[0001] The invention relates to a clutch ring structure, a clutch mechanism and a positioning device, and in particular to a clutch ring structure, a transmission clutch mechanism and a transmission positioning device which can be used for transmission. Background Art

[0002] Doors are usually equipped with door locks. The well-known mechanical door locks include a keyhole and a latch. The door lock can be opened by inserting a key into the keyhole and rotating the latch. With the advancement of technology, electronic locks that use electricity have been developed. Through fingerprint, card sensing, face recognition or password input, the motor in the electronic lock can drive the transmission gear and transmission shaft to link the latch to open the electronic lock.

[0003] This type of electronic lock generally has a clutch structure on the transmission shaft to allow the transmission gear and the transmission shaft to jump when the latch reaches the position. In addition, since the door opening method can be divided into left-hand door opening and right-hand door opening, the previous electronic locks will have different mechanisms specifically for left-hand door opening and right-hand door opening. In order to facilitate users to purchase, electronic locks that can be used for left-hand door opening and right-hand door opening have been developed, and the electronic lock itself automatically determines which door opening method is applicable. As a result, the mechanisms of electronic locks are numerous and complicated, and there is still room for improvement.

[0004] Therefore, it is necessary to provide a clutch ring structure, a transmission clutch mechanism and a transmission positioning device to solve the above problems. Summary of the invention

[0081] Please refer to Figure 1 、 Figure 2 and Figure 3 wherein Figure 1 shows a perspective view of a transmission positioning device 1000 according to the first embodiment of the present invention, Figure 2 shows Figure 1 a partially exploded view of the transmission positioning device 1000 of the first embodiment, Figure 3 shows Figure 1 an exploded view of a transmission positioning module of the transmission positioning device 1000 of the first embodiment. The transmission positioning device 1000 includes a module housing 1100, a motor 1200, and a transmission clutch mechanism 1300.

[0082] The module housing 1100 includes an accommodation space SP1. The motor 1200 is disposed in the accommodation space SP1. The transmission clutch mechanism 1300 is disposed in the accommodation space SP1 and includes a clutch gear 1310, a transmission shaft 1320, and a clutch ring structure 1330. The clutch gear 1310 is driven by the motor 1200 and includes a tooth surface 1311 (labeled in Figure 5 ). The transmission shaft 1320 passes through the clutch gear 1310 and includes a shaft portion 1321 and a convex ring portion 1322. The convex ring portion 1322 protrudes radially from the shaft portion 1321 and includes an annular surface 1322a facing the tooth surface 1311. The clutch ring structure 1330 is sleeved outside the transmission shaft 1320 and clamped between the annular surface 1322a of the convex ring portion 1322 and the tooth surface 1311 of the clutch gear 1310. The clutch ring structure 1330 includes a ring body 1331, at least one clutch convex portion 1332, and at least one fixing member 1333. The ring body 1331 includes a first surface 1331a (labeled in Figure 5 ) and a second surface 1331b that are opposite to each other on an axis X1. At least one clutch convex portion 1332 protrudes outward from the first surface 1331a along the axis X1. At least one fixing member 1333 protrudes outward from the second surface 1331b along the axis X1.

[0083] Among them, at least one fixing member 1333 is fixed to one of the toroidal surface 1322a and the wheel surface 1311, at least one driving convex portion 1323 protrudes from the other of the toroidal surface 1322a and the wheel surface 1311 and faces at least one engaging convex portion 1332. When the motor 1200 applies a rotational force to drive the engaging gear 1310, the rotational force drives the transmission shaft 1320 to rotate through at least one driving convex portion 1323 and at least one engaging convex portion 1332. After the transmission shaft 1320 rotates from an initial position to a first positioning position, at least one engaging convex portion 1332 is pushed by at least one driving convex portion 1323 to drive the ring body 1331 to shift, and at least one engaging convex portion 1332 shifts from a first side of at least one driving convex portion 1323 to a second side. In other embodiments, the ring body 1331 may be slightly deformed when it shifts, but the present invention is not limited thereto.

[0084] Thus, by the engaging ring structure 1330 including the engaging convex portions 1332 and the fixing members 1333 protruding from the ring body 1331 in different directions, it is convenient to arrange the engaging ring structure 1330 on other components. Therefore, the fixing member 1333 can be selected to be fixed to the transmission shaft 1320 or the engaging gear 1310 when the transmission engaging mechanism 1300 is arranged, and it has flexibility in structural design and arrangement. The details of the transmission positioning device 1000 will be described in detail later.

[0085] Please refer to Figure 4 , and also refer to Figure 2 and Figure 3 wherein Figure 4 illustrates Figure 3Schematic diagram of the interior of the drive positioning module of the first embodiment and the battery assembly 1900. The module housing 1100 can generally be in the shape of a rectangular frame and includes a first housing 1110 and a second housing 1120. The second housing 1120 is combined with the first housing 1110 to form an accommodation space SP1. The second housing 1120 can include a flexible clamping portion 1121 that protrudes toward the first housing 1110 along the axis X1, and the flexible clamping portion 1121 is used to clamp and limit the motor 1200. Specifically, the first housing 1110 and the second housing 1120 can be assembled by snap-fastening. The cover plate of the first housing 1110 can include a shaft hole 1111 through which one end of the shaft portion 1321 can pass through. The side wall included in the second housing 1120 has a longer length on the axis X1 and mainly provides the accommodation space SP1 for placing various components. The flexible clamping portion 1121 protrudes integrally from the back plate of the second housing 1120. The number of the flexible clamping portions 1121 can be two, and the two flexible clamping portions 1121 are located at one end of the motor 1200. Each flexible clamping portion 1121 can have a pushing block to push the motor 1200 toward the side wall of the second housing 1120. The flexible clamping portion 1121 has elasticity to reset after slight deformation. In this way, the motor 1200 can be fixed without using screws and has the function of clamping and limiting the motor 1200, and the elastic vibration absorption can be achieved through the flexible clamping portion 1121, and the effect of reducing vibration and abnormal noise can be achieved without using foam. The back plate of the second housing 1120 can also include a transmission shaft through hole 1123 through which the other end of the shaft portion 1321 can pass through.

[0086] The drive positioning device 1000 can also include a battery assembly 1900. The accommodation space SP1 is divided into a battery area SP12 and a drive area SP11. The module housing 1100 can also include an insertion port 1130 communicating with the battery area SP12, and the battery assembly 1900 is inserted into the battery area SP12 through the insertion port 1130. As Figure 2 and Figure 3 shown, the second housing 1120 can also include a partition wall 1122 to divide the accommodation space SP1 into a battery area SP12 and a drive area SP11, and the second housing 1120 does not have the upper side wall, and an insertion port 1130 can be formed for the battery assembly 1900 to be inserted. The battery assembly 1900 can include a battery support base and a battery. After the battery assembly 1900 is inserted into the battery area SP12, the plate member of the battery support base can close the insertion port 1130. The drive area SP11 can be used for placing the motor 1200 and the drive clutch mechanism 1300. The flexible clamping portion 1121 protrudes from the back plate of the second housing 1120 at the position corresponding to the drive area SP11, and a plurality of component fixing portions can also protrude or be formed on the back plate of the second housing 1120, but not limited thereto.

[0087] The transmission and positioning device 1000 may further include a power transmission mechanism 1600. The power transmission mechanism 1600 may further include a worm 1610, a worm wheel 1620, and a transmission gear 1630. The worm 1610 is sleeved on the output shaft of the motor 1200. The worm wheel 1620 meshes with the worm 1610 and is driven by the worm 1610. The transmission gear 1630 meshes with the worm wheel 1620 and is driven by the worm wheel 1620. The clutch gear 1310 may mesh with the transmission gear 1630. Thus, the motor 1200 can drive the clutch gear 1310 to rotate through the power transmission mechanism 1600.

[0088] Please refer to Figure 5 and also refer to Figures 2 to 4 where Figure 5 shows Figure 3 an exploded view of the transmission and clutch mechanism 1300 of the transmission and positioning module of the first embodiment. Please note that Figure 5 the perspective of Figures 1 to 4 is opposite to the perspective of

[0089] Specifically, the clutch ring structure 1330 is fixed to the clutch gear 1310. The number of the clutch convex portions 1332 may be two, and the number of the fixing members 1333 may be two. The ring body 1331 includes two arc segments. Each fixing member 1333 includes two connecting arms 1333a and a limiting portion 1333b. The two connecting arms 1333a of each fixing member 1333 are connected between the two arc segments. The limiting portion 1333b of each fixing member 1333 is connected between the two connecting arms 1333a of each fixing member 1333, and an angle θ is formed between each connecting arm 1333a and the second surface 1331b.

[0090] The clutch gear 1310 may further include two grooves 1312 located on the wheel surface 1311, and the two grooves 1312 respectively correspond to the two limiting portions 1333b for fixing the limiting portions 1333b.

[0091] The number of the transmission convex portions 1323 may be two and they are arranged at intervals on the annular surface 1322a, and each transmission convex portion 1323 may include a abutting plane 1323b (marked in Figure 7 ) and two slope surfaces 1323a (marked in Figure 7 ). The two slope surfaces 1323a of each transmission convex portion 1323 are respectively connected to both sides of the abutting plane 1323b, so that a cross-section of the transmission convex portion 1323 is generally trapezoidal. Furthermore, the shaft portion 1321 of the transmission shaft 1320 is divided into a front shaft section and a rear shaft section by the convex ring portion 1322. The front shaft section is used to sequentially pass through the clutch ring structure 1330 and the gear hole of the clutch gear 1310, so that the clutch ring structure 1330 can be clamped between the convex ring portion 1322 and the clutch gear 1310, and the clutch convex portion 1332 can correspond to the transmission convex portion 1323.

[0092] Please refer to Figure 6 and Figure 7 , and also refer to Figures 2 to 5 , wherein Figure 6 shows Figure 5 a front view operation schematic diagram of the transmission clutch mechanism 1300 of the first embodiment, Figure 7 shows Figure 5 a side view operation schematic diagram of the transmission clutch mechanism 1300 of the first embodiment. Please note that Figure 6 the front view in Figure 5The result obtained by looking from left to right in the figure. The rear shaft section of the shaft portion 1321 can be used to connect a latch. By rotating the shaft portion 1321 forward or backward, the latch can extend or retract. Therefore, when the motor 1200 rotates, a rotational force can be applied to the clutch gear 1310, and the rotational force can drive the transmission shaft 1320 to rotate through the transmission convex portion 1323 and the clutch convex portion 1332. Specifically, initially, the clutch convex portion 1332 can be located on the first side of the transmission convex portion 1323. As the clutch gear 1310 rotates, the clutch convex portion 1332 pushes the transmission convex portion 1323 to rotate the transmission shaft 1320, enabling the latch to reach a certain position. At this time, the transmission shaft 1320 can no longer rotate, but the clutch gear 1310 continues to rotate. At this time, since the limiting portion 1333b is fixed, the clutch convex portion 1332 is pushed and the linkage ring body 1331 deflects, and the connecting arm 1333a may be deformed or deflected due to linkage. Therefore, the clutch convex portion 1332 can move from the first side of the transmission convex portion 1323 to the second side. In addition to preventing damage to the motor 1200, it can also drive the transmission shaft 1320 to reset during reverse rotation. Please note that assuming that the latch is in the extended and locked state at this time, when the user inserts a key into the keyhole to drive the transmission shaft 1320 to open the door in the reverse direction, since the clutch convex portion 1332 has moved to the second side of the transmission convex portion 1323, it will not block the door opening. In addition, Figure 5 and Figure 6 The figure shows an example of opening the door in a first direction (for example, left-opening), but it is not limited thereto.

[0093] Please refer to Figure 8 and Figure 9 and also refer to Figures 2 to 7 wherein Figure 8 shows Figure 3 A schematic diagram of a circuit board 1400 and a signal washer 1500 of the transmission positioning module of the first embodiment. Figure 9 shows Figure 3 Another schematic diagram of the circuit board 1400 and the signal washer 1500 of the transmission positioning module of the first embodiment. The transmission positioning device 1000 may further include a circuit board 1400 and a signal washer 1500. The circuit board 1400 can be disposed on the side of the clutch gear 1310 away from the clutch ring structure 1330 and includes a through hole 1440, a first metal contact portion 1410, and a second metal contact portion 1420. The through hole 1440 is for the transmission shaft 1320 to pass through, and the first metal contact portion 1410 and the second metal contact portion 1420 are arranged around the through hole 1440. The signal washer 1500 can be sleeved on the transmission shaft 1320 and is located between the circuit board 1400 and the clutch gear 1310. The signal washer 1500 includes a signal spring arm 1510. When the transmission shaft 1320 is in the first positioning position, the signal spring arm 1510 contacts the first metal contact portion 1410. When the transmission shaft 1320 is in a second positioning position, the signal spring arm 1510 contacts the second metal contact portion 1420.

[0094] Specifically, as Figure 3 and Figure 4 shown, the circuit board 1400 is adjacent to the first housing 1110, and the through hole 1440 corresponds to the shaft hole 1111. As Figure 8 and Figure 9 shown, the circuit board 1400 further includes a third metal contact portion 1430. The third metal contact portion 1430, the first metal contact portion 1410, and the second metal contact portion 1420 are arranged around the through hole 1440, and the third metal contact portion 1430 is 90 degrees different from the first metal contact portion 1410 and the second metal contact portion 1420 respectively. Each of the first metal contact portion 1410, the second metal contact portion 1420, and the third metal contact portion 1430 may include two bare copper areas, which are formed by exposing the copper part of the circuit board 1400 to form bare copper areas, providing convenience in the manufacturing process, but not limited thereto.

[0095] The signal washer 1500 may include a collar 1520, which is used to sleeved on the shaft portion 1321 of the transmission shaft 1320 and integrally connected to the signal spring arm 1510. The signal spring arm 1510 includes two arm portions 1511 and a connecting portion 1512. One end of the connecting portion 1512 is connected to the collar 1520, and the two arm portions 1511 are perpendicularly connected to the other end of the connecting portion 1512. Thereby, when the transmission shaft 1320 rotates, the signal spring arm 1510 can contact the first metal contact portion 1410, the second metal contact portion 1420, or the third metal contact portion 1430, so as to transmit different signals to a controller on the circuit board 1400 to confirm whether the transmission shaft 1320 is located at the first positioning position, the second positioning position, or the initial position. It should be noted that when the number of bare copper areas is two and the number of arm portions 1511 is two, it can be further ensured that the arm portions 1511 can correspond to the first metal contact portion 1410, the second metal contact portion 1420, or the third metal contact portion 1430 after rotation, so as to avoid poor sensing. In addition, in other embodiments, the two arm portions do not necessarily need to be perpendicularly connected to the connecting portion, as long as they extend three-dimensionally from the connecting portion towards the circuit board, that is, the arm portions and the connecting portion are not coplanar, and the arm portions can swing up and down.

[0096] Accordingly, by providing the first metal contact portion 1410, the second metal contact portion 1420, the third metal contact portion 1430, and the signal washer 1500 on the circuit board 1400, it is not necessary to provide a known micro switch, nor to provide a convex block to trigger the micro switch like a known clutch ring structure, thus simplifying the clutch ring structure, and the signal washer 1500 can also have the function of a general washer.

[0097] During assembly, the components can be positioned within the second housing 1120 first, and then the first housing 1110 can be assembled. The transmission positioning device 1000 may further include a decorative cover 1810 and a knob 1820. The decorative cover 1810 is disposed on the module housing 1100, particularly covering the module housing 1100 in the direction from the first housing 1110 towards the second housing 1120. The knob 1820 is connected to the transmission shaft 1320 and includes an operating portion exposed outside the decorative cover 1810. The decorative cover 1810 may include an upper cover 1811 and a lower cover 1812 that are assembled with each other. The lower cover 1812 may include holes, and the knob 1820 is disposed on the lower cover 1812 and corresponds to the holes. In this way, after the transmission shaft 1320 extends out from the shaft hole 1111 of the first housing 1110, it can be inserted into the knob 1820 through the holes and can be driven to rotate by the knob 1820. The transmission positioning device 1000 may further include a mounting plate 1700 disposed on the back plate of the second housing 1120, and can mount the transmission positioning device 1000 at a predetermined position, such as on a door.

[0098] Please refer to Figure 10A and Figure 10B and also refer to Figures 2 to 9 wherein Figure 10A shows Figure 1 a partial step flow chart of the transmission positioning device 1000 of the first embodiment for determining the door opening direction, Figure 10B shows Figure 1 another partial step flow chart of the transmission positioning device 1000 of the first embodiment for determining the door opening direction. By connecting the latch to the transmission shaft 1320, the transmission positioning device 1000 can be used as an electronic lock. Since the latch is arranged on different sides of the transmission positioning device 1000 according to different door opening directions. For example, if looking at the door from the outside towards the inside, a left-opening door means the door rotates from the right side to the left side. Therefore, the latch can be located on Figure 6 the right side (equivalent to Figure 8 the left side of Figure 6 ), and can extend towards the Figure 6 right side of Figure 8 and retract towards the Figure 6 left side of Figure 6 (equivalent to Figure 6 the right side of

[0099] When executing the automatic opening direction determination method, the controller can be disposed on the circuit board 1400 and is used to issue a first direction opening determination instruction to start the motor 1200 to drive the clutch gear 1310 to rotate in the first rotation direction. If the controller receives a first signal within a determination time, it determines that the first direction is the opening direction and powers off the motor 1200; if the controller does not receive the first signal within the determination time, the controller issues a second direction opening determination instruction to start the motor 1200 to drive the clutch gear 1310 to rotate in a second rotation direction. If the controller receives a second signal within the determination time, it determines that the second direction is the opening direction and powers off the motor 1200. Wherein, the first signal is generated when the signal arm 1510 contacts the first metal contact portion 1410, the second signal is generated when the signal arm 1510 contacts the second metal contact portion 1420, and the signal arm 1510 can contact the third metal contact portion 1430 when the transmission shaft 1320 is in the initial position.

[0100] If the controller does not receive the first signal within the determination time, the controller can first reverse the motor 1200 in the second rotation direction, and then the controller issues a second direction opening determination instruction. In addition, the controller can start counting a clutch time after receiving the first signal or the second signal, and then turn off the motor 1200. In the first embodiment, the time for the motor 1200 to drive the signal washer 1500 to rotate 90 degrees is known. When making a determination, since the transmission shaft 1320 may not be in the initial position, the time for the transmission shaft 1320 to rotate to the first positioning position or the second positioning position may exceed the time for the signal washer 1500 to rotate 90 degrees. Therefore, the insurance uses the time for the signal washer 1500 to rotate 180 degrees as the determination time. In addition, after the transmission shaft 1320 reaches the positioning, if the motor 1200 is immediately turned off, the clutch protrusion 1332 has not yet moved from the first side of the transmission protrusion 1323 to the second side or from the second side to the first side. This will cause the transmission shaft 1320 not to be reset after the motor 1200 reverses, and will also affect the user's manual opening. Therefore, the motor 1200 needs to be delayed in turning off, and this delayed clutch time for turning off is the time for the clutch ring structure 1330 to clutch once.

[0101] Specifically, such as Figure 10AAs shown, in step S01, the motor 1200 is in a stationary state, that is, the motor 1200 is not powered on and not rotating. Then, step S02 is executed. When the left / right door opening state is not memorized and the password is successfully input, the controller can issue a first-direction door opening determination instruction, that is, step S03 can be executed to enter the "first-direction door opening" determination, power on the motor 1200, and enter step S04. After the motor 1200 is powered on, it rotates in the first rotation direction, and then enters step S05 to confirm whether a first signal is received within the determination time. If it is "first-direction door opening", the motor 1200 can successfully drive the transmission shaft 1320 to drive the signal washer 1500, so that the signal arm 1510 can contact the first metal contact part 1410 to generate a first signal. On the contrary, if the first signal is not generated, it means that it may not be "first-direction door opening", so the signal arm 1510 cannot contact the first metal contact part 1410 to generate a first signal. Therefore, when the first signal is successfully received in step S05 within the determination time, the motor 1200 is turned off and stopped after a delay time in step S06, and then enters step S07. The controller memorizes that the "first-direction door opening" is successful, and the door opening direction determination ends. In other words, receiving the first signal means that the latch can successfully extend in the Figure 8 left side direction to lock the door. Therefore, after unlocking, the door can be pushed open in the "first-direction door opening" manner.

[0102] When the first signal is not successfully received in step S05 within the determination time, it enters step S08. The controller reverses the motor 1200 and memorizes 1 error of "first-direction door opening", and then enters step S09. The motor 1200 is powered off and stationary. At this time, it can be paused for 0.5 seconds to 1 second first, and then powered on again. Next, the controller can issue a second-direction door opening determination instruction, that is, execute step S10 to enter the "second-direction door opening" determination. The motor 1200 is powered on. At this time, it enters step S11. After the motor 1200 is powered on, it rotates in the second rotation direction, and then enters step S12 to confirm whether a second signal is received within the determination time. If it is "second-direction door opening", the motor 1200 can successfully drive the transmission shaft 1320 to drive the signal washer 1500, so that the signal arm 1510 can contact the second metal contact part 1420 to generate a second signal. On the contrary, if the second signal is not generated, it means that it may not be "second-direction door opening", so the signal arm 1510 cannot contact the second metal contact part 1420 to generate a second signal. Therefore, when the second signal is successfully received in step S12 within the determination time, the motor 1200 is turned off and stopped after a delay time in step S13, and then enters step S14. The controller memorizes that the "second-direction door opening" is successful, and the door opening direction determination ends. Please note especially that receiving the second signal means that the latch can successfully extend in the Figure 8 right side direction to lock the door. Therefore, after unlocking, the door can be pushed open in the "second-direction door opening" manner.

[0103] As Figure 10A and Figure 10B shown, when the second signal is not successfully received within the determination time in step S12, step S15 is entered, the controller reverses the motor 1200, and "door opening in the second direction" is memorized as an error once, and then step S16 is entered, and the motor 1200 is powered off and stationary. Please note that reversing the motor 1200 in steps S08 and S15 means the direction opposite to the original rotation direction, rather than a specific rotation direction.

[0104] After that, steps S17, S18, and S19 can be entered again. This part is the same as steps S03, S04, and S05, and it is further determined whether to enter steps S20, S21 or enter step S22 according to the judgment result of step S19. Steps S20 and S21 are the same as steps S06 and S07. In step S22, the controller reverses the motor 1200, and "door opening in the first direction" is memorized as an error twice, and then step S23 is entered, and the motor 1200 is powered off and stationary. Then, steps S24, S25, and S26 are entered. This part is the same as steps S10, S11, and S12, and it is further determined whether to enter steps S27, S28 or enter steps S29, S30 according to the judgment result of step S26. Steps S27 and S28 are the same as steps S13 and S14. In step S29, the motor 1200 is turned off and stopped after a delay time, and finally step S30 is entered, and the controller memorizes the failure, and the determination of the door opening direction ends. That is to say, if the determinations of "door opening in the first direction" and "door opening in the second direction" have both failed twice, there may be a problem with the transmission positioning device 1000 itself, and further confirmation is required.

[0105] Please refer to Figure 11 , in which Figure 11 shows an exploded schematic view of a transmission clutch mechanism 2300 according to the second embodiment of the present invention. The transmission clutch mechanism 2300 is similar to the transmission clutch mechanism 1300 of the first embodiment, but the clutch ring structure 2330 is fixed to the transmission shaft 2320. Specifically, the clutch gear 2310 may further include a limiting wall 2313 protruding from the wheel surface and forming a chamber with an intermediate area of the wheel surface. The chamber can accommodate the ring body 2331. Two transmission protrusions 2314 are spaced apart in the intermediate area of the wheel surface, and each transmission protrusion 2314 is connected to the inner edge of the limiting wall 2313 and is used to cooperate with the clutch protrusion 2332. The transmission shaft 2320 may include two positioning grooves 2324 spaced apart on the ring surface 2322a. Each fixing member 2333 can be fixed to each positioning groove 2324, and can be fixed, for example, by heat melting or riveting. In this way, when the clutch gear 2310 rotates, the clutch ring structure 2330 can be driven to drive the transmission shaft 2320 to rotate through the transmission protrusions 2314.

[0106] Please refer to Figure 12 , in which Figure 12A disassembled schematic view of a transmission clutch mechanism 3300 according to a third embodiment of the present invention is shown.

The positioning ring 3333c can be sleeved on the shaft portion 3321 of the transmission shaft 3320, so that it can also move together with the transmission shaft 3320.
