, there will be inertia. This inertia will damage the door leaf 2 and the hinges connecting the door leaf 2 and the door frame 1. At this time, the door closer 4 and the door opener 3 form a pair of reaction forces, such as Figure 4 As shown; when door leaf 2 is pushed open by door opener 3, the door body drives the sliding rod of door closer 4. The sliding rod of door closer 4 forms an angle with the door frame 1, and the return torsion spring in door closer 4 is compressed, generating a counterforce. This causes the sliding rod of door opener 3 to push door leaf 2 in the closing direction. Thus, door opener 3 and door closer 4 form a pair of reaction forces. The force of door opener 3 is greater than the force of door closer 4, so door leaf 2 will be pushed open by door opener 3 until the elastic force of the torsion spring, which acts as the closing bias pressure device 41, accumulates with deformation to a level sufficient to counteract the thrust of the pressure spring, which acts as the opening bias pressure device 31. Due to the reaction force of door closer 4, door leaf 2 can be opened gently to the required angle.

[0035] To address different door opening and closing scenarios, after door leaf 2 is positioned at a certain angle, it can maintain its opening angle or be kept open for a period of time. The working principle for maintaining the door leaf 2's opening angle is as follows: When the door is unlocked, the door opener 3 receives a signal and begins operation. The motor rotates forward, and the gear drives the rack 534 towards the push rod, causing the push rod to be pushed out by the spring. The push rod pushes door leaf 2 open to a certain angle, effectively opening the door. After the push rod extends its effective length, the sliding push block 51 stops at the desired position due to the controller's settings or received sensor signals. The push rod maintains its extended length, resting against the back frame surface of the door frame 1, thus keeping the door stationary.

[0036] After the door has been open for a certain period of time, the motor receives a closing signal or reverses according to a preset program. The gear in the transmission mechanism 53 drives the rack 534 to move back, the pressure spring changes from a compressed state to a free state, and the return spring 313 pushes the push rod back, that is, the door opener 3 retracts the push rod (e.g., Figure 6 (as shown in the state), at this time the potential energy stored in the reset torsion spring of the door closer 4 is released and acts on the door leaf 2, pushing it back, causing the door to close and lock.

[0037] In another embodiment, the door opener 3 can also be set in the door frame 1, or the door closer 4 can be set in the door frame 1 or the door leaf 2. The door opener 3 and the door closer 4 can be set together on the same side of the door leaf 2 and the door frame 1, or they can be set on two separate sides.

[0038] Regardless of the configuration of the door opener 3 and door closer 4, the bias pressure application and removal mechanism 5 can be installed in the door closer 4 to apply or remove the bias pressure of the closing bias pressure device 41. In this case, the bias pressure of the closing bias pressure device 41 when it is applied is greater than the bias pressure of the opening bias pressure device 31.

[0039] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
