If the motor 321 is arranged along the axial direction of the main shaft 325, the length of the door opening and closing assembly 32 is long, that is, the volume of the automatic door opening and closing device 30 is large, so that, in the present embodiment, the motor 321 may be arranged on one side of the main shaft 325 along the direction perpendicular to the axial direction of the main shaft 325, and the power of the motor 321 is transmitted to the main shaft 325 by the mutual matching of the power gear 3281 and the driving gear 3282.

Specifically, in one embodiment, power gear 3281 can be coupled to a motor shaft of motor 321 for rotation driven by the motor shaft, driving gear 3282 can be sleeved on main shaft 325 and coupled to main shaft 325, and power gear 3281 and driving gear 3282 can be engaged with each other to drive driving gear 3282 and main shaft 325 to rotate via power gear 3281.

When the user opens or closes the door manually, the door 20 may be driven to rotate at a faster speed, and thus the roller 322 and the spindle 325 may be driven to rotate at a faster speed. Since the driving gear 3282 and the power gear 3281 are engaged, a motor shaft of the motor 321 is caused to rotate, and thus, the motor 321 may be damaged.

Therefore, in the present embodiment, as shown in fig. 6 and 7, fig. 7 is a schematic cross-sectional view of the main shaft 325 and the driving gear 3282 in an embodiment of the present application. Drive gear 3282 may be disposed on spindle 325 and rotatable with respect to spindle 325, and door opening and closing assembly 32 may include a drive clutch 3283, where drive clutch 3283 is disposed on spindle 325 and is configured to connect or disconnect spindle 325 and drive gear 3282.

Specifically, when power gear 3281 rotates drive gear 3282, drive clutch 3283 couples spindle 325 and drive gear 3282, and drive gear 3282 rotates spindle 325 at a predetermined speed. When the door body 20 is subjected to external acting force to enable the rotating speed of the main shaft 325 to be greater than or equal to the preset rotating speed, the driving clutch 3283 can disconnect the driving gear 3282 from the main shaft 325, and then the main shaft 325 cannot drive the driving gear 3282 to rotate, so that the power gear 3281 and the motor shaft cannot rotate under the driving of the main shaft 325, and the motor 321 is protected.

Further, as shown in fig. 7 and 8, fig. 8 is a schematic perspective view of a driving clutch 3283 in an embodiment of the present application. Drive clutch 3283 includes a drive sleeve 3284, a first torsion spring 3285, and a first centrifugal pawl 3286. The driving sleeve 3284 is sleeved on the driving gear 3282, connected with the spindle 325 and spaced from the driving gear 3282, one end of the first centrifugal claw 3286 is rotatably connected to an inner side wall of the driving sleeve 3284 through a first torsion spring 3285, when the rotation speed of the roller 322 is less than a preset rotation speed, the other end of the first centrifugal claw 3286 is inserted into a gear groove of the driving gear 3282 under the action of the first torsion spring 3285, so that the driving gear 3282 is connected with the driving sleeve 3284, and the driving sleeve 3284 and the spindle 325 connected with the driving sleeve 3284 can be driven to rotate by the driving gear 3282. When the rotation speed of the roller 322 is greater than or equal to the predetermined rotation speed, the other end of the first centrifugal claw 3286 moves out of the gear groove of the driving gear 3282 to disconnect the driving gear 3282 from the driving sleeve 3284 under the action of centrifugal force, so that the connection between the driving sleeve 3284 and the driving gear 3282 is disconnected, and the driving sleeve 3284 does not drive the driving gear 3282 to rotate.

In some embodiments, as shown in fig. 8, the driving sleeve 3284 includes an end plate 3287 and a first surrounding wall 3288 disposed on one side of the end plate 3287, a mounting hole 3289 is disposed on the end plate 3287, the spindle 325 is inserted into the mounting hole 3289 in an interference manner, the first surrounding wall 3288 is disposed around the mounting hole 3289, and an avoiding groove 3280 is disposed on the first surrounding wall 3288, one end of the first centrifugal claw 3286 is rotatably connected to one side of the first surrounding wall 3288 away from the mounting hole 3289, the other end of the first centrifugal claw 3286 is provided with a weight block 32811, and the weight block 32811 is movably disposed in the avoiding groove 3280 and is used for being matched with a gear groove of the driving gear 3282. By disposing the first centrifugal claw 3286 on a side of the first surrounding wall 3288 away from the mounting hole 3289, the first centrifugal claw 3286 can be prevented from contacting the driving gear 3282 too much, and only the weight block 32811 inserted into the avoiding groove 3280 contacts the driving gear 3282, so as to prevent the first centrifugal claw 3286 from being damaged.

Further, the driving sleeve 3284 further includes a second surrounding wall 32812, the second surrounding wall 32812 is disposed on the end plate 3287 and surrounds the first surrounding wall 3288 and the first centrifugal claw 3286, so as to protect the first centrifugal claw 3286 and limit the first centrifugal claw 3286, so as to prevent the first centrifugal claw 3286 from being turned over due to a large centrifugal force, and when the centrifugal force disappears, the weight 32811 on the first centrifugal claw 3286 can be inserted into the avoiding groove 3280 again.

If the generator 327 is disposed along the axial direction of the main shaft 325, the length of the door opening and closing assembly 32 is long, that is, the volume of the automatic door opening and closing device 30 is large, so in the present embodiment, the generator 327 may be disposed on one side of the main shaft 325 in a direction perpendicular to the axial direction of the main shaft 325, and the rotation of the main shaft 325 may be transmitted to the generator 327 by the mutual cooperation of the transmission gear 3271 and the power generation gear 3272.

In one embodiment, the transmission gear 3271 may be connected to a motor shaft of the generator 327 for driving the motor shaft of the generator 327 to rotate, the power generation gear 3272 is engaged with the transmission gear 3271, the power generation gear 3272 is sleeved on the main shaft 325 and connected to the main shaft 325, and the power generation gear 3272 and the transmission gear 3271 are engaged with each other, so that the motor shaft connected to the power generation gear 3272 and the power generation gear 3272 is driven to rotate by the main shaft 325.

When the rotation speed of the main shaft 325 is less than the preset rotation speed, the main shaft 325 drives the power generation gear 3272, the transmission gear 3271 engaged with the power generation gear 3272, and the motor shaft connected to the transmission gear 3271 to rotate, and thus the generator 327 may be damaged.

Therefore, in the present embodiment, as shown in fig. 9, fig. 9 is a schematic structural view of the main shaft 325 and the power generation gear 3272 in one embodiment of the present application. The power generation gear 3272 may be sleeved on the main shaft 325 and can rotate relative to the main shaft 325, and the door opening and closing assembly 32 may include a power generation clutch 329, and the power generation clutch 329 is disposed on the main shaft 325 and is used for connecting or disconnecting the main shaft 325 and the power generation gear 3272.

Specifically, when the main shaft 325 rotates at a preset rotation speed, the power generation clutch 329 can disconnect the connection between the main shaft 325 and the power generation gear 3272, so that the main shaft 325 cannot drive the power generation gear 3272 to rotate, and a motor shaft of the transmission gear 3271 and the generator 327 cannot be driven by the main shaft 325 to rotate, thereby protecting the generator 327. When the door body 20 is subjected to an external acting force, so that the rotating speed of the main shaft 325 is greater than or equal to a preset rotating speed, the driving clutch 3283 can connect the main shaft 325 with the power generation gear 3272, the main shaft 325 can drive the power generation gear 3272 to rotate, and then the power generation gear 3272 can drive the transmission gear 3271 and a motor shaft of the generator 327 connected with the transmission gear 3271 to rotate, so that the generator 327 can generate power, and further the battery 326 is charged.

Further, as shown in fig. 9 and 10, fig. 10 is a schematic perspective view of the electric power generating clutch 329 in fig. 9. The generating clutch 329 includes a generator housing 3291, a second torsion spring 3292, and a second centrifugal pawl 3293. The generator housing 3291 is sleeved on the main shaft 325 and connected with the main shaft 325, and the generating gear 3272 is sleeved on the periphery of the generator housing 3291 and spaced from the generator housing 3291. One end of the second centrifugal claw 3293 is rotatably connected to the outer sidewall of the generator housing 3291 through a second torsion spring 3292, and when the rotation speed of the roller 322 is greater than or equal to a preset rotation speed, the other end of the second centrifugal claw 3293 moves in a direction away from the main shaft 325 under the action of centrifugal force, and is further inserted into a gear groove of the generating gear 3272, so as to connect the generating gear 3272 with the generator housing 3291, and further, the generator housing 3291 can drive the generating gear 3272 and a motor shaft of the generator 327 connected to the generating gear 3272 to rotate. When the rotation speed of the roller 322 is less than the predetermined rotation speed, the other end of the second centrifugal claw 3293 moves out of the gear groove of the power generation gear 3272 to disconnect the power generation gear 3272 from the generator housing 3291 by the second torsion spring 3292, and the generator housing 3291 does not drive the power generation gear 3272 to rotate.

In some embodiments, as shown in fig. 10, the generator housing 3291 is in interference fit with the spindle 325, an accommodating groove 3294 is formed on an outer side wall of the generator housing 3291, the second centrifugal claw 3293 is disposed in the accommodating groove 3294, a rotating shaft 3295 is disposed in the accommodating groove 3294 along an axial direction of the spindle 325, one end of the second centrifugal claw 3293 is rotatably connected to the rotating shaft 3295 through a second torsion spring 3292, and the other end of the second centrifugal claw 3293 abuts against a side wall of the accommodating groove 3294, so that when a rotational speed of the spindle 325 is less than a predetermined rotational speed, the second centrifugal claw 3293 is stably accommodated in the accommodating groove 3294 and avoids contacting with the power generation gear 3272.

Alternatively, the generator 327 and the motor 321 may be disposed on the same side of the main shaft 325, so that the door opening and closing assembly 32 is more compact and smaller.
