Description

Technical Field

[0001] This application relates to the field of sliding door technology, and in particular to an electromagnetic clutch, a sliding door system and its control method, a storage medium and an electronic device. Background Technology

[0002] Currently, electric sliding doors on vehicles are driven by a drive unit via a clutch. A fully open holding lock and a fully locked lock are installed in the fully open and fully locked positions, respectively, to lock the sliding door in the fully open and fully locked states. When the electric sliding door stops at a parking position between the fully open and fully locked positions, the holding clutch is engaged to prevent the drive unit from outputting torque, thereby limiting the sliding door's movement.

[0003] The current sliding door locking method requires a fully open holding lock, which increases the number of parts. Furthermore, when locking in the parking position, the position is locked by engaging a holding clutch, which increases the power consumption of the sliding door when parking. Summary of the Invention

[0004] The purpose of this application is to overcome the shortcomings of existing technologies, such as the large number of locking components and high power consumption during parking, and to provide an electromagnetic clutch, a sliding door system and its control method, storage medium and electronic equipment that can reduce the number of locking components and reduce power consumption during parking.

[0005] The technical solution of this application provides an electromagnetic clutch, including an active friction plate for connecting to a driving device, a driven friction plate for connecting to a driven device, and a coil for controlling the engagement of the driven friction plate with the active friction plate. A positioning gear is fixedly installed on the driven friction plate, and the positioning gear has positioning teeth in the circumferential direction.

[0006] The electromagnetic clutch further includes a locking lever and a driving component. The locking lever is movably mounted on one side of the positioning gear plate. The locking lever has locking teeth protruding toward the positioning gear. The locking teeth are used to engage with at least one of the positioning teeth to restrict the rotation of the driven friction plate.

[0007] The driving component is connected to the locking rod and is used to drive the locking rod to move relative to the positioning gear.

[0008] Furthermore, the locking rod is provided with a rotating shaft, which is rotatably mounted on the clutch housing;

[0009] One end of the locking rod is provided with the locking tooth, and the other end is provided with a support block. The driving member drives the locking rod to rotate around the rotating shaft through the support block.

[0010] Furthermore, the driving component includes a guide cam and a drive motor. The guide cam is linked to the support block. The drive motor is connected to a worm gear, and the guide cam is connected to a worm wheel. The worm gear and the worm wheel cooperate with each other. The drive motor drives the guide cam to rotate after transmission through the worm gear and the worm wheel, so that the guide cam pushes the support block.

[0011] Furthermore, the support block is connected to a first elastic element and a second elastic element, and the first elastic element and the second elastic element are connected to opposite sides of the support block along the direction of movement of the support block;

[0012] One end of the first elastic element is connected to the support block, and the other end is connected to the clutch housing;

[0013] One end of the second elastic element is connected to the support block, and the other end is connected to a guide block, which is connected to the driving element.

[0014] The technical solution of this application also provides a sliding door system, including a sliding door assembly, a sliding door drive device, and an electromagnetic clutch as described above. The sliding door drive device is connected to the active friction plate, and the sliding door assembly is connected to the driven friction plate.

[0015] The technical solution of this application also provides a sliding door control method for the sliding door system as described above, including:

[0016] In response to the sliding door sliding signal, the drive unit is controlled to drive the locking rod to separate from the positioning gear, and the driven friction plate is controlled to engage with the active friction plate through the coil;

[0017] The sliding door drive device controls the sliding door assembly to drive via the electromagnetic clutch;

[0018] In response to a sliding door stop signal, the drive unit is controlled to drive the locking lever so that the locking tooth engages with at least one of the positioning teeth;

[0019] The driven friction plate is separated from the active friction plate by the coil.

[0020] Furthermore, the locking lever is rotatably mounted in the clutch housing, and the drive component includes a guide cam and a drive motor, the drive motor driving the guide cam to rotate to push the locking lever to rotate;

[0021] The control of the driving component to drive the locking lever to separate from the positioning gear specifically includes:

[0022] Control the drive motor to rotate a preset angle along the first direction;

[0023] The control of the driving component to drive the locking lever so that the locking tooth engages with at least one of the positioning teeth specifically includes:

[0024] The drive motor is controlled to rotate by the preset angle along a second direction opposite to the first direction.

[0025] The technical solution of this application also provides a storage medium that stores computer instructions, which, when executed by a computer, are used to perform the sliding door control method as described above.

[0026] The technical solution of this application also provides an electronic device, including at least one processor; and,

[0027] A memory communicatively connected to the at least one processor; wherein,

[0028] The memory stores instructions that can be executed by the at least one processor, which enables the at least one processor to perform the sliding door control method as described above.

[0029] The above technical solution has the following beneficial effects:

[0030] In this application, an electromagnetic clutch is used, with a positioning gear installed on the driven friction plate and a locking rod provided on one side of the positioning gear. The locking rod can cooperate with the positioning gear to limit the rotation of the driven friction plate when the driven friction plate is separated from the driving friction plate. When the electromagnetic clutch is used in a sliding door system, when the sliding door stops at any position, it is not necessary to keep the driving and driven friction plates engaged. The rotation of the driven friction plate can be limited by the locking rod, thereby eliminating the fully open holding lock and reducing the energy consumption of the sliding door's parking slope.

[0045] Electromagnetic clutch:

[0046] The electromagnetic clutch in the embodiments of this application, such as Figure 1As shown, it includes an active friction plate for connecting to a drive device, a driven friction plate 01 for connecting to a driven device, and a coil for controlling the engagement of the driven friction plate 01 with the active friction plate. A positioning gear 11 is fixedly mounted on the driven friction plate 01, and positioning teeth 111 are provided in the circumferential direction of the positioning gear 11.

[0047] The electromagnetic clutch also includes a locking lever 02 and a drive element 03. The locking lever 02 is movably mounted on one side of the positioning gear 11. The locking lever 02 is provided with locking teeth 21 protruding toward the positioning gear 11. The locking teeth 21 are used to engage with at least one positioning tooth 111 to limit the rotation of the driven friction plate 01.

[0048] The drive unit 03 is connected to the locking rod 02 and is used to drive the locking rod 02 to move relative to the positioning gear 11.

[0049] like Figure 1 , 2 As shown, the driving friction plate, driven friction plate, and coil are all installed in the clutch housing 05. The driving friction plate and coil are installed in the clutch upper cover 04 and are concealed by the clutch upper cover 04. The axes of the driven friction plate 01 and the driving friction plate are on the same straight line. The coil is installed on one side of the driving friction plate. When the coil is energized, the driven friction plate 01 is attracted to the driving friction plate by the electromagnetic force of the coil. At this time, the drive device drives the driving friction plate to rotate, which in turn drives the driven friction plate 01 to rotate synchronously. The torque of the drive device can be transmitted to the driven device through the electromagnetic clutch. When the coil is de-energized, the electromagnetic force acting on the driven friction plate 01 disappears, and the driven friction plate 01 separates from the driving friction plate. At this time, the driven friction plate 01 rotates independently.

[0050] The driven friction plate 01 has a disc-shaped structure. The positioning gear 11 is fixedly connected to the driven friction plate 01, and the axis of the positioning gear 11 coincides with the axis of the driven friction plate 01. The positioning gear 11 and the driven friction plate 01 rotate synchronously. The positioning teeth 111 are evenly arranged on the outer circumference of the positioning gear 11, and extend outward radially from the positioning gear 11. The locking rod 02 is installed on the outside of the positioning gear 11. The locking rod 02 is at least partially movable in the direction of approaching and moving away from the positioning gear 11, so that the locking tooth 21 engages and disengages from the positioning tooth 111.

[0051] When the driven friction plate 01 engages with the driving friction plate, the locking tooth 21 separates from the positioning tooth 111, allowing the driven friction plate 01 to rotate synchronously with the driving friction plate. When the driven friction plate 01 separates from the driving friction plate, the locking tooth 21 can engage with the positioning tooth 111 to restrict the rotation of the driven friction plate 01. Therefore, it is not necessary to use the method of keeping the driven friction plate 01 and the driving friction plate engaged to restrict the rotation of the driven friction plate 01, which can effectively reduce the energy consumption of the clutch.

[0052] It should be noted that there can be one or more locking teeth 21. When there are multiple locking teeth 21, one of the locking teeth 21 can engage with the positioning tooth 111, or multiple locking teeth 21 can engage with the positioning tooth 111 at the same time.

[0053] In one embodiment, the locking lever 02 is provided with a rotating shaft 22, which is rotatably mounted on the clutch housing 05;

[0054] One end of the locking rod 02 is provided with a locking tooth 21, and the other end is provided with a support block 23. The driving component 03 drives the locking rod 02 to rotate around the rotating shaft 22 through the support block 23.

[0055] In this embodiment, the locking lever 02 is rotatably mounted in the clutch housing 05 via a rotating shaft 22. The rotating shaft 22 is located at the middle position of the locking lever 02. The locking teeth 21 and the support block 23 are respectively located at both ends of the locking lever 02. The driving member 03 drives the locking lever 02 to rotate around the rotating shaft 22 by pushing the support block 23, thereby causing the locking teeth 21 to move relative to the locating gear 11.

[0056] In one embodiment, the driving component 03 includes a guide cam 31 and a drive motor 32. The guide cam 31 is linked to the support block 23. The drive motor 32 is connected to a worm gear 33, and the guide cam 31 is connected to a worm wheel 34. The worm gear 33 and the worm wheel 34 cooperate. After being driven by the worm gear 33 and the worm wheel 34, the drive motor 32 drives the guide cam 31 to rotate, so that the guide cam 31 pushes the support block 23.

[0057] Specifically, since the diameter of the guide cam 31 is gradually changing, when the guide cam 31 rotates, it can push the surrounding components to move closer to or away from the axis of the guide cam 31.

[0058] In this embodiment, the output shaft of the drive motor 32 is connected to a worm gear 33, and the guide cam 31 is connected to a coaxial worm wheel 34. The drive motor 32 drives the worm gear 33 to rotate, and the worm gear 33 drives the worm wheel 34 and drives the guide cam 31 to rotate synchronously, thereby pushing the support block 23 linked with the guide cam 31 to move.

[0059] It should be noted that, due to the small size of structures such as the locking lever 02 and the guide cam 31, the power of the drive motor 32 used is also relatively small. Furthermore, the drive motor 32 only needs to be activated during the unlocking and locking of the driven friction plate, and does not need to remain in a continuous working state, resulting in low energy consumption. Compared to the existing technology that uses the attraction of the driven friction plate, this method effectively saves energy.

[0060] In one embodiment, the support block 23 is connected to a first elastic element 24 and a second elastic element 25, and the first elastic element 24 and the second elastic element 25 are connected to opposite sides of the support block 23 along the movement direction of the support block 23.

[0061] One end of the first elastic element 24 is connected to the support block 23, and the other end is connected to the clutch housing 05;

[0062] One end of the second elastic element 25 is connected to the support block 23, and the other end is connected to the guide block 26, which is connected to the drive element 03.

[0063] Specifically, a first elastic element 24 and a second elastic element 25 are connected in the direction of movement of the support block 23. The first elastic element 24 is connected between the clutch housing 05 and the support block 23. When the support block 23 is pushed towards the clutch housing 05 by the drive member 03 to separate the locking tooth 21 from the positioning tooth 111, the support block 23 compresses the first elastic element 24. When the drive member 03 removes the force pushing the support block 23, the first elastic element 24 extends to push the support block 23 back to its original position, so that the locking tooth 21 engages with the positioning tooth 111.

[0064] The second elastic element 25 is connected between the guide block 26 and the support block 23. The guide block 26 abuts against the outer peripheral surface of the guide cam 31. As the guide cam 31 rotates, it can push the guide block 26 to compress the second elastic element 25 and push the support block 23 to separate the locking tooth 21 from the positioning tooth 111.

[0065] Preferably, when the locking tooth 21 engages with the positioning tooth 111, the second elastic element 25 is in a compressed and energy-storing state. Then, when the locking tooth 21 engages with the positioning tooth 111, if the driven device drives the driven friction plate 01 to rotate synchronously under the action of an external force, and if the external force is sufficiently large, it can push the locking tooth 21 away from the driven friction plate 01. At this time, the support block 23 compresses the first elastic element 24. During this process, the second elastic element 25 releases energy to assist in pushing the support block 23 towards the first elastic element 24.

[0066] The electromagnetic clutch in this embodiment not only has a locking rod 02 to restrict the rotation of the driven friction plate 01, but also has an elastic element in the direction of movement of the locking rod 02 to provide a buffer space, so that the driven friction plate 01 can be unlocked and locked under the action of external force to achieve rotation.

[0067] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0068] Sliding door system:

[0069] The sliding door system in this application includes a sliding door assembly, a sliding door drive device, and the electromagnetic clutch in the aforementioned embodiments. The sliding door drive device is connected to the active friction plate, and the sliding door assembly is connected to the driven friction plate.

[0070] This application embodiment uses the electromagnetic clutch from the aforementioned embodiments in a vehicle sliding door. When controlling the sliding door to slide, the driven friction plate is controlled to engage with the driving friction plate, and the sliding door drive device drives the sliding door assembly to slide through the electromagnetic clutch. When the sliding door stops sliding, the driven friction plate can be controlled to separate from the driving friction plate, and the driven friction plate can be locked by the locking rod, thereby restricting the sliding of the driven friction plate and locking the sliding door assembly connected to the driven friction plate. This achieves locking of the sliding door at any position and reduces the energy consumption of the electromagnetic clutch.

[0071] Furthermore, when the user applies a large force to manually push the sliding door, the locking tooth 21 can be moved away from the driven friction plate 01 by pushing the driven friction plate, thereby pushing the sliding door to slide without affecting the effect of manually pushing and pulling the sliding door.

[0072] Sliding door control method:

[0073] This application provides a sliding door control method for the sliding door system described in the foregoing embodiments, such as... Figure 3 As shown, including

[0074] Step S301: In response to the sliding door sliding signal, control the drive unit to drive the locking rod to separate from the positioning gear, and control the driven friction plate to engage with the active friction plate through the coil;

[0075] Step S302: Control the sliding door drive device to drive the sliding door assembly through the electromagnetic clutch;

[0076] Step S303: In response to the sliding door stop signal, control the drive member to drive the locking lever so that the locking tooth engages with at least one of the positioning teeth;

[0077] Step S304: The driven friction plate is separated from the active friction plate by controlling the coil.

[0078] Specifically, the sliding door movement signal can include a sliding door opening signal and a sliding door closing signal. When the sliding door electronic control unit receives the sliding door sliding signal, it executes step S301 to make the driven friction plate and the active friction plate attract and release the rotation restriction on the driven friction plate. The two operations of controlling the driving component to drive the locking rod to separate from the positioning gear and controlling the driven friction plate and the active friction plate to attract through the coil can be executed simultaneously or sequentially, and the order of execution is not limited.

[0079] Then, based on the sliding door sliding signal, step S302 is executed to drive the sliding door assembly to move, thereby opening and closing the sliding door.

[0080] The sliding door stop signal in step S303 can be issued after the sliding door has slid to the fully open or fully closed state, or it can be issued by the sliding door electronic control unit when the sliding door has slid to any position between the fully open and fully closed states. When the sliding door stop signal is received, the control drive unit drives the locking lever to make the locking teeth engage with at least one positioning tooth, restricting the rotation of the driven friction plate, and then step S304 is executed to control the driven friction plate to separate from the driving friction plate.

[0081] Locking the driven friction plate before separating it can prevent the sliding door from sliding because the driven friction plate is in a free state after separation.

[0082] Furthermore, the locking lever is rotatably mounted in the clutch housing, and the drive element includes a guide cam and a drive motor, the drive motor driving the guide cam to rotate to push the locking lever to rotate.

[0083] Specifically, referring to the structure of the electromagnetic clutch in the aforementioned embodiments, the locking lever rotates via a drive motor, such as... Figure 2 As shown, during the process of the guide cam 31 rotating 90° counterclockwise, it can drive the locking rod 02 to release the locking of the positioning gear 11; when the positioning gear 11 is unlocked, during the process of the guide cam 31 rotating 90° clockwise, it can reset the locking rod 02 and lock the positioning gear 11 again, thereby locking the driven friction piece 01.

[0084] Based on this, the control of the driving component to drive the locking lever to separate from the positioning gear specifically includes:

[0085] Control the drive motor to rotate a preset angle along the first direction;

[0086] The control of the driving component to drive the locking lever so that the locking tooth engages with at least one of the positioning teeth specifically includes:

[0087] The drive motor is controlled to rotate by the preset angle along a second direction opposite to the first direction.

[0088] The technical solution of this application also provides a storage medium that stores computer instructions, which, when executed by a computer, are used to execute the sliding door control method in any of the foregoing embodiments.

The processor 401 executes various functional applications and data processing by running non-volatile software programs, instructions, and modules stored in the memory 402, thereby realizing the sliding door control method in the above embodiments.

[0098] The memory 402 may include a program storage area and a data storage area. The program storage area may store the operating system and applications required for at least one function; the data storage area may store data created based on the use of the sliding door control method. Furthermore, the memory 402 may include high-speed random access memory and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other non-volatile solid-state storage device. In some embodiments, the memory 402 may optionally include memory remotely located relative to the processor 401, and these remote memories may be connected via a network to the apparatus performing the sliding door control method. Examples of such networks include, but are not limited to, the Internet, intranets, local area networks, mobile communication networks, and combinations thereof.

[0099] The input device 403 can receive user clicks and generate signal inputs related to user settings and function control of the sliding door control method. The output device 404 may include a display device such as a display screen.

[0100] When one or more modules are stored in the memory 402, and are run by one or more processors 401, the sliding door control method in any of the above method embodiments is executed.
