Description

Technical Field

[0001] The present application relates to the technical field of clutch devices, and in particular to a dual-mode clutch motor transmission structure. Background Art

[0002] In order to achieve more accurate and efficient power transmission, clutches, as an important component of mechanical equipment, are widely used in various equipment to achieve power transmission and disconnection during the transmission process. Reasonable design of clutches can not only improve the efficiency of mechanical systems, but also enhance the stability and reliability of equipment operation, thereby significantly improving user experience and extending the service life of equipment.

[0003] Invention patent announcement number CN117905810A discloses a new clutch and its intelligent control device, which are used in door drive systems. The new clutch includes a brush ring coaxial with the drive shaft, a micromotor platform, a sliding wheel, a driving wheel, and a driven wheel, including a micromotor and a brush mounted on the micromotor platform, and a propulsion chamber, a square nut and a cylindrical pin on the sliding wheel. The driving wheel is connected and fixed to the output shaft of the motor reducer through a shaft key. The output shaft of the micromotor is a screw rod, which rotates in the square nut, pushes the square nut forward or backward, drives the sliding wheel axially forward and backward, and then drives the cylindrical pin to move axially. The cylindrical pin passes through the driving wheel through hole, and then inserts or withdraws from the circular bar through hole on the driven wheel to achieve the clutch of the driving wheel and the driven wheel. However, clutch control through the cylindrical pin requires additional control components, and it is impossible to achieve automatic clutch at the beginning and end of rotation, so that the driven wheel cannot rotate freely when not driven, resulting in poor applicability of the clutch. Summary of the invention

[0004] In order to solve the problem that the clutch cannot automatically engage or disengage, resulting in poor applicability, the purpose of this application is to provide a dual-mode clutch motor transmission structure.

[0005] A dual-mode clutch motor transmission structure provided in this application adopts the following technical solution: A dual-mode clutch motor transmission structure includes: An output shaft, with a connecting piece fixed on the surface, and the output shaft can move along the axial direction relative to the housing; A clutch device, comprising a clutch sleeve, a clutch bracket, a clutch swing arm and a reset torsion spring, wherein the clutch sleeve and the clutch bracket are both sleeved on the outside of the output shaft and can rotate relative to the output shaft, the clutch sleeve and the connecting member form a detachable clamping connection, the clutch sleeve has a connecting block, the clutch swing arm and the reset torsion spring are both connected to the clutch bracket, the clutch swing arm can rotate relative to the clutch bracket and can abut against the connecting block, and the reset torsion spring is used to reset the clutch swing arm; A first gear is sleeved on the outer side of the output shaft, and a push block is provided on the edge of the first gear, which can push the clutch swing arm to rotate relative to the clutch bracket, so that the clutch swing arm abuts against the connecting block, so as to drive the output shaft to rotate; Wherein, after the output shaft moves, the engagement between the connecting member and the clutch sleeve can be released, and when the clutch swing arm is reset, the output shaft can rotate freely.

[0006] By adopting the above technical solution, the dual-mode clutch can release the engagement between the connecting member and the clutch sleeve by moving the output shaft relative to the housing along the axial direction, thereby realizing manual clutching. At the same time, the output shaft is automatically separated from the clutch device when it is not driven through the clutch device, so that the output shaft can rotate freely when it is not driven, which can be applied to more usage scenarios. When the first gear starts to rotate, the push block will push the clutch swing arm, so the clutch swing arm will abut the connecting block of the clutch sleeve after rotating relative to the clutch bracket, so that the first gear, the clutch swing arm and the clutch sleeve are connected together, and the clutch sleeve is engaged with the connecting member, so that the rotation can be transmitted to the output shaft, thereby completing the clutch connection. When the rotation is completed, the reset torsion spring resets the clutch swing arm, so that the clutch swing arm is separated from the connecting block, so that the output shaft is not controlled by the clutch device and can rotate freely, realizing automatic clutching. When the motor fails and cannot realize automatic clutching, the connecting member and the clutch sleeve can be separated by moving the output shaft, and the separated output shaft will also not be controlled by the clutch device and can rotate freely. Through automatic clutch and manual clutch, the clutch device is more convenient to operate and has better applicability. It also eliminates the hidden danger of life safety caused by the jamming of the door lock motor.

[0007] Optionally, a return spring is provided between the connecting member and the housing.

[0008] By adopting the above technical solution, the return spring can abut the connecting piece on the other side of the clutch sleeve, so that the connecting piece automatically forms a snap connection with the clutch sleeve when not subject to external force, thereby ensuring that the output shaft can remain under real-time control of the clutch device when not manually clutched, thereby improving the stability and reliability of the entire transmission structure.

[0009] Optionally, the clutch bracket includes an upper cover and a lower cover, and the clutch swing arm and the return torsion spring are installed between the upper cover and the lower cover.

[0010] By adopting the above technical solution, the clutch bracket includes an upper cover and a lower cover, and the clutch swing arm and the reset torsion spring are installed between the upper cover and the lower cover, so that the positions of the clutch swing arm and the reset torsion spring are more stable, thereby improving the overall reliability of the clutch device.

[0011] Optionally, the clutch swing arm includes a rotating part and two transmission arms, the rotating part is rotatably connected to the clutch bracket and can be pushed by the pushing block, the two transmission arms are both connected to the rotating part, and the transmission arms can abut the connecting block to transmit rotation to the clutch sleeve.

[0012] By adopting the above technical solution, transmission arms are connected to both sides of the rotating part, so that when the rotating part is pushed from two directions by the pushing block, the transmission arm on the opposite side can abut against the connecting block of the clutch sleeve, so that the rotation input in two directions can be automatically clutched through the clutch device, thereby improving the applicability of the transmission structure.

[0013] Optionally, two ends of the return torsion spring are respectively connected to two transmission arms, so that the transmission arms do not contact the connection block when no external force is applied.

[0014] By adopting the above technical solution, the reset torsion spring is connected to the two transmission arms respectively, so that the clutch swing arm is evenly acted upon by the force of the reset torsion spring, so that when there is no external force, it can maintain balance and will not be released from the connecting block, thereby achieving automatic clutch.

[0015] Optionally, magnetic beads are provided on the inner side of the shell, and the magnetic beads generate suction force on the clutch bracket to prevent the clutch bracket from rotating before the clutch swing arm abuts against the connecting block.

[0016] By adopting the above technical solution, since the reset torsion spring will generate rotational resistance to the pushing block pushing the clutch swing arm, if the force of the reset torsion spring is strong, the clutch swing arm will not be able to abut the connecting block, and only drive the clutch bracket to rotate. Therefore, by providing a magnetic bead, the rotation of the clutch bracket is also subject to resistance, so that the clutch swing arm will not rotate before abutting the clutch sleeve, thereby ensuring that the automatic clutch of the clutch device can proceed smoothly.

[0017] Optionally, it further includes a second gear, a third gear and an input shaft, wherein the input shaft is connected to the third gear, the third gear is connected to the second gear, and the second gear is connected to the first gear.

[0018] By adopting the above technical solution, the input shaft, the third gear and the second gear are added, so that the speed of the motor can be adjusted through multi-stage gear transmission, thereby achieving a wider range of speed regulation to meet the needs of different application scenarios.

[0019] Optionally, a threaded sleeve is connected to the input shaft, and the threaded sleeve is used to convert the rotation of the input shaft into the rotation of the third gear.

[0020] By adopting the above technical solution, the threaded sleeve on the input shaft can convert the rotation of the input shaft into the rotation of the third gear, thereby realizing effective conversion of the transmission mode.

[0021] Optionally, the number of the pushing blocks is two, and the number of the connecting blocks is three.

[0022] By adopting the above technical solution, since the first gear needs to idle for a distance before the pushing block pushes the clutch swing arm, by providing two pushing blocks, the idling distance of the first gear can be reduced and the transmission efficiency can be improved; the number of connecting blocks is set to three, which also enables the transmission arm to quickly abut the connecting blocks, and can also improve the connection efficiency.

[0023] Optionally, a first bearing is provided between the clutch bracket and the housing, and a second bearing is provided between the first gear and the housing.

[0024] By adopting the above technical solution, since the clutch bracket and the first gear rotate coaxially but have a rotation difference, they can be connected with different bearings to prevent them from affecting each other, thereby ensuring stable operation.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The dual-mode clutch can release the engagement between the connecting piece and the clutch sleeve by moving the output shaft relative to the housing along the axial direction, thereby realizing manual clutching. At the same time, the output shaft is automatically separated from the clutch device when it is not driven through the clutch device, so that the output shaft can rotate freely when it is not driven, which can be applied to more usage scenarios. When the first gear starts to rotate, the push block will push the clutch swing arm, so the clutch swing arm will abut the connecting block of the clutch sleeve after rotating relative to the clutch bracket, so that the first gear, the clutch swing arm and the clutch sleeve are connected together, and the clutch sleeve is engaged with the connecting piece, so that the rotation can be transmitted to the output shaft, thereby completing the clutch connection. When the rotation is completed, the reset torsion spring resets the clutch swing arm, so that the clutch swing arm is separated from the connecting block, so that the output shaft is not controlled by the clutch device and can rotate freely, realizing automatic clutching. When the motor fails and cannot realize automatic clutching, the connecting piece and the clutch sleeve can be separated by moving the output shaft, and the separated output shaft will also not be controlled by the clutch device and can rotate freely. Through automatic clutch and manual clutch, the clutch device is more convenient to operate and has better applicability; 2. Both sides of the rotating part are connected with transmission arms, so that when the rotating part is pushed from two directions by the pushing block, the transmission arm on the opposite side can abut against the connecting block of the clutch sleeve, so that the rotation input in two directions can be automatically clutched through the clutch device, thereby improving the applicability of the transmission structure; 3. Since the reset torsion spring will produce rotational resistance to the push block pushing the clutch swing arm, if the force of the reset torsion spring is strong, the clutch swing arm will not be able to abut the connecting block, and only drive the clutch bracket to rotate. Therefore, by providing a magnetic bead, the rotation of the clutch bracket is also subject to resistance, so that the clutch swing arm will not rotate before abutting the clutch sleeve, thereby ensuring that the automatic clutch of the clutch device can proceed smoothly.

DETAILED DESCRIPTION

[0028] The present application is further described in detail below in conjunction with the accompanying drawings.

[0029] A dual-mode clutch motor transmission structure, referring to Figure 1 , 2and 3, including a housing 1, an output shaft 2, a clutch device 3, a first gear 4, a second gear 5, a third gear 6 and an input shaft 7. The housing 1 is a mounting structure, the clutch device 3, the first gear 4, the second gear 5 and the third gear 6 are all mounted in the housing 1, and the output shaft 2 passes through the housing 1, and the input shaft 7 is connected to the inside of the housing 1 from the lower side of the housing 1. The housing 1 includes a top shell 11 and a bottom shell 12, the top shell 11 and the bottom shell 12 are connected to each other by a connecting hole 17, and the top shell 11 and the bottom shell 12 can be separated from each other, so that the components in the housing 1 can be more easily installed. A gear rod 16 is also provided on the inner side of the bottom shell 12 for fixing the second gear 5 and the third gear 6. The top shell 11 and the bottom shell 12 are both provided with an opening for the output shaft 2 to connect to the outside, and the edges of the opening are respectively provided with a first bearing 14 and a second bearing 15, wherein the first bearing 14 is used to fix the clutch device 3, and the second bearing 15 is used to fix the first gear 4.

[0030] Reference Figure 4 and 6 The output shaft 2 passes through the clutch device 3 and the first gear 4, and passes through the surface of the housing 1. The output shaft 2 can move in the housing 1 along the axial direction. After the output shaft 2 is moved, the output shaft 2 and the clutch device 3 can be separated, so that the rotation cannot be transmitted to the output shaft 2, thereby realizing manual clutch. A connecting member 21 is fixed on the surface of the output shaft 2. The clutch device 3 includes a clutch sleeve 31. The clutch sleeve 31 can be connected with the connecting member 21 and can be rotatably sleeved on the outside of the clutch sleeve 31. When the clutch sleeve 31 is connected with the connecting member 21, the clutch sleeve 31 and the output shaft 2 rotate synchronously, thereby transmitting the rotation of the clutch device 3 to the output shaft 2. A reset spring 22 is also provided between the connecting member 21 and the top shell 11. The reset spring 22 can maintain the connection between the connecting member 21 and the clutch sleeve 31 when there is no external force. And the return spring 22 will not affect the operation of manually moving the output shaft 2, so that the manual clutch can operate normally. When the clutch device 3 or other components fail and the output shaft 2 cannot be clutched, the output shaft 2 is pushed toward the axis direction of the output shaft 2 to separate the connecting piece 21 and the clutch sleeve 31, thereby separating the clutch device 3 and the output shaft 2, realizing manual clutch, and allowing the output shaft 2 to rotate freely normally.

[0031] Reference Figure 5 , 6and 7, the clutch device 3 also includes a clutch bracket 32, a clutch swing arm 33 and a reset torsion spring 34. The clutch bracket 32 ​​is sleeved on the outside of the output shaft 2 and can rotate relative to the output shaft 2. In addition, the clutch bracket 32 ​​can also rotate relative to the clutch sleeve 31. The clutch sleeve 31 has a connecting block 311, and the number of connecting blocks 311 is three and evenly distributed on the outside of the clutch sleeve 31. The clutch swing arm 33 and the reset torsion spring 34 are both installed on the clutch bracket 32, and the clutch bracket 32 ​​includes an upper cover 321 and a lower cover 322, wherein the upper cover 321 is connected to the first bearing 14, so that the clutch bracket 32 ​​can rotate relative to the housing 1, and the clutch swing arm 33 and the reset torsion spring 34 are installed between the upper cover 321 and the lower cover 322. The clutch swing arm 33 can rotate relative to the clutch bracket 32. The clutch swing arm 33 includes a rotating part 331 and two transmission arms 332. The rotating part 331 is connected to the upper cover 321 and the lower cover 322 through a rotating shaft, so that it can rotate relative to the clutch bracket 32. The rotating part 331 has a protruding part, which can form contact with the first gear 4, so that the rotation of the first gear 4 can drive the rotating part 331 to rotate. A transmission arm 332 is connected to each side of the rotating part 331. The transmission arm 332 will abut against the clutch sleeve 31 as the rotating part 331 is driven by the first gear 4. When the transmission arm 332 abuts against the clutch sleeve 31, the clutch swing arm 33 cannot rotate relative to the clutch bracket 32, and the first gear 4 can drive the clutch bracket 32 ​​and the clutch swing arm 33 to rotate. When the transmission arm 332 rotates along the surface of the clutch sleeve 31 and abuts against the connecting block 311, the transmission arm 332 can push the clutch sleeve 31 to rotate through the connecting block 311, and because the clutch sleeve 31 is engaged with the connecting member 21, the output shaft 2 is driven to rotate. Therefore, when the first gear 4 starts to rotate, the clutch device 3 can automatically complete the connection with the output shaft 2, thereby realizing automatic clutch to drive the output shaft 2 to rotate.

[0032] Reference Figure 5 , 67, the reset torsion spring 34 is also arranged between the upper cover 321 and the lower cover 322, and is used to restore the position of the clutch swing arm 33. The reset torsion spring 34 is installed on the connecting column connecting the upper cover 321 and the lower cover 322, and a transmission arm 332 is connected to each of the two ends. When the transmission arm 332 is in a balanced state without external force, the reset torsion spring 34 spreads the two transmission arms 332 apart and separates them from the connecting block 311. Therefore, when there is no external force, the clutch sleeve 31 is not connected to the clutch swing arm 33, so the transmission shaft can rotate freely. When the first gear 4 no longer rotates, the clutch swing arm 33 loses thrust. Under the action of the reset torsion spring 34, the transmission arm 332 is separated from the connecting block 311, so that the transmission shaft is not driven and controlled by the clutch device 3, and automatic clutch is realized. Through the clutch device 3, the transmission shaft can be driven by the clutch device 3 when driving, and will not be controlled by the connection when stopping driving, and can rotate freely, which can be applied to more usage scenarios and improve applicability.

[0033] Reference Figure 2 , 3 4, the first gear 4 is sleeved on the outside of the output shaft 2, and the edge of the first gear 4 exceeds the clutch bracket 32, and the exceeding part of the edge is provided with a push block 41. When the first gear 4 rotates until the push block 41 contacts the protruding part of the rotating part 331, the protruding block can push the rotating part 331 to rotate relative to the clutch bracket 32, thereby enabling the transmission arm 332 to abut against the connecting block 311 to drive the output shaft 2 to rotate. There are two push blocks 41, and by providing two push blocks 41, the first gear 4 can rotate a shorter distance before contacting the rotating part 331, thereby improving the transmission efficiency of the transmission structure.

[0034] Reference Figure 3 , a magnetic bead 13 is also provided inside the housing 1, and the magnetic bead 13 is provided corresponding to the clutch bracket 32, which can provide a certain resistance to the rotation of the clutch bracket 32. Since the clutch swing arm 33 is connected to the reset torsion spring 34, the equilibrium state of the reset torsion spring 34 is the position where the clutch swing arm 33 is not connected to the clutch sleeve 31. Therefore, when the push block 41 pushes the clutch swing arm 33, it will be subject to the resistance of the reset torsion spring 34, and the clutch bracket 32 ​​itself is in a state of being able to rotate, so it is easy to cause the clutch swing arm 33 to be unable to rotate and connect to the clutch sleeve 31. Instead, the resistance of the reset torsion spring 34 drives the clutch bracket 32 ​​to rotate, so the rotation cannot be transmitted to the clutch sleeve 31. Therefore, by providing a magnetic bead 13 to provide resistance to the rotation of the clutch bracket 32, the clutch swing arm 33 can be stably connected to the clutch sleeve 31 after being pushed, thereby ensuring the stable automatic clutching.

[0035] Reference Figure 2The rotation output end of the input shaft 7 is connected with a threaded sleeve 71, which contacts the third gear 6. The rotation is converted into vertical movement through the rotation of the threaded sleeve 71, thereby driving the rotation of the third gear 6. Since the diameter of the first gear 4 is relatively large, the rotation is amplified by the third gear 6 and the second gear 5, so that the rotation input of the input shaft 7 can be suitable for the use of the output shaft 2, thereby improving the practicality of the transmission structure.

[0036] The implementation principle of the embodiment of the present application is as follows: when the input shaft 7 starts to input rotation, the first gear 4 starts to rotate through the sequential driving of the third gear 6 and the second gear 5, and the first gear 4 idles until the push block 41 contacts the clutch swing arm 33. Under the push of the push block 41, the clutch swing arm 33 first rotates relative to the clutch bracket 32, so that the transmission arm 332 contacts the clutch sleeve 31. When the transmission arm 332 abuts the connecting block 311, the clutch swing arm 33 can no longer rotate relative to the clutch bracket 32, so that the first gear 4 can drive the clutch bracket 32 ​​to rotate. When the transmission arm 332 rotates to abut the connecting block 311, it drives the clutch sleeve 31 to rotate by pushing the connecting block 311, and then drives the output shaft 2 to rotate, so as to achieve automatic connection. When the input shaft 7 stops rotating, the first gear 4 also stops rotating, and loses the thrust of the push block 41. The clutch swing arm 33 leaves the surface of the clutch sleeve 31 under the action of the reset torsion spring 34, so as to achieve automatic separation, so that the output shaft 2 can rotate freely when not driven, and can be applied to different application scenarios. And eliminate the hidden danger of life safety caused by the door lock motor getting stuck.

[0037] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
