As shown in fig. 2, the clutch mechanism includes a clutch gear 3, and the clutch gear 3 has two positional relationships of an engaged position and a disengaged position. The meshing position is a position where the gear of the clutch gear 3 meshes with the drive gear 7 and the driven gear 2, and the disengaging position is a position where the gear of the clutch gear 3 does not mesh with the drive gear 7 and the driven gear 2. When the clutch gear 3 is in the engaged position, the driving gear 7 is engaged with the driven gear 2, and the driving rod 12 can be driven by the motor 9 to operate. When the clutch gear 3 is in the disengaged position, the driving gear 7 is not meshed with the driven gear 2, and the driving rod 12 can be driven to work manually. The engagement position and the disengagement position of the clutch gear 3 can be switched.

Further, as shown in fig. 2, the clutch mechanism further includes an adjusting mechanism. The adjusting mechanism is connected with the clutch gear 3 and is used for adjusting the position of the clutch gear 3 so that the position of the clutch gear 3 can be switched between an engaging position and a disengaging position.

As described in the background of the invention, the conventional electric driving device in the market is driven by the motor to work, and once the motor or the driving device has a problem, the electric driving device stops working and causes a loss. For example, in the conventional power sunroof, the opening and closing of the sunroof is driven by a motor. However, it is difficult to control the skylight in time in the case of motor damage, controller problems, switch failure and power failure. Once a problem occurs in the power sunroof, the manual operation of the sunroof can be performed only by detaching the motor to separate the driving system from the transmission system, which still needs to be familiar with the sunroof structure, otherwise, the sunroof needs to be sold by a manufacturer, which causes problems of time and labor waste, high cost and the like.

To the above existing problem that the conventional electric driving device can only be manually operated by detaching the motor to separate the driving system from the transmission system, which results in the technical problems of time and labor waste, high cost, etc., the electric driving device provided in this embodiment is configured such that, in the clutch mechanism, the adjusting mechanism can engage or disengage the clutch gear 3 with the driving gear 7 and the driven gear 2 by adjusting the position of the clutch gear 3. Further, the operation can be selectively performed by driving the driving rod 12 by the motor or the driving rod 12 by the hand according to the position of the clutch gear 3. Thereby realizing the effect that the manual driving transmission rod 12 and the electric driving transmission rod 12 can be switched. When having solved traditional electric drive device and having a problem, only can come actuating system and transmission system separation to carry out manually operation through demolising the motor to cause technical problem such as waste time and energy and with high costs.

Alternatively, the clutch gear 3 is provided with a clutch shaft 5 connected to the clutch gear 3, and a side surface of the clutch shaft 5 is provided with a recess 13, and wherein the adjusting mechanism includes a wedge 6, the wedge 6 is configured to be movable in a direction perpendicular to the clutch shaft 5, and one end of the wedge 6 is provided with a slope contacting the recess 13.

Specifically, as shown in fig. 3, the clutch gear 3 is mounted with a clutch shaft 5. The side surface of the clutch shaft 5 is provided with a recess 13. And, the adjusting mechanism includes a wedge 6, the wedge 6 is movable in a direction perpendicular to the clutch shaft 5, and one end of the wedge 6 is provided with a slope surface contacting the recess 13. Wherein the inclined surface of wedge 6 contacts recess 13 to exert an axially outward force on clutch shaft 5 as wedge 6 moves vertically toward clutch shaft 5. Thereby causing the clutch gear 3 to be switched from the engaged position to the disengaged position.

In this way, the clutch gear 3 is brought into the disengaged position by the wedge 6 and the recess 13 of the clutch shaft 5, so that the effect of the manual driving work is achieved. Moreover, the device is simple to operate and cheap, so that the cost of the electric driving device is reduced and the technical requirements are lowered.

Optionally, the other end of the wedge 6 is provided with an adjusting screw 8, wherein the adjusting screw 8 is rotatably connected with the wedge 6.

Specifically, as shown in fig. 3, the other end of the wedge 6 is provided with a rotatable adjusting screw 8. For example, the adjusting screw 8 can be in the form of a threaded screw, and by rotating the adjusting screw 8 the wedge 6 can be pushed vertically towards the clutch shaft 5, so that the clutch gear 3 is in the disengaged position. By controlling the movement of the wedge 6 in this way, the operation is simple and the technical requirements are reduced.

Optionally, a return spring 10 is sleeved on the clutch shaft 5.

Specifically, as shown in fig. 3, the clutch shaft 5 is fitted with a return spring 10.

Alternatively, the motor 9 is a stepper motor.

Specifically, the motor 9 employs a stepping motor. Because the precision of each step of the stepping motor is three to five percent, and the error of one step is not accumulated to the next step, the stepping motor has better position precision and motion repeatability, and has excellent start-stop and reverse response. The electric driving device can run more stably in the working process.

Optionally, the base 1 is further included, and the base 1 includes a mounting plate 14 and protrusions 16 and 17 extending from a surface of the mounting plate 14, wherein the driving gear 7, the driven gear 2 and the bearing 11 are disposed on the protrusions 16 and 17.

In this way, the electric drive apparatus can be mounted on the target product via the mounting plate 14, thereby facilitating mounting and dismounting of the electric drive apparatus. In addition, the driving gear 7, the driven gear 2 and the bearing 11 are mounted on the protruding portions 16 and 17, so that the positions of the driving gear 7, the driven gear 2 and the bearing 11 can be fixed without causing too much wear due to position deviation during rotation, thereby prolonging the service life of the device.

Alternatively, the protrusions 16,17 are a first protrusion 16 and a second protrusion 17 arranged in parallel, wherein the driving gear 7, the driven gear 2 and the clutch gear 3 are arranged between the first protrusion 16 and the second protrusion 17, and the bearing 11 and the adjusting screw 8 are arranged on the second protrusion 17.

Specifically, as shown in fig. 4, the projection 16 and the projection 17 are a first projection 16 and a second projection 17 parallel to each other, wherein the drive gear 7, the driven gear 2, and the clutch gear 3 are mounted between the first projection 16 and the second projection 17, and the bearing 11 and the adjustment screw 8 are mounted on the second projection 17. In this way, the driving gear 7, the driven gear 2 and the clutch gear 3 run more smoothly when they are held in position by the parallel protrusions. And the position of the adjusting screw 8 is fixed without deviation due to rotation, so that the moving direction of the wedge 6 is more accurate.

Alternatively, the second projection 17 is provided with a third projection 18 arranged in parallel with the clutch shaft 5, the third projection 18 being provided with a through hole 15 for mounting the adjusting screw 8, the through hole 15 being provided with an internal thread cooperating with the external thread of the adjusting screw 8.

In particular, the second projection 17 is also provided with a third projection 18, the third projection 18 being parallel to the clutch shaft 5 and being provided with a through hole 15 for mounting the adjusting screw 8, the through hole 15 being provided with an internal thread cooperating with an external thread of the adjusting screw 8. The adjusting screw 8 can thus be turned by the internal thread of the through hole 15, thereby pushing the wedge 6 towards the recess 13 of the clutch shaft 5.

Further, although not shown in the drawings, another aspect of the present embodiment also discloses a power sunroof including a movable window frame adapted to the power driving device of any one of the above, and the movable window frame is driven by the power driving device.

Specifically, when the power drive device is applied to a power sunroof, if a problem occurs in a motor or a drive system of the power sunroof, the clutch gear 3 can be disengaged from the drive gear 7 and the driven gear 2 by the adjustment mechanism. The roof window is then opened or closed by manually driving the transmission rod 12. Therefore, the problem that the skylight cannot be opened or closed to cause serious loss due to the problem of the motor or the driving system is avoided.

In summary, according to the embodiments of the present disclosure, the technical problems of time and labor waste, high cost, and the like caused by the fact that the manual operation can be performed only by detaching the motor to separate the driving system from the transmission system when the conventional electric driving device has problems are solved.
