[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0052] like Figures 1 to 5As shown, according to a first aspect of this application, a clutch mechanism is provided. The clutch mechanism includes a first driving member 1, a transmission member 2, a connecting member 3, and a second driving member 4. The transmission member 2 is driveably connected to the first driving member 1. The transmission member 2 is configured to drively connect to a rotating shaft 7. The transmission member 2 has a first position driveably connected to the rotating shaft 7 and a second position driveably separated from the rotating shaft 7. The connecting member 3 is connected to the transmission member 2. The connecting member 3 has an extension 31 bent away from the axis of the transmission member 2. The second driving member 4 is connected to the extension 31. The second driving member 4 is configured to drive the transmission member 2 to switch from the first position to the second position.

[0053] In this embodiment, by connecting the first driving member 1 to the transmission member 2, the first driving member 1 can drive the rotating shaft 7 to rotate via the transmission member 2. The second driving member 4 can drive the transmission member 2 to move via the connecting member 3, so that the transmission member 2 can switch from a first position to a second position, thereby separating the transmission of the transmission member 2 from the rotating shaft 7 and realizing the clutch function. Since the connecting member 3 has an extension 31 bent away from the axis of the transmission member 2, and the second driving member 4 is connected to the extension 31, the second driving member 4 does not need to be coaxially arranged with the transmission member 2, reducing the machining accuracy requirements of the clutch mechanism.

[0054] Understandably, the clutch mechanism can switch the connection state between the transmission component 2 and the rotating shaft 7. Specifically, when the transmission component 2 is in the first position, the transmission component 2 and the rotating shaft 7 are connected. At this time, the first drive component 1 can drive the rotating shaft 7 to rotate through the transmission component 2. When the transmission component 2 is in the second position, the transmission component 2 and the rotating shaft 7 are disengaged. At this time, the drive shaft 11 of the first drive component 1 and the transmission component 2 rotate freely, and the rotating shaft 7 cannot be driven to rotate by the first drive component 1.

[0055] It should be noted that the first driving component 1 is an electric drive mechanism. When the transmission component 2 is in the first position, so that the transmission component 2 is connected to the rotating shaft 7, the rotating shaft 7 is driven to rotate by the first driving component 1, and the rotating shaft 7 is in electric drive mode. When the transmission component 2 is in the second position, so that the transmission component 2 is disengaged from the rotating shaft 7, the rotating shaft 7 can rotate under the action of external force, and the rotating shaft 7 is in manual drive mode. The control switch for the first driving component 1 can be located on the roller shutter guide rail.

[0056] like Figure 3 As shown, the connector 3 can be L-shaped, forming an extension 31 that bends away from the axis of the transmission member 2. The connector 3 is connected to the outer surface of the transmission member 2. The extension 31 is connected to the second drive member 4 by fasteners. When the second drive member 4 is activated, the transmission member 2 can be driven to move through the extension 31 and the connector 3, so that the transmission member 2 can switch from the first position to the second position.

[0057] like Figure 3As shown, in some embodiments, the first driving member 1 has a driving shaft 11. An abutment portion 12 is formed on the circumferential surface of the driving shaft 11. An elastic member 13 is sleeved on the driving shaft 11. The opposite ends of the elastic member 13 abut against the abutment portion 12 and the transmission member 2, respectively. The elastic member 13 is configured to drive the transmission member 2 to switch from a second position to a first position.

[0058] It is understood that the elastic element 13 abuts against the abutment portion 12 and the transmission element 2. When the transmission element 2 is in the first position, the elastic element 13 is in a natural or contracted state. When the transmission element 2 switches from the first position to the second position, the elastic element 13 is compressed and stores elastic potential energy. After the second driving element 4 removes its force on the connecting element 3, the elastic element 13 can release its elastic potential energy, thereby driving the transmission element 2 to switch from the second position to the first position. Thus, the self-resetting of the transmission element 2 can be achieved through the elastic element 13.

[0059] It should be noted that the abutment portion 12 can be configured as an annular shape, with the abutment portion 12 surrounding the circumferential surface of the drive shaft 11. The abutment portion 12 can be integrally formed with the drive shaft 11.

[0060] The transmission component 2 is slidably connected to the drive shaft 11, allowing it to slide towards or away from the drive shaft 11. When the transmission component 2 slides towards the drive shaft 11, it switches from a first position to a second position, thus disengaging the transmission component 2 from the rotating shaft 7. When the transmission component 2 slides away from the drive shaft 11, it switches from a second position to a first position, thus reconnecting the transmission component 2 to the rotating shaft 7. It should be noted that while the transmission component 2 switches between the first and second positions, it remains connected to the drive shaft 11, and the connection between the transmission component 2 and the drive shaft 11 is secured by a spline to prevent relative rotation between them, ensuring that the drive shaft 11 can drive the transmission component 2 to rotate.

[0061] When the transmission member 2 is in the first position, the transmission member 2 and the abutment portion 12 are spaced apart. The distance between the transmission member 2 and the abutment portion 12 is the maximum stroke of the transmission member 2. When the transmission member 2 moves close to or comes into contact with the abutment portion 12, the transmission member 2 is in the second position.

[0062] In some embodiments, the elastic element 13 is a spring.

[0063] like Figure 3 and Figure 4 As shown, in some embodiments, the second driving member 4 is configured to drive the transmission member 2 to switch from a first position to a second position under the action of an external force. The elastic member 13 is configured to drive the transmission member 2 to switch from the second position to the first position when the external force acting on the second driving member 4 disappears.

[0064] Understandably, the second driving component 4 is a manually operated component. When an external force is applied to the second driving component 4, it can drive the transmission component 2 to switch from the first position to the second position. During this process, the elastic element 13 is compressed and stores elastic potential energy. When the external force acting on the second driving component 4 disappears, the elastic element 13 releases its elastic potential energy, thereby driving the transmission component 2 to switch from the second position to the first position. Thus, the self-resetting of the transmission component 2 can be achieved through the elastic element 13.

[0065] like Figure 4 As shown, in some embodiments, the transmission member 2 has a receiving cavity 21. The drive shaft 11 passes through the receiving cavity 21 and is drively connected to the transmission member 2. The elastic member 13 has a first section located within the receiving cavity 21 and a second section extending out of the receiving cavity 21. The first section abuts against the transmission member 2. The second section abuts against the abutting portion 12.

[0066] Understandably, the receiving cavity 21 formed by the transmission member 2 can be used to accommodate the drive shaft 11 and the first section of the receiving elastic member 13. This reduces the axial dimension of the clutch mechanism. The length of the second section of the elastic member 13 defines the maximum stroke of the transmission member 2. When the elastic member 13 is fully compressed into the receiving cavity 21, the transmission member 2 will abut against the drive shaft 11, at which point the transmission member 2 will be unable to move in the direction of the first drive member 1.

[0067] It should be noted that the transmission component 2 also forms a connecting cavity that communicates with the receiving cavity 21. The end of the drive shaft 11 passes through the receiving cavity 21 and is disposed within the connecting cavity. A spline is formed on the outer surface of the end of the drive shaft 11, and a spline is also formed on the wall surface of the connecting cavity. The spline at the end of the drive shaft 11 engages with the spline on the wall surface of the connecting cavity to achieve circumferential anti-rotation between the drive shaft 11 and the transmission component 2, and to allow the drive shaft 11 and the transmission component 2 to move relative to each other in the axial direction.

[0068] In some embodiments, the first drive element 1 includes a motor having a worm gear transmission structure.

[0069] Understandably, since the first driving component 1 is a motor with a worm gear transmission structure, it possesses a self-locking force. Therefore, the first driving component 1 can also lock the positions of the transmission component 2 and the rotating shaft 7, preventing them from being forcibly rotated under external force. When this clutch mechanism is applied to the roller shutter device of a pickup truck, it can prevent the roller shutter from being forcibly opened by external force when it is closed, thus improving anti-theft capabilities.

[0070] It should be noted that the motor with the worm gear drive structure can use single-stage reduction, double-stage reduction, or multi-stage reduction.

[0071] Please continue reading. Figure 3 and Figure 4 In some embodiments, the clutch mechanism further includes a first housing 5. The transmission component 2, the connecting component 3, and the second driving component 4 are all disposed within the first housing 5. The first driving component 1 is located outside the first housing 5.

[0072] It is understandable that by housing the transmission component 2, the connecting component 3, and the second driving component 4 within the first housing 5, a protective effect can be achieved for these components. The first driving component 1 is located outside the first housing 5 to facilitate its maintenance.

[0073] Please continue reading. Figure 3 and Figure 4 In some embodiments, the first housing 5 has a slot 51. The extension 31 has a mounting hole. The second drive member 4 includes a positioning pin 41 and a pull rope 42. The positioning pin 41 passes through the mounting hole and is fixedly connected to the extension 31. The pull rope 42 is connected to the positioning pin 41, and the free end of the pull rope 42 extends out of the first housing 5 and is connected to a pull ring 43. The positioning pin 41 has a protruding section 411 that passes through the mounting hole. The protruding section 411 is inserted into the slot 51.

[0074] Understandably, by applying an external force to the pull ring 43, the pull ring 43 drives the pull rope 42, which in turn drives the positioning pin 41 to move away from the slot 51. Based on the movement of the positioning pin 41, the extension 31 can be driven to move. The movement of the extension 31 can then switch the transmission member 2 from the first position to the second position. Thus, the transmission member 2 can be switched from the first position to the second position under the drive of an external force.

[0075] It should be noted that, due to the travel limitation of the transmission component 2, when the transmission component 2 is in the second position, the protruding section 411 of the positioning pin 41 is not completely disengaged from the slot 51. This ensures that the positioning pin 41 remains within the slot 51, preventing it from falling out and failing to reset. When the external force is removed, the elastic element 13 drives the transmission component 2 to self-reset, allowing the protruding section 411 of the positioning pin 41 to fully re-insert into the slot 51.

[0076] In some embodiments, the protruding section 411 of the positioning pin 41 may be configured as tapered so that the protruding section 411 passes through the slot 51.

[0077] In some embodiments, the positioning pin 41 is arranged parallel to the transmission member 2 so that the positioning pin 41 and the transmission member 2 can move synchronously in the axial direction.

[0078] In some embodiments, a connector is constructed within the first housing 5, and a slot 51 is formed on the connector. The groove depth direction of the slot 51 is parallel to the axial direction of the transmission member 2.

[0079] In some embodiments, the pull cord 42 may be made of nylon. A rubber sleeve is fitted onto the pull ring 43.

[0080] In some embodiments, the second driving member 4 may also be an electric drive mechanism. In this case, after the second driving member 4 drives the transmission member 2 to switch from the first position to the second position, the transmission member 2 can be kept in the second position. Furthermore, the electric drive member 4 can also enable remote operation, improving operational convenience. For example, the second driving member 4 is an electric telescopic rod. The electric telescopic rod is disposed within the first housing 5, and its telescopic end is connected to the extension portion 31. Based on the extension of the telescopic end, the transmission member 2 is driven to switch from the first position to the second position.

[0081] like Figure 3 and Figure 4 As shown, in some embodiments, the first housing 5 has a first mounting hole 52 formed in its wall. A protective sleeve 53 is provided inside the first mounting hole 52. The free end of the pull rope 42 passes through the protective sleeve 53 and exits the first housing 5, and is connected to the pull ring 43.

[0082] Understandably, the first mounting hole 52 is used to thread the pull rope 42 through, allowing it to pass through the first housing 5 and connect to the pull ring 43 located outside the first housing 5. The protective sleeve 53 serves two purposes: firstly, it protects against stretching, preventing the pull rope 42 from contacting the housing wall of the first housing 5 and causing wear; secondly, the protective sleeve 53 restricts the direction of movement of the pull rope 42, preventing it from moving erratically and interfering with the movement of the components.

[0083] In some embodiments, the clutch mechanism further includes a connector 6. The connector 6 is drive-connected to the rotating shaft 7. Specifically, when the transmission member 2 is in the first position, the transmission member 2 is drive-connected to the connector 6. When the transmission member 2 is in the second position, the transmission member 2 is drive-disconnected from the connector 6.

[0084] It is understandable that connector 6 serves as a transition structure between transmission component 2 and rotating shaft 7, enabling a transmission connection between them. Specifically, when transmission component 2 is in the first position, it is transmissionally connected to connector 6. In this position, when the drive shaft 11 of the first drive component 1 drives transmission component 2 to rotate, transmission component 2 can drive connector 6 to rotate, thereby driving rotating shaft 7. When transmission component 2 is in the second position, transmission component 2 and connector 6 are disengaged. In this position, after the drive shaft 11 of the first drive component 1 drives transmission component 2 to rotate, transmission component 2 cannot drive connector 6 to rotate, allowing drive shaft 11 and transmission component 2 to idle, while rotating shaft 7 and connector 6 can rotate under external force.

[0085] like Figure 4 As shown, in some embodiments, the first housing 5 has a second mounting hole 54 formed in its wall, and the connector 6 is rotatably mounted in the second mounting hole 54.

[0086] It is understood that the connector 6 is installed based on the second mounting hole 54 formed in the wall of the first housing 5, so that one end of the connector 6 is located inside the first housing 5 and connected to the transmission component 2, and the other end of the connector 6 is located outside the second housing 8 and connected to the rotating shaft 7. The connector 6, the transmission component 2, and the rotating shaft 7 can be coaxially arranged.

[0087] It should be noted that a bearing can be installed in the second mounting hole 54. The connector 6 is connected to the inner ring of the bearing. This achieves a rotatable connection between the connector 6 and the first housing 5. A retaining ring can be provided on the outer surface of the first housing 5 to seal the connection between the outer ring of the bearing and the first housing 5.

[0088] like Figure 5 As shown, in some embodiments, the connector 6 includes a first connecting portion 61 that penetrates into the first housing 5, and the end of the transmission member 2 away from the first driving member 1 is provided with a mounting groove 22. The first connecting portion 61 is engaged in the mounting groove 22, and an anti-rotation portion for circumferentially limiting the two is provided between the first connecting portion 61 and the mounting groove 22.

[0089] It is understood that the first connecting part 61 is the portion of the connector 6 located inside the first housing 5, connecting the first connecting part 61 to the mounting groove 22 of the transmission component 2, and circumferentially limiting it through the anti-rotation part, thereby realizing the transmission connection between the connector 6 and the transmission component 2. When the first driving component 1 drives the transmission component 2 to rotate, the transmission component 2 can drive the connector 6 to rotate.

[0090] In some embodiments, the anti-rotation portion includes a spline disposed on the outer surface of the first connecting portion 61 and a spline disposed on the wall surface of the mounting groove 22. The spline on the outer surface of the first connecting portion 61 and the spline on the wall surface of the mounting groove 22 cooperate to achieve circumferential anti-rotation. At the same time, it allows relative sliding between the connector 6 and the transmission member 2, thereby switching the transmission connection between the transmission member 2 and the connector 6.

[0091] It should be noted that the spline on the outer surface of the first connecting part 61 has several first teeth arranged circumferentially, and the spline on the wall of the mounting groove 22 also has several second teeth arranged circumferentially along its inner surface. Because of the large number of first and second teeth, misalignment of the splines usually does not cause jamming. Even if misalignment of the splines causes the first connecting part 61 to jam with the mounting groove 22, the splines can be aligned by gently pushing the roller shutter to rotate the shaft 7 slightly.

[0092] Please continue reading. Figure 5In some embodiments, the connector 6 further includes a second connecting portion 62. The second connecting portion 62 is connected to the end of the first connecting portion 61 near the transmission member 2. When the transmission member 2 is in the first position, the entire area of ​​the second connecting portion 62 is located within the mounting groove 22. When the transmission member 2 is in the second position, at least a portion of the second connecting portion 62 is located within the mounting groove 22.

[0093] It is understandable that when the transmission component 2 is in the second position, at least a portion of the second connecting part 62 is located in the mounting groove 22, so the connector 6 will not completely detach from the mounting groove 22, so that the second connecting part 62 and the first connecting part 61 can be directly engaged in the mounting groove 22 during the resetting process of the transmission component 2.

[0094] like Figure 1 and Figure 2 As shown, according to a second aspect of this disclosure, a roller blind device is provided, which includes the aforementioned clutch mechanism. This roller blind device possesses all the beneficial effects of the aforementioned clutch mechanism, which will not be elaborated further herein.

[0095] Specifically, the roller blind device also includes a rotating shaft 7 and a roller blind. The roller blind is wound around the rotating shaft 7. The rotating shaft 7 is connected to the transmission component 2.

[0096] Please continue reading. Figure 1 and Figure 2 In some embodiments, the roller blind device further includes a second housing 8. The clutch mechanism, the roller blind, and the pivot 7 are all located within the second housing 8.

[0097] Understandably, by housing the clutch mechanism, roller shutter, and pivot 7 within a second housing 8 instead of a conventional roller, the second housing 8 serves two purposes: firstly, it provides storage and protection for the clutch mechanism, roller shutter, and pivot 7; secondly, it facilitates maintenance. When the clutch mechanism requires maintenance, there is no need to remove the roller shutter; simply opening the cover of the second housing 8 allows for easy and quick maintenance of the roller shutter device.

[0098] It should be noted that the second housing 8 has an opening extending along its length, and the rotating shaft 7 also extends along the length of the second housing 8. The first housing 5 of the clutch mechanism can be fixed inside the second housing 8 by fasteners. A mounting base 81 can also be provided inside the second housing 8. One end of the rotating shaft 7 is rotatably connected to the mounting base 81, and the other end is connected to the transmission component 2 through a connector 6.

[0099] According to a third aspect of this disclosure, a vehicle is provided that includes the aforementioned roller shutter device, and the vehicle has all the beneficial effects of the aforementioned roller shutter device, which will not be repeated here. Alternatively, the vehicle includes the aforementioned clutch mechanism, and the vehicle has all the beneficial effects of the aforementioned clutch mechanism, which will not be repeated here.

[0100] The vehicle may be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this disclosure does not make any specific restrictions.
