Description

Technical Field

[0001] This invention relates to the field of lock-related technology, and in particular to a door lock with both manual and electric unlocking functions. Background Technology

[0002] In today's society, people's preference for intelligent electronic products is increasingly evident, and intelligent electronic locks are already commonplace in the market. These typically rely on electric drive mechanisms to achieve locking and unlocking functions. While intelligence brings convenience and a user-friendly experience, the lack of awareness during lock management has led to a sense of insecurity among certain groups, especially the elderly, resulting in resistance to intelligent electronic locks. To cater to the needs of different user groups, various locks with both manual and electric unlocking functions have emerged on the market. For example, the door lock assembly disclosed in Chinese Patent 201811178332.3 includes a front keyway, a rear actuator, and a latch. The latch includes a telescopic bolt. The front keyway includes a lock cylinder with a keyhole for receiving a key and an actuator. The key can be used to drive the bolt to telescopically move by manipulating the actuator. The rear actuator includes a motor, a transmission device, an actuator coupling, and a user device, with the actuator coupling and user device radially linked to the actuator. The transmission device includes a main gear with a recess, in which the drive coupling is received. A gap is provided between the recess and the drive coupling, allowing the drive coupling to rotate relative to the main gear at a certain angle. The front keyway portion also includes a numeric keypad, which can be used to engage the motor to drive the latch to extend and retract when a suitable password is provided. Thus, operation of one or more of the key, user device, or motor 80 causes the drive to change position and actuate the latch. Summary of the Invention

[0003] A detailed analysis of the door lock assembly in patent 201811178332.3 revealed significant wobbling during the rotation of the drive coupling, leading to a noticeable lack of security for the user. To address the shortcomings of existing technology, this invention proposes a door lock with both manual and electric unlocking functions, comprising a lock body and a transmission rod. The lock body has a latch for locking the door leaf, and the transmission rod is tractively connected to the latch. When the transmission rod is manually or electrically driven to rotate forward or backward, it can drive the latch of the lock body to retract or extend, thereby opening or closing the door leaf. The invention is characterized by further including a first housing, a turntable rotatably mounted on the first housing, and a rotating component. The rotation center lines of the transmission rod, turntable, and rotating component overlap, and the transmission rod is tractively connected to the rotating component. A misalignment device is provided between the turntable and the rotating component, comprising a gap area and a stop block extending into the gap area. The stop block is movable within the neutral area, and the neutral area and the stop block are selectively positioned on the turntable or rotating component. When the transmission rod is manually driven to rotate forward or backward, thereby causing the rotating component to rotate forward or backward, the neutral area provides sufficient space for the stop block to move, allowing the rotating component to rotate relative to the turntable. The system also includes a controller and a drive motor signal-connected to the controller. The drive motor drives the turntable to rotate and is fixed to the first housing. When the controller receives an opening or closing instruction signal... The device can control the drive motor to drive the turntable to rotate in the forward or reverse direction. The turntable, rotating in the forward or reverse direction, can also drive the rotating component to rotate in the forward or reverse direction with the aid of the misalignment device. The rotating component, rotating in the forward or reverse direction, further drives the transmission rod to rotate in the forward or reverse direction, thereby realizing the opening or closing of the door. It also includes a positioning component fixedly installed on the first housing. The positioning component and the turntable are respectively positioned vertically. The rotating component is arranged between the turntable and the positioning component. The turntable and the positioning component provide axial positioning for the rotating component. The turntable or the positioning component provides radial positioning for the rotating component.

[0004] According to the above technical solution, compared with the prior art, the beneficial technical effects of the present invention are as follows: Since the turntable and positioning component provide axial positioning for the rotating component, and the turntable or positioning component provides radial positioning for the rotating component, when the transmission rod is manually driven to rotate forward or backward, thereby causing the rotating component to rotate forward or backward, the turntable and positioning component greatly reduce the shaking generated by the rotating component during rotation, enabling the rotating component to rotate smoothly, thereby improving the sense of security in use.

[0005] Because of the above-mentioned features and advantages, this invention can be applied to door locks with both manual and electric unlocking functions. Attached Figure Description

[0018] The structure of a door lock with both manual and electric unlocking functions, applying the technical solution of the present invention, will be further described below with reference to the accompanying drawings. Except where explicitly stated that they are equivalent or alternative implementation schemes, the various implementation details disclosed below can be selectively applied or combined in a single embodiment even if they are not directly related or synergistic in terms of function.

[0019] like Figures 1-10 As shown, a door lock with both manual and electric unlocking functions includes a lock body 9 and a transmission rod 1. The lock body 9 is provided with a bolt 90 for locking the door leaf 100. The transmission rod 1 is tractively connected to the bolt 90. When the transmission rod 1 is manually or electrically driven to rotate in the forward or reverse direction, the transmission rod 1 can drive the bolt 90 of the lock body 9 to retract or extend, thereby realizing the opening or closing of the door leaf 100. The lock is characterized by further including a first housing 6, a turntable 4 rotatably mounted on the first housing 6, and a rotating component 2. The rotation center lines of the transmission rod 1, the turntable 4, and the rotating component 2 overlap. The transmission rod 1 is tractively connected to the rotating component 2. A misalignment device is provided between the turntable 4 and the rotating component 2. The misalignment device includes a gap area 44 and a stop block 23 extending into the gap area 44. The stop block 23 is movable within the neutral area 44. The neutral area 44 and the stop block 23 are optionally disposed on the turntable 4 or the rotating component 2. When the transmission rod 1 is manually driven to rotate forward or backward, thereby causing the rotating component 2 to rotate forward or backward, the neutral area 44 provides space for the stop block 23 to move, allowing the rotating component 2 to rotate relative to the turntable 4. The system also includes a controller (not shown) and a drive motor 88 connected to the controller. The drive motor 88 is used to drive the turntable 4 to rotate and is fixed to the first housing 6. When the controller receives an instruction to open or close the door... After the signal is displayed, the drive motor 88 can be controlled to drive the turntable 4 to rotate in the forward or reverse direction. The turntable 4, which rotates in the forward or reverse direction, can also drive the rotating part 2 to rotate in the forward or reverse direction with the help of the misalignment device. The rotating part 2, which rotates in the forward or reverse direction, further drives the transmission rod 1 to rotate in the forward or reverse direction, thereby realizing the opening or closing of the door. It also includes a positioning part 3 fixedly installed on the first housing 6. The positioning part 3 and the turntable 4 are separated vertically. The rotating part 2 is arranged between the turntable 4 and the positioning part 3. The turntable 4 and the positioning part 3 provide axial positioning for the rotating part 2. The turntable 4 or the positioning part 3 provides radial positioning for the rotating part 2.

[0020] The transmission rod 1 is connected to the latch 90, and the transmission connection between them can be varied. For example, a lever 92 (discussed below) can be used as a power transmission component. The lever 92 is connected to the transmission rod 1, and the latch 90 is driven to retract or extend via the lever 92. The retraction or extension of the latch 90 is controlled by the transmission rod 1, which can be driven in two ways: manually or electrically. In the manual mode, it can be achieved through the interaction of the key and the lock cylinder 5 (discussed below) or by manually turning the knob 70.

[0021] In this embodiment, the transmission rod 1 is connected to the rotating component 2 via a transmission connection. The specific structure for this connection can vary. For example, the rotating component 2 may have a connector, and the transmission rod 1 may have a connector hole, into which the connector is inserted. In this embodiment, the rotating component 2 has a connector hole 201, the shape of which matches the cross-sectional shape of the transmission rod 1. The transmission rod 1 passes through the connector hole 201 and is connected to the rotating component 2 via the transmission connection. Thus, when the transmission rod 1 rotates forward or backward, it can synchronously drive the rotating component 2 to rotate forward or backward. Of course, in other technical solutions, asynchronous rotation of the transmission rod 1 and the rotating component 2 does not affect the implementation of this technical solution.

[0022] The gap area 44 and the stop block 23 are selectively disposed on the turntable 4 or the rotating component 2. This means that if the gap area 44 is disposed on the turntable 4, then the stop block 23 is disposed on the rotating component 2; conversely, if the stop block 23 is disposed on the turntable 4, then the gap area 44 is disposed on the rotating component 2. The size of the gap area 44 mainly depends on the range of movement of the stop block 23 during locking and unlocking, and whether the door lock is suitable for both left and right opening doors (applicable to both left and right opening doors; similarly, when viewed from outside the door, if the fixed hinge is installed on the left side of the door leaf 100, the door lock installed on the door leaf 100 needs to be suitable for left opening doors; similarly, if the fixed hinge is installed on the right side of the door leaf, the door lock installed on the door leaf 100 needs to be suitable for right opening doors) or single-sided opening doors (applicable only to either left or right opening doors). Figure 2As shown in a), in this embodiment, the door lock is suitable for double-sided opening. An arc-shaped groove is provided on the turntable 4, the center of which passes through the rotation center line of the transmission rod 1. The central angle of the arc-shaped groove is 180±10°. The inner cavity of the arc-shaped groove forms the neutral area 44, and the stop block 23 is disposed on the rotating member 2. When the latch 90 is retracted in the open state, the stop block 23 is located in the middle position of the neutral area 44. Thus, during the unlocking process, regardless of whether the stop block 23 moves to the left or right relative to the turntable 4, the neutral area 44 provides sufficient space for the stop block 23 to move. Alternatively, in other embodiments, when the latch 90 is extended in the closed state, the stop block 23 is located in the middle position of the neutral area 44, providing sufficient space for the stop block 23 to move to the left or right during the unlocking process. If the door lock is suitable for single-side opening, the central angle of the arc-shaped groove is changed to 90±10°, and in the open or unlocked state, the stop 23 is biased at one end position on the arc-shaped groove.

[0023] In this embodiment, the turntable 4 is rotatably mounted on the first housing 6. The first housing 6 includes a first upper housing 61 and a first lower housing 62. A central hole 620 is provided in the first lower housing 62. The turntable 4 includes a drive disk 41 and a rotating shaft 42 connected below the drive disk 41. The rotating shaft 42 has a central shaft hole 420, the diameter of which is larger than the rotation diameter of the transmission rod 1. The rotating shaft 42 of the turntable 4 is rotatably mounted in the central hole 620, thus enabling the turntable 4 to be rotatably mounted on the first housing 6. One end of the transmission rod 1 passes through the central shaft hole 420 from the outside of the first housing 6 and connects to the rotating component 2. Because the diameter of the central shaft hole 420 is larger than the rotation diameter of the transmission rod 1, the transmission rod 1 cannot directly drive the turntable 4 to rotate, and the turntable 4 cannot directly drive the transmission rod 1 to rotate. The transmission mechanism between the turntable 4 and the drive motor 88 can be varied. For example, the outer edge of the drive disk 41 may have a toothed groove 43, and a pinion 46 may be mounted on the shaft extension of the drive motor 88. The drive motor 88 achieves speed reduction and drives the turntable 4 to rotate through the meshing of the pinion 46 and the toothed groove 43. The number of teeth on the pinion 46 is less than the number of teeth on the turntable 4.

[0024] The positioning element 3 is fixed and does not move with the rotation of the transmission rod 1, turntable 4, and rotating element 2. In this embodiment, the positioning element 3 has an annular body 31 with an annular hole 310. The annular body 31 is connected to the rotating element 2 and provides axial positioning for the rotating element 2 from above. It also includes a lock cylinder 5, which is positioned in the annular hole 310. The lock cylinder 5 includes a cylinder shell (not shown in the figure) and a bolt (not shown in the figure) disposed in the cylinder shell. When a valid key is inserted into the bolt and twisted forcefully, the bolt is opened and can rotate in the cylinder shell. One end of the transmission rod 1 passes through the rotating element 2 and is connected to the bolt. The bolt and the transmission rod 1 rotate asynchronously. The central angle of the asynchronous rotation range is greater than or equal to 90° but does not exceed 180° (the specific structure can adopt a structure similar to the misalignment device, which can be understood by referring to the misalignment device). The rotation center lines of the bolt, transmission rod 1, rotating element 2, and turntable 4 overlap. In this embodiment, the central angle of the asynchronous rotation range is 180°, and the transmission rod 1 can rotate 90° relative to the locking bolt in both the forward and reverse directions. Further, a rotating part groove 20 is provided at the upper end of the rotating part 2 (the insertion through hole 201 is provided on the bottom wall of the rotating part groove 20), and the annular body 31 of the positioning member 3 extends into the rotating part groove 20 and presses against the bottom wall of the rotating part groove 20, providing axial positioning for the rotating part 2 from above. A disc groove 45 is provided at the upper end of the turntable 4 (the empty area 44 is provided on the bottom wall of the disc groove 45), and the lower end of the rotating part 2 extends into the disc groove 45, achieving axial positioning in the radial and downward directions using the inner wall of the disc groove 45. Of course, in other embodiments, the positioning member 3 can also provide radial positioning for the rotating part 2.

[0025] Furthermore, a pair of horns (32, 32a) for positioning are provided on both sides of the outer side of the annular body 31 of the positioning member 3. An extension arm 22 is provided on the rotating member 2, extending into the space between the pair of horns (32, 32a). When the rotating member 2 rotates forward or backward and the extension arm 22 abuts against one of the horns, the rotating member 2 also rotates the transmission rod 1 forward or backward, thereby putting the latch 90 into a retracted or extended state. At this time, the extension arm 22 moves to a position that synchronously indicates that the latch 90 is in the retracted or extended state. The pair of horns (32, 32a) are fixed and do not move with the rotation of the transmission rod 1, the turntable 4, and the rotating member 2. While limiting the extension arm 22 with the pair of horns (32, 32a), it also affects the rotation range of the transmission rod 1 and the rotating member 2, thereby increasing the difficulty of unlocking the door lock by destructive means. The pair of ram's horns (32, 32a) are part of the positioning member 3. By fixing the positioning member 3, the pair of ram's horns (32, 32a) can be fixed, thereby simplifying the structure and installation steps of the door lock. In this embodiment, as... Figure 2 As shown in a), the door lock is suitable for double-sided opening. The central angle θ of the pair of ram's horns (32, 32a) is approximately 190°. When the bolt 90 is retracted and in the open state, the extension arm 22 is located in the middle position between the pair of ram's horns (32, 32a). After the user selects to configure the door lock as a left-opening or right-opening mode according to the application needs, under the action of the transmission rod 1 and the lock body 9, the rotation angle of the extension arm 22 is approximately 90°. The specific reasons will be discussed in detail below.

[0026] To monitor the extension and retraction state of the bolt 90, the lock also includes a matching position sensor and trigger 221. The trigger 221 is mounted on the extension arm 22. When the extension arm 22 moves to a position indicating that the bolt 90 is in a retracted or extended state, the position sensor is triggered by the trigger 221 and sends a corresponding position signal to the controller. The controller then controls the drive motor 88 to stop operating based on the position signal. The lock also includes a circuit board 8, which is positioned above the rotating member 2 and fixed to the first housing 6. The position sensor is mounted on the circuit board 8, which has a clearance hole 801. The circuit board 8 passes through the clearance hole 801 onto the annular body 31 of the positioning member 3, allowing the trigger 221 to approach the position sensor. When the lock is a single-sided opening structure (applicable only to left or right opening doors), two position sensors are used; when the lock is a double-sided opening structure (applicable to both left and right opening doors), three position sensors are used. From a top view (where "top view" can be understood as the direction of observation perpendicular to the door leaf 100 after the door lock is installed on the door leaf 100), as... Figure 2 As shown, in this embodiment, the position sensor includes a first position sensor 81, a second position sensor 82, and a third position sensor 83. The second position sensor 82 and the third position sensor 83 are symmetrically positioned on both sides of the first position sensor 81, and are arranged in front of the pair of ram horns (32, 32a). If the left-side door opening is selected, the position of the extension arm 22 is detected by the first position sensor 81 and the second position sensor 82; if the right-side door opening is selected, the position of the extension arm 22 is detected by the first position sensor 81 and the third position sensor 83.

[0027] Furthermore, such as Figure 4 and Figure 10As shown, it also includes an external module, which includes a first housing 6, a turntable 4, a rotating component 2, a positioning component 3, a circuit board 8, a lock cylinder 5, and a drive motor 88. The first housing 6 includes a first upper housing 61 and a first lower housing 62, which are interlocked to form an internal cavity 60 between them. The turntable 4, rotating component 2, positioning component 3, circuit board 8, lock cylinder 5, and drive motor 88 are housed in the internal cavity 60. The turntable 4 is rotatably mounted on the central hole 620 of the bottom plate on the first lower housing 62, the rotating component 2 is rotatably mounted on the turntable 4, and the drive motor 88 is fixed to the first upper housing 61. The first housing 6 is used to fit and install onto the outer side of the door leaf 100. The first housing 6 is also equipped with a biometric signal recognition device 84, which is electrically connected to the controller and is used to pick up unlocking commands; the first upper housing 61 is provided with a faceplate hole 610, and the pickup window of the biometric signal recognition device 84 is arranged at the faceplate hole 610. Figure 4 As shown, the rotating shaft 42 of the turntable 4 is rotatably mounted on the central hole 620 of the bottom plate of the first lower housing 62, and the lower end of the rotating member 2 extends into the groove 45 of the turntable 4 and can rotate relative to the turntable 4.

[0028] In addition to manually driving the transmission rod 1 to rotate through the cooperation of a key (not shown in the figure) and the lock cylinder 5, the present invention also proposes the following manual driving method, such as... Figure 4 As shown, the door lock also includes an inner door module, which includes a second housing 7. The second housing 7 includes a second base plate 72 and a second cover plate 71 that are interlocked together. A manual knob 70 is installed on the second cover plate 71. The manual knob 70 is throttle-connected to one end of the transmission rod 1. When the manual knob 70 is manually rotated inside the door, it can drive the transmission rod 1 to rotate in the forward or reverse direction, thereby driving the bolt 90 to retract or extend.

[0029] like Figure 11 and Figure 12As shown, to enable the manual knob 70 to remain in the position where the bolt 90 is retracted or extended, the door lock also includes a main magnetic element 73 and a secondary magnetic assembly. The main magnetic element 73 and the secondary magnetic assembly are optionally disposed on the door module or the manual knob 70. The secondary magnetic assembly includes a first magnetic element 731 and a second magnetic element 732 that can respectively magnetically pair with the main magnetic element 73. From the top view, the first magnetic element 731 and the second magnetic element 732 are arranged at intervals. The first magnetic element 731 is used to magnetically attract the main magnetic element 73 when the manual knob 70 is rotated to the position where the bolt 90 is retracted, thus holding the manual knob 70 in that position. The second magnetic element 732 is used to magnetically attract the main magnetic element 73 when the manual knob 70 is rotated to the position where the bolt 90 is extended, thus holding the manual knob 70 in that position. When the door lock has a single-sided opening structure, only one second magnetic element 732 is required. In this embodiment, when the door lock has a double-sided opening structure, it further includes a pair of second magnetic elements (732, 732a), as shown in the top view (e.g.) Figure 11 As shown), a pair of second magnetic elements (732, 732a) are located on the same straight line and are placed on both sides of the first magnetic element 731. The first magnetic element 731 is located on a straight line perpendicular to the line connecting the pair of second magnetic elements (732, 732a) and passing through the midpoint of the line. The central angle between the first magnetic element 731 and any one of the second magnetic elements 732 passing through the rotation center line of the manual knob 70 is Φ. The rotation center lines of the manual knob 70, the transmission rod 1, the turntable 4, and the rotating component 2 overlap. In this embodiment, the main magnetic component 73 is disposed on the manual knob 70, and the first magnetic element 731 and the second magnetic elements (732, 732a) are disposed on the second cover plate 71 of the inner door module. The central angle Φ between the first magnetic element 731 and any one of the second magnetic elements (732 or 732a) passing through the rotation center line of the manual knob 70 is 90°. Figure 11In the state shown, the main magnetic element 73 is magnetically attracted to the first magnetic element 731, keeping the manual knob 70 in a longitudinal position. At this time, the latch 90 is retracted. When the manual knob 70 is rotated, causing the main magnetic element 73 to rotate to the vicinity of the second magnetic element 732, the main magnetic element 73 and the second magnetic element 732 are magnetically attracted to each other, keeping the manual knob 70 in a lateral position. At this time, the latch 90 is extended. In other embodiments, it may include a pair of first magnetic elements 731. From a top view, the pair of first magnetic elements 731 are located on the same straight line and are positioned on either side of the second magnetic element 732. The second magnetic element 732 is located on a straight line perpendicular to the line connecting the pair of first magnetic elements 731 and passing through the midpoint of the line. The central angle between the second magnetic element 732 and any one of the first magnetic elements 731, passing through the rotation center line of the manual knob 70, is Φ.

[0030] like Figure 5 As shown, the lock body 9 also includes a lever 92 for retracting or extending the bolt 90, the lever 92 being connected to the transmission rod 1. The lock body 9 also includes a limiting mechanism, which can constrain the lever 92 to swing within an angle range of 0 to 10 degrees above Φ. For example, when Φ is 90°, the limiting mechanism can constrain the lever 92 to swing within an angle range of 90°, 91°, 93°, and 100°. In this embodiment, the lock body 9 also includes a lock housing 91. The limiting mechanism includes a pair of left and right limiting walls (910, 911) disposed on the lock housing 91. One end of the lever 92 is provided with a limiting protrusion 921, which extends between the pair of limiting walls (910, 911). The limiting mechanism can constrain the lever 92 to swing within an angle range of 91°. A connecting hole 901 is provided at the tail of the latch 90, and the other end of the lever 92 is inserted into the connecting hole 901, thereby driving the latch 90 to extend and retract. A handle through hole 920 is also provided on the lever 92, and the transmission rod 1 is inserted into the handle through hole 920. Thus, under the constraint of the limiting mechanism, the rotation angle range of the transmission rod 1 is also 91°, thereby limiting the rotation angle range of the manual knob 70, the rotating component 2, and the extension arm 22 connected to the transmission rod 1 to 91°, preventing them from rotating freely 180°. When it is necessary to change the door opening direction, for example, from left-opening to right-opening, the installation orientation of the lock body 9 needs to be adjusted accordingly.

[0031] like Figure 4 and Figure 12As shown, a connecting through hole 78 is provided on the second cover plate 71 of the second housing 7, and a fastening bolt (not shown in the figure) is also included. The fastening bolt is used to connect the outer door module and the inner door module together and fix them to the door leaf 100 through the connecting through hole 78. When the manual knob 70 is installed on the outer door module, it covers the connecting through hole 78. In this way, the exposure of the connecting through hole 78 can be avoided to prevent it from affecting the appearance of the door lock. A plug-in seat 79 is also rotatably provided on the second cover plate 71. The transmission rod 1 is inserted into the plug-in seat 79, and the manual knob 70 is installed on the plug-in seat 79 by a locking screw.

[0032] The following is in conjunction with the appendix Figure 2 The manual and electric locking methods of the door lock are described in detail. In this embodiment, the door lock has a left-opening structure. First, the manual locking method is described: [The text abruptly ends here, likely due to an incomplete sentence or missing information.] Figure 2 In the state shown in a), it indicates that the bolt 90 has retracted and the door lock is in the unlocked state, allowing the door leaf 100 to be opened. When the key and the lock cylinder 5 are engaged, or when the manual knob 70 drives the transmission rod 1 to rotate in the opposite direction (in the direction indicated by arrow F in figure 2a), the transmission rod 1 causes the rotating component 2 to rotate in the opposite direction. The stop block 23 moves to the left relative to the turntable 4 within the neutral area 44 as the rotating component 2 rotates. When the extension arm 22 of the rotating component 2 abuts against the horn 32a, as... Figure 2 As shown in b), the latch 90 is in the extended state, allowing the door 100 to be closed. At this time, the stop 23 does not abut against the left side wall 441 of the arc-shaped groove to drive the turntable 4 to rotate. Therefore, during this process, the turntable 4 does not obstruct the rotation of the rotating component 2. When manually driving the transmission rod 1, there is no resistance from the turntable 4, which optimizes the feel. Then, when the transmission rod 1 is driven to rotate forward by the key and the lock cylinder 5, or by the manual knob 70, the stop 23 moves to the right relative to the turntable 4 within the neutral area 44 along with the rotating component 2, resetting. Simultaneously, the transmission rod 1 drives the latch 90 to retract again, thus opening the door and returning it to the position as shown in b). Figure 2 The state in 'a'.

[0033] The electric locking method is described below: When the controller receives a closing signal, it can control the drive motor 88 to drive the turntable 4 to rotate in the opposite direction (in the direction indicated by arrow F in figure 2a). The rotating turntable 4 abuts against the stop block 23 through the right side wall 442 of the arc-shaped groove, thereby causing the rotating component 2 to rotate in the opposite direction. The rotating component 2 further causes the transmission rod 1 to rotate in the opposite direction. When the extension arm 22 of the rotating component 2 abuts against the horn 32a, as... Figure 2 As shown in c), the latch 90 is in the extended state. At this time, the trigger 221 on the extension arm 22 triggers the second position sensor 82 to send a corresponding position signal to the controller. The controller controls the drive motor 88 to stop operating according to the position signal, thereby closing the door. Then, when the controller receives the door opening indication signal, it can control the drive motor 88 to drive the turntable 4 to rotate forward. The forward-rotating turntable 4 abuts against the stop block 23 through the left side wall 441 of the arc-shaped groove, thereby causing the rotating component 2 to rotate forward. The forward-rotating rotating component 2 further causes the transmission rod 1 to rotate forward. When the trigger 221 on the extension arm 22 triggers the first position sensor 81 to send a corresponding position signal to the controller, the controller controls the drive motor 88 to stop operating according to the position signal, thereby opening the door.
