Description

Technical Field

[0001] This invention relates to the field of lock technology, and more particularly to a smart lock. Background Technology

[0002] In related technologies, smart locks have an external knob for manual control of opening and closing. If the manual transmission system of the knob and the driven gear transmission system driven by the motor are coaxial, a clutch mechanism needs to be added between the two transmission systems to prevent the motor from rotating in the opposite direction when manually opening and closing the lock, which would cause greater resistance. Therefore, the driven gear of the smart lock needs to rotate in one direction according to the actual situation to achieve engagement and disengagement with the manual transmission system. Generally, when a smart lock is to be compatible with both left-opening and right-opening door types (when the smart lock is installed on a left-opening door, i.e., on the right side of the door, the lock body extends the bolt to the right; when the smart lock is installed on a right-opening door, i.e. on the left side of the door, the lock body extends the bolt to the left), it cannot automatically detect whether it is installed on a left-opening or right-opening door, making it difficult to determine the correct rotation direction of the knob sleeve to achieve the purpose of extending and retracting the bolt for opening and closing the lock. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a smart lock that can automatically detect whether it is installed on a left-opening or right-opening door, and can determine the correct rotation direction of the knob sleeve to achieve the purpose of extending and retracting the bolt for locking and unlocking.

[0004] According to an embodiment of the present invention, a smart lock includes: a lock body assembly including a bolt, the lock body assembly having a first installation state in which the bolt extends to the left and a second installation state in which the bolt extends to the right; a lock cylinder assembly connected to the lock body assembly and rotatable to drive the bolt to extend or retract; a drive assembly including a drive device and a knob sleeve, the knob sleeve being connected to the lock cylinder assembly, the drive device being used to drive the knob sleeve to rotate and switch between a first stop position for extending the bolt and a second stop position for retracting the bolt; a first sensor capable of switching a trigger state with the rotation of the knob sleeve; and a controller being used to acquire a resistance signal from the drive device and to determine the installation state of the lock body assembly based on the resistance signal and the trigger state of the first sensor.

[0005] The smart lock according to embodiments of the present invention has at least the following beneficial effects: When the smart lock is in a first installation state, the drive device rotates along a preset direction, stopping the knob sleeve at one of a first stopping position and a second stopping position. When the smart lock is in a second installation state, the drive device also rotates along the preset direction, but stops the knob sleeve at another stopping position. A first sensor can switch between different triggering states depending on whether the knob sleeve rotates to the first stopping position or the second stopping position. The controller can detect whether the knob sleeve is located at the first stopping position or the second stopping position based on the triggering state of the first sensor. The drive device generates a resistance signal when the knob sleeve is stopped, allowing the controller to determine that the knob sleeve has been stopped. Therefore, based on whether the knob sleeve is ultimately stopped at the first stopping position or the second stopping position, the controller can detect whether the smart lock is in the first installation state or the second installation state, and then set the direction of the subsequent drive device driving the knob sleeve to rotate according to the installation state, so as to achieve the purpose of unlocking and closing the lock.

[0006] According to some embodiments of the present invention, the drive assembly further includes a transmission member, the drive device is connected to the transmission member, the transmission member has a first direction and a second direction for rotation, and the smart lock is configured such that: when the controller determines that the smart lock is in the first installation state, the controller controls the transmission member to rotate along the first direction to switch the knob sleeve from the first stop position to the second stop position, and to rotate along the second direction to switch the knob sleeve from the second stop position to the first stop position; when the controller determines that the smart lock is in the second installation state, the controller controls the transmission member to rotate along the second direction to switch the knob sleeve from the first stop position to the second stop position, and to rotate along the first direction to switch the knob sleeve from the second stop position to the first stop position.

[0007] According to some embodiments of the present invention, the knob sleeve has a knob sleeve rotation angle when switching between the first stop position and the second stop position, and the smart lock is configured such that when the knob sleeve is in the first stop position or the second stop position, the controller controls the transmission member to rotate in the opposite direction, and the reverse rotation angle of the transmission member is greater than or equal to the knob sleeve rotation angle and less than or equal to the angle value of 360° minus the knob sleeve rotation angle.

[0008] According to some embodiments of the present invention, the rotation angle of the knob sleeve is configured to be 90°, and the reverse rotation angle of the transmission member is selected from the range of 90° to 270°.

[0009] According to some embodiments of the present invention, a first lever protrudes from the side edge of the knob sleeve, and a second lever corresponding to the first lever protrudes from the side of the transmission member near the knob sleeve. The second lever rotates with the transmission member to push the first lever to rotate, and the second lever can rotate with the transmission member to separate from the first lever.

[0010] According to some embodiments of the present invention, both the first and second paddles are configured as fan-shaped paddles, the fan-shaped paddles having a sector angle of 90° in the rotation direction; the transmission member is configured to achieve the gradual rotation of the second paddle by gradually rotating, the transmission member rotating at an angle of 90° per step.

[0011] According to some embodiments of the present invention, the knob sleeve has a 90° rotation angle when switching between the first stop position and the second stop position; the smart lock further includes a second sensor electrically connected to the controller, the second sensor being configured as four, the four second sensors being distributed sequentially at 90° intervals along the circumference of the transmission member, the four second sensors being used to detect the position of the transmission member.

[0031] The following is a reference appendix. Figures 1 to 4 The smart lock 100 provided in this application is described in detail.

[0032] like Figures 1 to 4 As shown, the smart lock 100 of this embodiment includes: a lock body assembly 110, including a bolt 111, the lock body assembly 110 having a first installation state in which the bolt 111 extends to the left and a second installation state in which the bolt 111 extends to the right; a lock cylinder assembly 120, connected to the lock body assembly 110, capable of rotating to drive the bolt 111 to extend and retract; a drive assembly, including a drive device 130 and a knob sleeve 131, the knob sleeve 131 being connected to the lock cylinder assembly 120, the drive device 130 being used to drive the knob sleeve 131 to rotate and switch between a first stop position where the bolt 111 extends and a second stop position where it retracts; a first sensor 140, capable of switching trigger states with the rotation of the knob sleeve 131; and a controller, used to acquire the resistance signal of the drive device 130 and to determine the installation state of the lock body assembly 110 based on the resistance signal and the trigger state of the first sensor 140.

[0033] The smart lock 100 according to an embodiment of the present invention has at least the following beneficial effects: When the smart lock 100 is in a first installation state, the drive device 130 rotates along a preset direction, stopping the knob sleeve 131 at one of a first stopping position and a second stopping position. When the smart lock 100 is in a second installation state, the drive device 130 also rotates along the preset direction, but stops the knob sleeve 131 at another stopping position. The first sensor 140 can switch between different triggering states according to the knob sleeve 131 rotating to the first stopping position and the second stopping position. The controller can detect whether the knob sleeve 131 is located at the first stopping position or the second stopping position according to the triggering state of the first sensor 140. The drive device 130 is used to generate a resistance signal when the knob sleeve 131 is stopped, so that the controller can determine that the knob sleeve 131 has been stopped. Therefore, depending on whether the knob sleeve 131 is ultimately stopped at the first stop position or the second stop position, the controller can detect whether the smart lock 100 is in the first installation state or the second installation state. Then, based on the installation state, the direction of rotation of the knob sleeve 131 driven by the subsequent drive device 130 can be set to achieve the purpose of opening and closing the lock.

[0034] It should be noted that, in this embodiment of the invention, when the smart lock 100 is installed on a left-opening door, that is, on the left side of the door, the lock body of the smart lock 100 extends the latch 111 to the left, and the smart lock 100 is in the first installation state; while when the smart lock 100 is installed on a right-opening door, that is, on the right side of the door, the lock body of the smart lock 100 extends the latch 111 to the right, and the smart lock 100 is in the second installation state.

[0035] Reference Figure 2 The knob sleeve 131 can rotate to form a rotation path, and the knob sleeve 131 can rotate clockwise and counterclockwise along this rotation path. Optionally, in some exemplary embodiments, the first abutment position is located at the upper end of the rotation path, while when the smart lock 100 is in the first installation state, the second abutment position is located at the left end of the rotation path; when the smart lock 100 is in the first installation state, the second abutment position is located at the right end of the rotation path.

[0036] Furthermore, in embodiments of the present invention, reference is made to... Figures 2 to 4 Regardless of whether the smart lock 100 is in the first installation state or the second installation state, the controller first presets a rotation direction and controls the drive device 130 to drive the knob sleeve 131 to rotate along that rotation direction. For example:

[0037] The controller can set the clockwise direction of the rotation path of the knob sleeve 131 as the initial rotation direction of the knob sleeve 131, and the knob sleeve 131 is driven to rotate clockwise. If the knob sleeve 131 is finally stopped at the first stopped position, the controller can detect that the smart lock 100 is in the first installation state. Afterward, the controller can set the locking and unlocking method based on this detection result, including controlling the drive device 130 to drive the knob sleeve 131 to rotate clockwise to unlock (retracting the bolt 111) and controlling the drive device 130 to drive the knob sleeve 131 to rotate counterclockwise to lock (extending the bolt 111). If the knob sleeve 131 is finally stopped at the second stopped position, the controller can detect that the smart lock 100 is in the second installation state. Afterward, the controller can set the locking and unlocking method based on this detection result, including controlling the drive device 130 to drive the knob sleeve 131 to rotate counterclockwise to unlock (retracting the bolt 111) and controlling the drive device 130 to drive the knob sleeve 131 to rotate clockwise to lock (extending the bolt 111).

[0038] It should be noted that, in this embodiment of the invention, the knob sleeve 131 switches between the first stop position and the second stop position by rotating from the first stop position to the second stop position in one direction, and then rotating back from the second stop position to the first stop position in the opposite direction, and so on, in a reciprocating cycle.

[0039] In this embodiment of the invention, the first sensor 140 is used to detect whether the knob sleeve 131 is in a first abutment position or a second abutment position. For example, when the knob sleeve 131 is rotated to the first abutment position, the first sensor 140 can switch to a first trigger state, and the controller can determine that the knob sleeve 131 is in the first abutment position based on the first trigger state; when the knob sleeve 131 is rotated to the second abutment position, the first sensor 140 can switch to a second trigger state, and the controller can determine that the knob sleeve 131 is in the second abutment position based on the second trigger state.

[0040] According to some embodiments of the present invention, the drive assembly further includes a transmission member 132, and the drive device 130 is connected to the transmission member 132. The rotation of the transmission member 132 has a first direction and a second direction. The smart lock 100 is configured such that: when the controller determines that the smart lock 100 is in a first installation state, the controller controls the transmission member 132 to rotate in the first direction to switch the knob sleeve 131 from a first stop position to a second stop position, and to rotate in the second direction to switch the knob sleeve 131 from a second stop position to a first stop position; when the controller determines that the smart lock 100 is in a second installation state, the controller controls the transmission member 132 to rotate in the second direction to switch the knob sleeve 131 from a first stop position to a second stop position, and to rotate in the first direction to switch the knob sleeve 131 from a second stop position to a first stop position.

[0041] In this way, the controller can set the subsequent locking and unlocking methods according to the installation status of the smart lock 100.

[0042] Reference Figures 2 to 4 In this embodiment of the invention, the transmission component 132 and the knob sleeve 131 are coaxially arranged. The driving device 130 can drive the transmission component 132 to rotate, and the transmission component 132 can drive the knob sleeve 131 to rotate. The rotation of the transmission component 132 forms the rotation path of the transmission component 132.

[0043] For example, in one embodiment, the clockwise direction of the transmission member 132 along the rotation path is the first direction, and the counterclockwise direction is the second direction. When the controller determines that the smart lock 100 is in the first installation state, the controller controls the transmission member 132 to rotate counterclockwise, so that the knob sleeve 131 switches from the first stop position to the second stop position, thus enabling the smart lock 100 to be locked in the first installation state; the controller controls the transmission member 132 to rotate clockwise, so that the knob sleeve 131 switches from the second stop position to the first stop position, thus enabling the smart lock 100 to be unlocked in the first installation state.

[0044] When the controller determines that the smart lock 100 is in the second installation state, the controller controls the transmission component 132 to rotate counterclockwise, so that the knob sleeve 131 switches from the second stop position to the first stop position, thus enabling the smart lock 100 to be unlocked in the first installation state; the controller controls the transmission component 132 to rotate clockwise, so that the knob sleeve 131 switches from the first stop position to the second stop position, thus enabling the smart lock 100 to be locked in the second installation state.

[0045] It should be noted that when the knob sleeve 131 is initially located in the first stop position, the second stop position, or any position between the first stop position and the second stop position, the rotation of the transmission member 132 can also rotate the knob sleeve 131 to the first stop position or the second stop position.

[0046] According to some embodiments of the present invention, the knob sleeve 131 switches between a first stop position and a second stop position to have a knob sleeve 131 rotation angle. The smart lock 100 is configured such that when the knob sleeve 131 is in the first stop position or the second stop position, the controller controls the transmission member 132 to rotate in the opposite direction. The reverse rotation angle of the transmission member 132 is greater than or equal to the rotation angle of the knob sleeve 131 and less than or equal to the angle difference between 360° and the rotation angle of the knob sleeve 131.

[0047] In this way, the transmission component 132 can rotate in the opposite direction by a sufficient angle after the knob sleeve 131 is rotated to the position, thus avoiding the knob sleeve 131 rotating in the opposite direction without being obstructed by the transmission component 132.

[0048] Specifically, refer to Figure 2 In this embodiment, the knob sleeve 131 reciprocates and can switch between the first stop position and the second stop position. It can be understood that after the knob sleeve 131 is rotated to the correct position, the controller controls the transmission component 132 to rotate in the opposite direction by an angle value. For example, the transmission component 132 drives the knob sleeve 131 to rotate clockwise to the first stop position, at which point the smart lock 100 unlocks. Then, the transmission component 132 is driven by the driving device 130 to rotate counterclockwise to retract by an angle value. In particular, in order to avoid the knob sleeve 131 being resisted by the transmission component 132 during the process of rotating counterclockwise from the second stop position to the first stop position when the user manually locks the door, the reverse rotation angle of the transmission component 132 is greater than or equal to the rotation angle of the knob sleeve 131. At the same time, in order to avoid the transmission component 132 directly driving the knob sleeve 131 due to an excessively large reverse rotation angle, the reverse rotation angle of the transmission component 132 is less than or equal to the angle difference between 360° and the rotation angle of the knob sleeve 131.

[0049] According to some embodiments of the present invention, the rotation angle of the knob sleeve 131 is configured to be 90°, and the reverse rotation angle of the transmission member 132 is selected from the range of 90° to 270°.

[0050] It is understandable that this configuration aligns with users' everyday habits of using locks. For instance, the smart lock 100 unlocks when the user rotates the knob vertically and locks when the knob is rotated 90° to the left to a horizontal position. Therefore, configuring the knob sleeve 131 to rotate at 90° is a preferred implementation. In other embodiments, the knob sleeve 131 can be configured to rotate at other angle values.

[0051] Reference Figures 2 to 4 According to some embodiments of the present invention, a first lever 133 is formed protruding from the side edge of the knob sleeve 131, and a second lever 134 corresponding to the first lever 133 is formed protruding from the side of the transmission member 132 near the knob sleeve 131. The second lever 134 rotates with the transmission member 132 to push the first lever 133 to rotate, and the second lever 134 can rotate with the transmission member 132 to separate from the first lever 133.

[0052] In this way, the transmission component 132 can drive the knob sleeve 131 to rotate.

[0053] It is understood that rotating the transmission component 132 causes the second lever 134 to rotate. After the second lever 134 abuts against the first lever 133, it can push the first lever 133 to rotate together, thereby driving the knob sleeve 131 to rotate. When the knob sleeve 131 is rotated to its position, the drive device 130 can drive the transmission component 132 to rotate in the opposite direction to separate the second lever 134 from the first lever 133, thus achieving the resistance of the second lever 134 when the first lever 133 rotates in the opposite direction. Furthermore, the second lever 134 extends towards the side where the knob sleeve 131 is located and abuts against the first lever 133. The second lever 134 is formed protrudingly on the surface of the transmission component 132, which avoids the need to open a groove in the transmission component 132 to set the second lever 134 and can strengthen the structural strength of the transmission component 132.

[0054] Reference Figure 3 and Figure 4 According to some embodiments of the present invention, the first lever 133 and the second lever 134 are both configured as fan-shaped levers, and the fan-shaped levers have a fan angle of 90° in the rotation direction; the transmission member 132 is configured to realize the gradual rotation of the second lever 134 by gradually rotating, and the angle of each step of the transmission member 132 is 90°.

[0055] It is understood that this configuration allows the first toggle 133 and the second toggle 134 to rotate to match the rotation angle (90°) of the knob sleeve 131 when switching between the first stop position and the second stop position. For example, the rotation path of the second toggle 134 and the first toggle 133 can be divided into a first module, a second module, a third module, and a fourth module with sequentially arranged equal angle values. When the knob sleeve 131 switches from the first stop position to the second stop position, the second toggle 134 rotates 90° from the first module to the second module along the rotation path, and pushes the first toggle 133 to rotate 90° from the second module to the third module, thereby enabling the knob sleeve 131 to rotate from the first stop position to the second stop position. Of course, this design is not limited to this. In other embodiments, the sector angle can also be configured to other angle values, as long as the sum of the sector angle values ​​of the first toggle 133 and the second toggle 134 is greater than 90° and less than 270°.

[0056] Reference Figure 2 According to some embodiments of the present invention, the knob sleeve 131 switches between a first stop position and a second stop position and has a rotation angle of 90°; the smart lock 100 also includes a second sensor 160 electrically connected to the controller, the second sensor 160 being configured as four, the four second sensors 160 being distributed sequentially at 90° intervals along the circumference of the transmission member 132, the four second sensors 160 being used to detect the position of the transmission member 132.

[0057] In this way, the transmission component 132 can be precisely controlled to rotate back at least 90°, thereby avoiding the resistance of the transmission component 132 when the knob sleeve 131 is opened or closed by the user.

[0058] Because the knob sleeve 131 switches between its stop positions by 90° each time, the transmission component 132 needs to rotate at least 90° to avoid creating resistance to the reverse rotation of the knob sleeve 131. It can be understood that the four sensors can achieve 360° omnidirectional detection of the transmission component 132's position. Therefore, the sensors' detection of the transmission component 132's position is unaffected by its initial position. It should be noted that the initial position of the transmission component 132 should be understood as the position of the transmission component 132 after the knob sleeve 131 is driven to rotate to the first or second stop position. The distribution of the four sensors corresponds to the first and second stop positions, ensuring that regardless of the location of the first and second stop positions, the four sensors 160 can detect whether the transmission component 132 has rotated back at least 90°.

[0059] Reference Figure 3 and Figure 4 According to some embodiments of the present invention, the four second sensors 160 are all configured as four photoelectric switches 161 fixedly disposed outside the transmission member 132. The transmission member 132 is provided with a stop 163 corresponding to the photoelectric switch 161. The controller is configured such that the stop 163 triggers one of the photoelectric switches 161 to obtain position information.

[0060] In this way, the second sensor 160 can detect the position of the transmission component 132.

[0061] Specifically, the four photoelectric switches 161 are arranged on components adjacent to the transmission component 132, corresponding to the rotation path of the transmission component 132. (Refer to...) Figures 2 to 4 The smart lock 100 also includes a mounting main board inside the lock housing. Four photoelectric switches 161 are mounted on one side of the mounting main board. The mounting main board has mounting holes for the lock cylinder sleeve of the lock cylinder assembly 120 to pass through. A knob sleeve 131 is connected to the end of the lock cylinder sleeve on the side opposite to the driven member. The four photoelectric switches 161 are arranged on the mounting main board at 90° intervals around the rotation path of the transmission member 132. When the transmission member 132 rotates, it causes the stop block 163 on it to rotate synchronously. When the stop block 163 rotates past a photoelectric switch 161, that photoelectric switch 161 can sense the stop block 163, thereby detecting the position of the transmission member 132.

[0062] It should be noted that the positions of the transmission component 132 and the knob sleeve 131 mentioned in the embodiments of the present invention can refer to their angular positions. For example, the four photoelectric switches 161 can be named first photoelectric switch 161, second photoelectric switch 161, third photoelectric switch 161, and fourth photoelectric switch 161 respectively in a clockwise direction. In a certain initial state, the stop 163 on the transmission component 132 is located at the first photoelectric switch 161. Then, after the transmission component 132 rotates 90° clockwise, the stop 163 rotates 90° to reach the second photoelectric switch 161. Therefore, the position of the transmission component 132 should be understood in conjunction with the magnitude and direction of the rotation angle. Similarly, the positions of other components that move by rotation can also be understood in this way.

[0063] Reference Figures 2 to 4 In some embodiments, the four photoelectric switches 161 can generate different detection information when they detect the passage of the block 163. Specifically, the first photoelectric switch 161 generates first block 163 information when it detects the passage of the block 163, the second photoelectric switch 161 generates second block 163 information when it detects the passage of the block 163, the third photoelectric switch 161 generates third block 163 information when it detects the passage of the block 163, and the fourth photoelectric switch 161 generates fourth block 163 information when it detects the passage of the block 163. When the transmission component 132 is in a certain initial state, the controller can determine that the stop 163 is located at the first photoelectric switch 161 based on the information detected by the first photoelectric switch 161. The transmission component 132 needs to rotate 90° clockwise. When the stop 163 is detected by the second photoelectric switch 161 and the second stop 163 information is transmitted to the controller, the controller can determine that the transmission component 132 has rotated to the correct position. (It should be noted that in this embodiment, the first photoelectric switch 161, the second photoelectric switch 161, the third photoelectric switch 161, and the fourth photoelectric switch 161 are distributed sequentially in a clockwise direction.) Subsequently, the controller can control the drive device 130 to stop the transmission component 132 from rotating or to continue rotating by a certain angle.

[0064] Reference Figure 3 According to some embodiments of the present invention, the first sensor 140 is configured to include a magnet 141 and a Hall switch 142 for sensing the magnet 141, wherein one of the magnet 141 and the Hall switch 142 is disposed on the knob sleeve 131 and the other is fixedly disposed on the outside of the knob sleeve 131.

[0065] In this way, the first sensor 140 can detect the position of the knob sleeve 131.

[0066] Specifically, when magnet 141 is located on knob sleeve 131, Hall switch 142 is located on a component adjacent to knob sleeve 131, corresponding to the rotation path of magnet 141 as knob sleeve 131 rotates; when Hall switch 142 is located on knob sleeve 131, magnet 141 is located on a component adjacent to knob sleeve 131, corresponding to the rotation path of Hall switch 142 as knob sleeve 131 rotates. For example, magnet 141 or Hall switch 142 can be located on the mounting motherboard. Exemplarily, in one embodiment, magnet 141 is located on knob sleeve 131. When knob sleeve 131 is in the first stop position, magnet 141 can be detected by Hall switch 142 and magnet 141 information is transmitted to the controller. When knob sleeve 131 rotates to the second stop position, magnet 141 moves away from Hall switch 142, making it undetectable by Hall switch 142. The controller can then determine whether knob sleeve 131 has rotated to the second stop position based on whether a stop signal is received.

[0067] According to some embodiments of the present invention, two magnets 141 are configured, and the two magnets 141 are symmetrically disposed on opposite sides of the knob sleeve 131.

[0068] In this way, the smart lock 100 can achieve the beneficial effect of eliminating the foolproof function when assembling lock body and other components.

[0069] Specifically, in this embodiment of the invention, the lock cylinder assembly 120 and the knob sleeve 131 can have a forward-mounted state and a reverse-mounted state. In the forward-mounted state, the lock cylinder assembly 120 and the knob sleeve 131 of the smart lock 100 are rotated 180° before installation, thus forming the reverse-mounted state of the smart lock 100. That is, the positions of the knob sleeve 131 are opposite in the forward-mounted and reverse-mounted states of the smart lock 100. For example, in the forward-mounted state, and when the smart lock 100 is in its first installation state, the first abutment position of the knob sleeve 131 is located at the left end of its rotation path, and the second abutment position is located at the upper end. In the reverse-mounted state, and when the smart lock 100 is in its first installation state, the first abutment position of the knob sleeve 131 is located at the right end of its rotation path, and the second abutment position is located at the lower end. Thus, since there are two symmetrically arranged magnets 141, the position of the knob sleeve 131 can be detected in both the forward-mounted and reverse-mounted states. Understandably, this allows for foolproof functionality, meaning that when assembling the smart lock 100, there is no need to specifically distinguish the installation orientation of the lock cylinder assembly 120 and the knob sleeve 131.

[0070] Reference Figure 2According to some embodiments of the present invention, the transmission member 132 is configured as a driven gear 132a, and the drive device 130 is configured as a motor 130a. The motor 130a is fixedly installed, and its output end extends toward the driven gear 132a to drive and connect to the driven gear 132a. It can be understood that configuring the transmission member 132 as a driven gear 132a and the drive device 130 as a motor 130a is a preferred embodiment. Of course, in other embodiments, both can be configured as other devices or components.

However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
